VACCUM-INSULATED TANDEM ACCELERATOR Russian patent published in 2017 - IPC H05H5/00 

FIELD: physics.

SUBSTANCE: invention relates to acceleration engineering and can be used to obtain charged particle beams for ion implantation, neutron capture cancer therapy or for detecting explosive and narcotic substances, as well as calibration of detectors of weakly interacting dark matter particles and other applications. In the disclosed tandem accelerator, between the low-energy negative hydrogen ion channel and the accelerator there is a metal ring, a cooled metal diaphragm, coated on the accelerator side by a mesh at negative potential, a vacuum pump, and at the output of the accelerator, the surface of the vacuum tank is covered by a mesh at negative potential.

EFFECT: reduced parasitic streams of charged particles in the acceleration channel, improved resistance of the accelerator to full voltage breakdown and high proton beam current.
