Definitions
- the invention relates to a monochromator device for selecting a wavelength band from incident radiation in a given wavelength range.
- X-rays or neutron beams it is known to use X-rays or neutron beams to perform various analyzes on materials. To do this, a source of X-rays or neutrons is necessary and, generally, a monochromator device is used, the purpose of which is to select a band of wavelengths (that is to say in energy) more or less narrow from the source spectrum whose wavelength range is too wide for the intended application. For X-ray radiation, the selection of a wavelength band is performed using the phenomenon of X-ray diffraction by a perfect crystal.
- an incident X-ray whose spectrum extends over a given wavelength range and which is received by a perfect crystal with a given angle of incidence gives rise to a diffraction of the radiation in a length band. narrower wave.
- the width of the wavelength band diffracted by the crystal depends on the nature of the crystal used (mesh parameter, crystal symmetry) and the selected crystallographic line. It is particularly known to use as a perfect crystal silicon, a material known for the quality and sufficient size of its crystals, for the ease with which it can be worked, as well as for its low cost.
- the bandwidth of silicon is too small compared to the spectral width of the sources used and it follows a considerable loss of flow.
- the bandwidth of silicon 111 is 1, 3 10 " 4 , which means that both third of the intensity of the incident radiation are lost. Silicon indeed has a resolution too high for applications using the X-ray diffraction technique.
- Germanium which is a material available in the form of perfect large crystals, which, because of a higher electron density than that of silicon, and therefore of line widths, is used as the perfect crystal. larger, transmits a flux three times higher than that transmitted by a silicon crystal.
- the cost of a material such as Germanium is higher than that of silicon and its mechanical characteristics (its elastic limit in particular) and thermal (thermal conductivity in particular) are less efficient than those of silicon. Therefore, it is difficult to envisage, with Germanium as crystal, applications where the curvature of the crystal must be variable and change depending on the application. Such applications are encountered when it is desired, for example, to focus X-rays at varying distances in order to adapt the optics to the apparatus or to focus different energies at a fixed distance.
- the objective of the focusing is to reduce the size of the beam produced at the level of the sample to be analyzed.
- the present invention aims to remedy at least one of the aforementioned drawbacks by proposing a monochromator device for selecting at least one wavelength band from incident radiation in a given wavelength range, characterized in that what it includes: at least one optical layer of a monocrystalline material whose crystallographic line is adapted to said at least one wavelength band to be selected,
- the monocrystalline nature of the material of the optical layer ensures, due to the arrangement of the crystal, the diffraction of the incident radiation.
- the invention thus makes it possible to obtain a monochromator device whose optical properties, with respect to X-rays or neutron beams, are decoupled from the mechanical and / or thermal properties of the substrate.
- the optical layer must be sufficiently thin. However, it must contain enough crystalline planes to diffract. For this reason, its thickness is, for example, greater than the extinction length of the material, which is a function of the crystallographic line of the chosen material.
- the monochromator device according to the invention is well adapted optically to the incident radiation thanks to the diffracting optical layer (s) of monocrystalline material (s). Thanks to the mechanical substrate, the device is easily handled and can be used in applications where it is deformed and, for example, curved, the mechanical substrate can be used to impose a flexion on the diffracting layer.
- the optical layer of the monochromator device which is made of a material that is generally more expensive than the material constituent of the mechanical substrate is only part of this device, which contributes to reducing the cost of the latter compared to a monochromator device which consists of a single monocrystalline material such as, for example, Germanium.
- the mechanical substrate is made of a material having mechanical characteristics greater than those of the constituent material of said at least one optical layer.
- said at least one constituent material of the mechanical substrate has a higher bending strength than the monocrystalline material constituting said at least one optical layer.
- said at least one optical layer has a thickness of between 0.2 and 100 ⁇ m.
- the monocrystalline material constituting said at least one optical layer is Germanium.
- the monocrystalline material constituting said at least one optical layer is chosen in particular from the following materials: AsGa, InSb, GaN, InP.
- the monocrystalline material constituting said at least one optical layer is chosen in particular from the following materials: silicon carbide, diamond, sapphire, lithium fluoride, quartz, BGO (Bismuth Germanate), YAG (Yttrium garnet) aluminum), GGG (Gallium Garnetium Gadolinium), GSGG (Scandium Garnet Gallium Gadolinium), Zirconium Oxide, Strontium Titanate.
