FIELD: information technology.

SUBSTANCE: invention relates to methods of recording information on a material object, intended for providing long-term storage on the surface of objects – from among objects (articles) obtained as a result of economic activities, as well as specially made for long-term storage of information, with the possibility of fast information acquisition during reading. For the first time, a method and a multi-beam system are proposed, which generates streams of parallel beams of low energy ions with their immediate delivery to the region of action for input of information organized bitwise in form of optimal size, number, direction of movement, average kinetic energy of clots (bunches) ions of contrast agent, implanted in near-surface layer of object, made in a single body (a multi-beam data insertion tool).

Description

Technical field

The invention relates to methods for recording information on a material object, designed to provide long-term storage on the surface of objects - from among objects (products) obtained as a result of economic activity, as well as specially made for long-term storage of information, with the ability to quickly obtain information in the process of reading.

The claimed method can find application in the creation and filling of information carriers of long-term and reliable storage of information for current and future applications in mechanical engineering, aircraft manufacturing, art, as well as in other industries and human activities.

State of the art

Patented [1] methods for controlling low-energy beams of charged particles, including ions and the Markirator device that implements the described methods, allows one to obtain a focus spot, the size of steps along the surface and depth with values of the order of 1 μm, the number of particles (ions) in a bunch (bunche, cluster, fragment) 10 ³ -10 ⁸ and ion energy ≤1000 keV. The smallest possible cluster in terms of size and number of particles, entered into the surface layer of the object by the Markirator device, is recognized by the multi-range scanning speckle interferometric device Reader, which was also proposed in [1] and implements the methods described in the same patent as 1 bit of information. The specific information capacity estimated there, achieved by recording data identifiable with high reliability by applying minimally invasive identification marks on products, is estimated to be up to 1 Mbit / sq. mm in the case of using 2-dimensional (planar) marks and a level of up to 10 Mbps. mm in the case of 3-dimensional (volumetric) marks.

The use of modern advances in laser methods for producing accelerated charged particles provides an immediate opportunity to extend the method of applying and reading minimally invasive near-surface labels to the field of methods, devices, and media for long-term (archival, “eternal”) storage of information.

Description of the invention

For the first time, a method and a multi-beam system are created that creates flows of parallel beams of low-energy ions (PINES) with their direct delivery to the impact area for entering information organized bit by bit in the form of optimal in size, number, direction of motion, average kinetic energy of clumps (bunches) of contrast medium ions, implanted in the surface layer of the object, made in a single building (multi-beam data entry tool - mPIVD). The PINE multi-beam generator is based on laser methods for producing and accelerating particles using short-pulse (femto-attosecond) lasers with a high concentration of energy in a pulse interacting with special laser emitter targets (MIs). As a result of the interaction, clumps (bunches) of charged particles are born. The collimation and focusing of the bunches of the formed particles allows the creation of compact ion generators (ions, electrons and gamma quanta) of bunches with average ion energies of up to hundreds of MeV / nucleon and relativistic electrons accompanied by positrons and gamma quanta. The delivery of laser pulses to the target-focusing head (MFG), which is an output element for implanting bunches and reading recorded information, is provided by flexible optical fibers, which allows the creation of compact data recording devices.

Laser acceleration

Laser acceleration is provided by ion acceleration by the Coulomb explosion of cluster and solid-state emitter targets (MIs). The following laser acceleration options are also possible:

- acceleration of ions in the surface layer of MI;

- acceleration of ions by radiation pressure of light;

- acceleration of ions in a magnetic vortex;

- acceleration of ions at the front of a collisionless shock wave [2].

The process of obtaining accelerated ions by any (any) method is accompanied by the generation of fast electrons, the further propagation of which in a substance also gives rise to positrons and gamma rays.

Currently, the maximum energy of ions accelerated using thin solid-state emitter targets and femtosecond lasers is 40 MeV [3], 45 MeV [4], 160 MeV [5] for protons; 1 GeV (ie, 83 MeV / nucleon) for carbon [6].

Using the method of ion acceleration by the Coulomb explosion of cluster and solid-state target emitters (MI) allows you to create a compact installation with a gigawatt power in a pulse to generate ion (accompanied by electrons, positrons and gamma-quanta) bunches with a total intensity of 10 ¹⁰ -10 ¹² ions / sec and average energy up to 50 MeV / nucleon.

