NEUTRON-PRODUCING TARGET ASSEMBLY Russian patent published in 2006 - IPC G21G4/02 H05H6/00 

FIELD: neutron-entrapping therapy.

SUBSTANCE: proposed neutron-producing target assembly has target with active material which is essentially thin-walled shell of revolution made in the form of sphere or cylinder and disposed within casing filled with circulating cooling medium. Charged particles arrive at target from accelerator outlet through inlet window whose dimensions are much lower than diameter of thin-walled shell. Neutrons being produced escape cavity filled with cooling medium through collimating outlet window. Assembly is provided with means for setting target in rotary motion and means preventing cooling medium ingress in inlet window space. Target in one of assembly alternatives is set in motion by means of drive. In other alternative target made in the form of sphere resides in cooling liquid within casing in suspended condition and is set in rotary motion by means of cooling medium flow.

EFFECT: simplified design and reduced size of apparatuses for conducting neutron therapy directly in cancer clinics and centers.
