METHOD OF MAKING SHELL TARGET (VERSIONS) Russian patent published in 2016 - IPC H05H6/00 

FIELD: chemistry.

SUBSTANCE: invention relates to production of polymer shell targets for inertial thermonuclear synthesis. Method of making shell target at its first version involves formation of polymer shell, alloy additives, at first stage first, inner, and second outer film-blanks are made, then slice alloying are carried out separately first and second films-pieces of different types of additive particles respectively for first and second films billets so that alloying additive particles zone length corresponds to length of first and second films billets respectively, and preset width of zones of alloying is selected to that realise specified distribution of particles of additives along radius shell target; at second stage involves perforation of first film-blanks, then created projections of preset height and configuration at first film workpiece; at third stage involves cutting of first and second film piece so that their preset width and length so that they ensure preset number of layers of shell target; at fourth stage involves connection of first and second films of blanks over their length with preset adhesion; at fifth stage is connected to film-billets rolled so that forming roll is parallel to joint line films so that first film-blank forms working active layers, and second film-blank forms external ablator layers. First of ablation layers tightly adjoins outer turn of first film-blank, at such rolled preset number of layers of first film-blank determines size of active region of target, and number of layers of second film-blank determines target ablation layer thickness, then fixed outer edge of roll to produce enclosed target; at sixth stage is carried out simultaneously cutting resulting cylindrical roll to required length and end surfaces of workpieces of targets. Implementation of method of making shell target at its second version is similar to described above first version until performing of sixth stage. Difference consists in fact that after fifth stage, on which cylindrical billet shell target is formed, sixth stage is carried out. At this stage cylindrical billet shell target is compressed with two opposite sides. To ensure uniform distribution of force along area of billet shell target is placed between two flat plates, which strength is higher than strength of blank target.

EFFECT: technical result is possibility of commercial production of shell target at required repeatability of preset parameters of target with high strength characteristics.
