Description
Technical Field
The invention belongs to the field of laser fusion, relates to a proton detection technology, and particularly relates to a compact proton energy spectrum measuring device applied to nuclear fusion research.
Background
Fusion energy is clean energy without pollution, and countries in the world compete for the research and development of relative technologies to invest a large amount of manpower and material resources. However, the conditions for realizing fusion are very harsh, and the fuel needs to reach extremely high temperature and high pressure, and laser inertial confinement fusion and magnetic confinement fusion are two most promising technical approaches for realizing the conditions at present.
In laser inertial confinement fusion, in order to achieve the "central hot spot" dh (dianhuo) condition of fuel, enormous-scale laser driving devices are built or planned in countries around the world, such as: the NIF device, which has been built in the United states, has 192 high-energy lasers with an output energy of 1.8 MJ; french under construction LMJ device with 240 high-energy lasers and 1.8MJ output energy; the Russian is in Ka-n-bMep construction, and 2.0MJ energy is output.
In recent years, in addition to continuously enlarging the scale of a laser driving device, a scheme for realizing fast DH (DH) based on a high-energy proton beam is also provided, namely when fusion fuel is compressed to the maximum density, a beam of ultrashort ultrastrong laser pulse is focused on the surface of a target pellet, extremely high ponderomotive force punches a hole on a plasma critical density surface on the surface of the target pellet, the critical density surface is pressed to a high-density nucleus of a target core, a large amount of Mev energy high-energy proton beams are generated in the process, and the proton beam penetrates through the critical density surface and is shot into the high-density nucleus, so that the temperature of ions is rapidly increased, and the fast DH is realized. The fast DH scheme has received much attention because it will greatly reduce the drive laser energy; the high-energy proton beam generated by the ultra-strong laser driven thin film target also becomes a hot point of research.
Currently, proton photographic image recording is typically performed using a stack detector consisting of a stack of radiochromic membranes (RCF) and filters. Proton beams are irradiated onto an RCF stack detector, high-energy protons have high movement speed and long range, and energy is mainly deposited on a rear RCF layer; the low-energy proton has low moving speed and short range, energy is mainly deposited on the RCF layer in front, and proton energy spectrum information is obtained by comparing images recorded by different layers of RC F. The method needs to analyze images of the membranes of different layers after experiments, has low efficiency, and is easy to pollute the personnel by radiation. Therefore, it is urgently needed to design a proton detection device to realize experimental measurement and research on the directivity, energy spectrum and other characteristics of a proton beam generated by the action of ultrashort ultrastrong laser pulses and the surface of a target pill.

Compared with the prior art, the invention has the advantages that:
1. the measuring device adopts the wedge-shaped filter disc to filter the proton beam energy spectrum, and the energy spectrum is incident to the scintillator to excite visible photons, then the imaging lens images the space distribution information of the visible photons onto the image enhancement target surface of the detector, and because the energy of the protons which penetrate through the wedge-shaped filter disc at different thickness positions is different, the continuous energy spectrum information of the protons can be obtained through the wedge-shaped filter disc, and the proton energy spectrum measurement is realized; the imaging lens adopts an object space telecentric system, and has high fidelity in the light intensity space distribution imaging process, so that the light receiving solid angles of each point of the scintillator are consistent, and the directions of the collected light beams are consistent.

Detailed Description
The invention is described in further detail below with reference to the figures and specific embodiments.
As shown in fig. 1, a compact proton energy spectrum measuring device based on a wedge-shaped filter and a scintillator comprises a wedge-shaped filter 1, a scintillator 2, an imaging lens and a detector which are coaxially arranged in sequence along the proton emergent direction; proton beams are incident into a large-area wedge-shaped filter disc 1, and are incident into a scintillator 2 after being filtered by an energy spectrum of the wedge-shaped filter disc 1 to excite visible photons, and then the excited visible photon spatial distribution information (images) is imaged on an image enhancement target surface 12 of a detector by an imaging lens.
The thickness of the thin edge of the wedge-shaped filter disc 1 is 0.2 mm-2 mm, the thickness of the thick edge is 1.0 mm-10 mm, and the thickness of the thin edge is smaller than that of the thick edge, in the embodiment, the thickness of the thin edge is 0.4mm, the thickness of the thick edge is 2.0mm, the surface shape of the wedge-shaped filter disc 1 is rectangular, and the size specification is 40mm multiplied by 40 mm; the proton energy penetrated by the positions of the filter discs with different thicknesses in the wedge-shaped filter disc 1 is different, so that the continuous energy spectrum information of the proton can be obtained through the wedge-shaped filter disc 1, and the proton energy spectrum measurement is realized.
