Development of an irritation apparatus with catheter transmitting submillimeter wave for living bodies using a gyrotron

摘要

The development of a submillimeter wave catheter for irradiation on living bodies using a gyrotron as the radiation power source is described. The gyrotron FU-IV. optimized for such applications was used in the development. It we operated in CW regime at TE{sub}(03) mode with a frequency of 302 GHz setting the magnetic field of a superconducting magnet on ～11 mm. Irradiation tests using various antennas were performed on beef livers living rats and a cancer tumor implanted in living mice and are compared with the simulation results.
