Radiation Hardness of Subterahertz Radiation Source Based on Heterodyne on Gunn Diode Generator and Superlattice Multiplier
摘要
Abstract
The radiation resistance to gamma irradiation of various dose levels (0.5, 2, 10 kGy) of a subterahertz radiation source from a heterodyne on a Gunn diode and a GaAs/AlAs semiconductor superlattice multiplier was estimated. A measuring chamber for studying the radiation resistance of Gunn diodes has been developed and manufactured. The dependence of the output power on the frequency of a sub-terahertz radiation source before and after irradiation was evaluated analytically.
