Description

This invention relates to an accelerator technique and can be used to produce intense beams of ultrarelativistic polarized electrons and positrons for acting. protons accelerators with a projected and projected accelerator with an energy above several hundred gigaelectronvolt (GeV).

The aim of the invention is to increase the intensity of electrons (positrons), radiation polarized in a planar channeling mode in a bent single crystal, due to the fact that the volume formation of channeled electrons and positrons by an intense beam of hard y-quanta occurs directly in a bent single crystal.

Fig. 1 shows a diagram of the bulk formation of channeled electrons and positrons in a bent Mo; a crystal placed in a diverging beam of 1J quanta (the plane of single crystal bending is shown).

The possibility of implementing the proposed method under irradiation with accelerated protons of a beryllium target, behind which a cleaning magnet and a bent single crystal is installed, is illustrated in Fig. 2, where the calculated results are given: solid curves - the energy spectra of polarized electrons dNe / de, dotted curves - degree of polarization of electrons on the output of a curved single crystal. The length of the beryllium target is assumed to be 50 cm. Other data is given in the table, respectively, the numbering of the curves in FIG. 2.

The use of the proposed method for obtaining ultraretimulated polarized electrons and positrons provides:

obtaining intensities necessary for experiments; about 10 polarized particles per second with polarization of 30–60% using a relatively small fraction of the intensity of the proton accelerator (20%);

elimination of a complex energy-intensive magneto-optical system that forms an electron (positron) beam on a curved single crystal;

simplification of the procedure for tuning and maintaining the operating parameters of a beam of polarized electrons (positrons);

acceleration of the time spent on experimental studies in beams of polarized electrons (positrons), which also gives a real economic effect in the operation of experimental facilities;

the possibility of using both track and counter techniques with logical electronics with eco-experiments on beams of polarized electrons (positrons) due to the possibility of temporarily stretching the beam up to several seconds.
