Receiver protector protects the radar receiver while transmitting radar power. In recent years, the use of radioactive sources as an auxiliary electron source in the receiver protector has led to the generation of a regular breakdown voltage and is one way to prevent damage to the receiver. In this paper, a mixture of cobalt source (as a radioactive source) and helium gas are used to produce a radioactive ignitron. The MCNPX code is used to calculate the deposition energies in the receiver chamber. Then, the electrical potential energy caused by ionization of radioactive source in different activities is determined with CST software at a working frequency of 12 GHz.