The protons transmitted by different positions of the wedge-shaped filter 1 are incident to the scintillator 2, the energy is stored in the scintillator 2, and visible photons (thermoluminescence) are emitted, and the material of the scintillator 2 is BC 422.
The imaging lens collects the visible photons (thermoluminescence) emitted by the scintillator 2, images the photon space distribution image onto the image enhancement target surface 12 of the detector, and records the image by a subsequent CCD camera after the image is enhanced.
Since the light emitted from the scintillator 2 has a large solid angle, it is generally difficult for the imaging lens to collect all the light emitted from the scintillator 2. However, it should be ensured that the light receiving rate of the imaging lens for each point of the scintillator 2 is consistent, so that the light intensity distribution of the image plane can actually reflect the photon spatial distribution of the object plane of the scintillator 2. In order to ensure the consistency of the light receiving rate, the imaging lens of the embodiment adopts an object space telecentric optical path, so that the light receiving solid angles of each point of the scintillator 2 are consistent, the directions of the collected light beams are consistent, the numerical aperture NA of the object space of the imaging lens is 0.164 (the light receiving half angle is 9.5 degrees), and the inconsistency of the collection efficiency of each point of an object plane (40mm multiplied by 40mm) is 2%.
According to the characteristic of the light-emitting spectrum (350nm-450nm) of the scintillator 2, the imaging lens should be made of an ultraviolet high-transmittance optical glass material, and in order to improve the light transmission efficiency of the imaging lens, an ultraviolet antireflection film should be plated on the surface of an optical element of the imaging lens, but the ultraviolet high-transmittance optical glass material is relatively short, so that the cost is relatively high. Therefore, the imaging lens of the present embodiment adopts the structure shown in fig. 1, and includes a first lens 3, a second lens 4, a third lens 5, a fourth lens 6, a fifth lens 7, a sixth lens 8, a seventh lens 10, and an eighth lens 11, which are arranged in this order in the proton outgoing direction. When the measuring device is used, the measuring device is positioned in a vacuum environment, but a common detector cannot work in vacuum, so that the detector can adopt a vacuum sealing detector; the wedge-shaped filter 1, the scintillator 2 and the imaging lens can also be positioned in a vacuum environment, and the detector is positioned outside the vacuum environment, but because the distance between the detector and the imaging lens is small, if a sealing window is arranged between the detector and the imaging lens, the whole lens needs to be expanded in the same proportion, so that the volume of the measuring device is large. In practical applications, an atmospheric chamber/bag is often designed in vacuum, and the detector is placed in the atmospheric chamber/bag, the chamber/bag is communicated with the atmosphere through two sealed air pipes, one is used for air intake and one is used for air exhaust, and the detector in the atmospheric chamber/bag is cooled by gas (or liquid and cooled by heat transfer). Therefore, a vacuum sealing window is required to be arranged between the imaging lens and the detector, light can pass through the vacuum sealing window, and sealing is achieved at the same time.
In order to improve the spatial resolution of the imaging lens, the third lens 5 of the imaging lens adopts an aspheric surface, so that the chromatic aberration of the system is greatly reduced, and the spatial resolution of the imaging lens on the scintillator 2 is less than 30 microns.
The parameters of the optical elements in the compact proton energy spectrum measuring device of the embodiment are shown in the following table 1;
TABLE 1 parameters of optical elements in compact proton spectrometer
The coordinate data in the table is a right-hand coordinate system as shown in fig. 1, the horizontal right is the + Z axis, the vertical paper surface is the + X axis inwards, and the vertical paper surface is the + Y axis upwards. The spherical radius sign of the lens is defined as follows: if the center of the sphere is on the left side of the sphere, the radius is negative, and if the center of the sphere is on the right side of the sphere, the radius is positive. The third lens 5 is an even-order aspheric surface, and the surface type formula is shown as formula (1):
in the formula: z is the reflector rise; c is the reciprocal of the spherical radius; k is a coefficient of a quadratic curve; alpha is alpha1～α3: an even aspheric coefficient; r is the radial variable.
As can be seen from table 1, the imaging lens has a large object field (40mm × 40mm), and by using the aspheric lens, the structure of the lens is simple and compact (total length is 425mm), and meanwhile, the optical system can obtain a high object spatial resolution (less than 60 micrometers); the optical system adopts a separated structure without a gluing surface, and the light transmittance performance of the system is prevented from being influenced after the optical cement is subjected to radiation denaturation.
The above description is only for the purpose of describing the preferred embodiments of the present invention and does not limit the technical solutions of the present invention, and any known modifications made by those skilled in the art based on the main technical concepts of the present invention fall within the technical scope of the present invention.
