ON THE POSSIBILITY OF OBTAINING A BEAM OF HEAVY IONS IN THE FORM OF AN “OPEN UMBRELLA” WITH SUBSEQUENT DEPOSITION IN THE SEPARATOR MANIFOLD

Abstract

The study of SNF reprocessing is impossible without obtaining and studying a multicomponent, low-energy and complex ion beam of an “umbrella” shape. The beam is obtained from a plasma flow created in a plasma source (PS) with a magnetic field of about 3 T, flowing along the axis into a weak magnetic field, at a level of 0.1…0.5 T. At the same time, its density decreases, and the entire energy of the plasma is converted into a jet directed along the axis. To randomize the particles of the jet plasma, a reflecting magnetic field is further placed on the axis. Without changing direction, the plasma flows in a hollow magnetic force tube around a solenoid with a reverse magnetic field. In this region, ions are drawn out in the radial direction towards the annular hole of the “pocket”. The target ions, M (230-277) follow umbrella trajectories and, being neutralized, are deposited in the “pocket” on the inner walls, the remaining ~ 3% are scattered and remain on the walls of the separator.