- the device comprises at least two optical layers bonded one above the other and making it possible to select bands of different wavelengths, the monocrystalline material of one of the optical layers having a crystalline orientation different from the monocrystalline material of the other optical layer. These two layers may consist of the same crystalline material: in this case, these layers will have different crystallographic orientations which will be a function of the wavelength bands to be selected.
- the second optical layer may be the mechanical substrate which is, in this case, monocrystalline material.
- a complementary optical device may also be associated with the monochromator to enable one of the two selected wavelength bands to be selected.
- said at least one constituent material of the mechanical substrate is silicon.
- the mechanical substrate has a general shape of comb and has, on the rear face, a series of grooves which are substantially parallel to each other and perpendicular to said at least one optical layer bonded to the front face of said substrate.
- the radiation diffracted by the optical layer is reflected by this optical layer.
- the diffracted radiation can be transmitted by the monochromator: in this case, it is ensured that the mechanical substrate is capable of enabling this transmission, either by its transparency at the selected wavelength band, or by the performing opening (s) in said substrate.
- the invention also relates to a method for manufacturing a monochromator device for selecting at least one wavelength band from incident radiation in a given wavelength range, characterized in that it comprises a step of assembly by molecular bonding of a mechanical substrate with at least one optical layer of a monocrystalline material having a crystallographic line adapted to said at least one wavelength band to be selected.
- the mechanical substrate is made of at least one material having mechanical characteristics superior to those of the constituent material of said at least one optical layer.
- the method comprises a thermal treatment step in order to consolidate the molecular bonding forces between the two respective surfaces bonded to each other of the optical layer and the substrate.
- the temperature of this heat treatment must in particular be a function of the difference between the thermal expansion coefficients of the two materials (that of the optical layer and that of the mechanical substrate) in order to guarantee the integrity of the monochromator during this step.
- the method comprises a step of thinning said at least one optical layer.

- This source can also be a synchrotron source which emits X-rays in a continuous energy spectrum which is, for example, between 5 and 50 KeV .
- the system 10 also comprises a monochromator device 14 which is capable of selecting at least one wavelength band, as a function of the crystallographic line, of the material constituting the optical layer and of the angle of incidence of the incident radiation.

- the device 14 can transmit the diffracted beam.
- the selected band may be more or less narrow in the spectral width of the source.
- the curvature of the monochromator device 14 makes it possible to focus, according to the conventional laws of optics, incident X radiation 16 emitted by the source 12 on the sample 20.
- the angle of incidence is changed to select a different wavelength band, it may be useful to change the curvature of the monochromator to allow the radiation to be focused at the same distance as the wavelength band. previous.
- the monochromator device 14 is, for example, shown schematically in FIG. 2 in the non-curved position.
- This device comprises an optical layer 30 made of a monocrystalline material capable of diffracting X-radiation and this material is chosen such that its mesh parameter, its crystal symmetry and its crystallographic line are adapted to the wavelength band of the X radiation to select.
- This optical layer is, for example, made of monocrystalline Germanium and, more particularly, of Germanium 111.
- the constituent crystalline material of the optical layer can be replaced by one of the following materials: AsGa, InSb, InP, GaN to obtain specific wavelength bands.
- the monocrystalline material used as optical layer may be of lower electron density than that of Germanium and it is possible, for example, to use instead the carbide of Silicon, Diamond, Sapphire, Lithium Fluoride, Quartz, BGO, YAG, GGG, GSGG, Zirconium Oxide, Strontium Titanate.
- the optical layer has a thickness generally of between 0.2 and 100 ⁇ m and, for example, equal to 10 ⁇ m.
- the thickness of monocrystalline material that is necessary for X-ray diffraction is small (of the order of a few crystalline planes), which explains the small thickness of the optical layer which can thus be described as a thin layer. This is advantageous in that the The cost of the monocrystalline material used to constitute the optical layer is reduced.
- the monochromator device 14 of FIG. 2 also comprises a mechanical substrate 32 which is assembled to the optical layer 30 by molecular bonding at the interface 34 between the two components of the assembly.
- the mechanical substrate 32 is advantageously made of at least one material which has mechanical characteristics superior to those of the monocrystalline material constituting the optical layer 30 and which is directly compatible, or via an intermediate layer, with a molecular bonding.
- the material (s) constituting the mechanical substrate it is desirable for the material (s) constituting the mechanical substrate to exhibit (b) a higher bending strength than that of the material constituting the optical layer. 30, so that the resulting structure (Fig. 2) can be flexed repeatedly without damaging the monochromator device.