Using the above laser acceleration methods, bunches with complex ionic composition are generated, accompanied by electrons, positrons and gamma-quanta, which allows efficient recording of information (marking, as a method of creating memory) in the irradiated part of the object, as well as diagnostics (control the correctness of the process and the final result of entering information) of the irradiated and adjacent areas of the object [7, 8]. In addition, for example, if a proton beam is formed with a small addition of carbon and / or oxygen ions, then the formation of oxides / carbides will be stimulated in the substance of the object, which will additionally chemically affect the substance of the object, increasing the contrast of information clots.

The pulses of the forming laser are delivered via flexible optical fibers mounted in the used devices to the MFG. The target portion of the IFG is fragmented and sectoral in nature, i.e. fragments of different substances are included in it, which makes it possible to dynamically select a specific type of bunch ions during operation (different ion composition of the output beam) and the possibility of a multi-beam (multi-channel) read recording.

Several dozen identical individually controlled channels form the basis of a complete multi-channel (multi-beam) device for recording information, consisting of multi-channel SPINE (MKPINE), flexible optical fibers assembled in a bundle, multi-channel controlled optics (MKUO) as part of multi-channel MFG (MKMFG). The MKMFG design, as in the single-channel version, provides the ability to scan the head as a whole in a solid angle of 2π (4π if necessary) and, in addition, in the final section, the device of each channel allows you to have some additional range in the polar angle (relative to the axis of the initial beam) for individual synchronous asynchronous scanning.

The computing and control unit (BVI) controls the parameters of a multi-beam device for beam input of information (MPULVM), which is an element of the PIVD. The BVU manages the following characteristics of the ionic (ion-electron-positron-gamma-quantum) bunch by manipulating the parameters of the laser pulses and the target part of the head:

- the average energy of the bunch;

- the initial angular divergence of the bunch;

- the intensity of the bunch;

- the duration of the bunch;

- type of ion (ion-electron-positron-gamma-quantum) bunch.

Nature of the substrate

In the case of the option for long-term archival storage of information, specially made plates are used that meet the requirements depending on the purpose.

Bilateral (through) reading from relatively large depths of the entered information requires transparency in the ranges of the electromagnetic spectrum used for reading, the minimum number of chemical elements (isotopes) included in the basic structure of the base (substrate, information carrier), as well as the minimum amount of impurities. Thus, the recommendations for choosing a substrate for two-sided reading are transparency, purity (basic composition).

The minimum thickness for the information-significant layer of the substrate substance is at least 10 μm for two-sided reading and at least 30-50 μm for the layer providing rigidity and durability of the carrier.

Two-way reading materials are selected from the class of dielectrics or semiconductors; in particular, crystalline and amorphous — quartz, silicon, germanium, and others — will be suitable materials.

With one-sided reading (and, of course, a limited depth of entering information), it is possible to use a much wider range of materials, including metals.

Recording density

For the minimum sensitivity of the reader when reading 10 ³ atoms of any element of the periodic system selected for the introduction of 1 cc. μm, the number of particles introduced into the cell with a volume of 1 cubic meter microns can be varied over a wide range - 10 ³ -10 ⁵ ions (exceeding the level of 10 ⁵ ions for one cell is technically possible, but it will require a rather large energy cost and, therefore, is not always advisable).

To date, 115 chemical elements are known [9], of which 82 are in sufficient quantity in the earth's crust and are used in industrial activities, in addition, the number of different discovered isotopes of elements is ~ 3500, so an estimate of ~ 100 isotopes that can be used to provide a variety of types of information labels that are carriers of bits of information, is a lower bound.

Achievable in this case, the amount of information recorded on a quartz plate with dimensions of 10 × 10 × 0.01 cm ³ (the thickness of the working layer of the plate is ~ 10 μm, the remaining thickness to maintain the stiffness of the plate during long-term storage) will be about 1 Petabits (Pbit), or about 10 Terabit (Tbit) / cm ² .

The proposed method of using a minimally invasive multi-beam radiation low-energy information recording (the method of minimally invasive multi-beam radiation low-energy information recording - mIMPLNeZI), a reliable method for reproducing (reading) recorded information and a system that implements this method for the first time allows a new method and device for precise recording of information to be introduced for long-term storage by introducing information for long-term storage ultra-small doses (atto - clots, clusters, fragments) of contrast agents in a pointwise obnuyu spatial region irradiated target area.

The calculation of control parameters for the MIMPLNEZI beam device and the identity of the input information given are initially controlled in the computation and control unit due to the information received from the monitoring system integrated coaxially with the MKMFG.