- Silicon the cost of which is much lower than that of the diffractive material used for the optical layer 30, will be used, for example, as a material for constituting the substrate 32.
- the greater part of the structure of the monochromator device 14 is made of an inexpensive material, if although the manufacture of the whole structure has a lower cost than that of a structure consisting solely of a material such as Germanium.
- the substrate 32 has, for example, a generally adapted form of comb.
- the substrate 32 in the rear face of the substrate 32 is a series of grooves which are substantially parallel to each other and perpendicular to the front face of the substrate bonded to the optical layer 30.
- Such a structure is therefore particularly adapted to adopt a variable curvature because of the great flexibility imparted by the grooves in a direction perpendicular to the latter.
- the structure has a high rigidity in a direction parallel to the grooves, which perfectly defines the angle of incidence of the incident beam and therefore the selected wavelength band.
- the mechanical substrate has a thickness, for example, of the order of a centimeter to allow easy manipulation of the optical layer and the monochromator in general.
- the thickness can however be close to several centimeters depending on the intended applications.
- the monochromator device according to the invention can also find interesting applications when it is necessary to obtain, with an optical system, several bands of wavelengths from the same incident beam of X-rays.
- an optical system when illuminated comprising a monochromator device comprising at least two adapted optical layers (one of the optical layers can be the substrate if it is suitable and, in particular, if it is made of monocrystalline material) using "white" synchrotron radiation (such radiation has, for example, all energies ranging from 5 to 50 KeV), the two optical layers each will reflect a different wavelength band.

- the structure with two superposed optical layers makes it possible to adapt the monochromator device to the desired resolution insofar as the lines of the monocrystalline material whose index is high give narrower reflections than those of the lines of the material whose index is higher. low. It should be noted that it is also possible to overlay more than two optical layers if necessary depending on the intended application.
- the manufacturing method provides for the use of a mechanical substrate, for example made of silicon, of shape, for example parallelepipedal, which has, for example, for example, a length of 120 mm, a height of 12 mm and a width of 80 mm (the width corresponds to the dimension perpendicular to the plane of Figure 2).
- the substrate has on the rear face a plurality of grooves, for example, spaced at a pitch of 1.5 mm, having a width of 1 mm and a depth of 11.3 mm.
- Such an arrangement gives the substrate particularly advantageous bending properties, in particular, sufficient rigidity in the direction of the grooves and great flexibility in the direction perpendicular to the latter. It should be noted that other substrates with different pitch, width and depth arrangements of the grooves can also provide satisfactory bending properties.
- the optical layer 30 of X-ray diffractive monocrystalline material can be made from a monocrystalline Germanium substrate.
- An oxide layer of a thickness of 500 ⁇ is for example deposited on the face of the Germanium substrate which is intended to be secured to the front face of the mechanical substrate 32, in order to facilitate the subsequent molecular bonding.
- This oxide layer is, for example, formed by a chemical deposit PECVD type ("Plasma Enhanced Chemical Vapor Deposition" in English terminology), that is to say a plasma-assisted vapor deposition.
- the front face of the mechanical substrate may also, if desired, coat an oxide layer.
- the faces of the silicon and germanium substrates intended to be secured to one another at the interface 34 of FIG. then prepared by known chemical treatments (wet or dry) in order to obtain a surface state compatible with a direct molecular adhesion between the faces of these two substrates, in particular in terms of surface roughness and hydrophilicity or hydrophobicity .
- the treatments applied to the substrates may be of the chemical-mechanical type.
- Substrates to be assembled are then contacted for molecular bonding.
- the manufacturing process comprises a heat treatment step that consolidates the bonding forces between the two faces in contact with the two respective substrates.
- This heat treatment consists, for example, in heating the two substrates at a temperature of between 150 and 250 ° C., which temperature is adapted to the difference between the coefficients of thermal expansion of silicon and germanium.
- the manufacturing method also provides for a subsequent step of thinning the substrate in Germanium to obtain a thin optical layer of a thickness for example equal to 10 microns.
- the thinning step can be performed mechanically, for example, by rectification, or chemically, using wet or dry etching techniques, or even mechanochemically.
- a chemical-mechanical polishing of the optical layer 30 can be carried out to obtain a layer of low hardening and low surface roughness shown in FIG. 2.
