Multipactor Discharge in Single-Gap Bunchers at 80 MHz

The results of calculating the threshold voltage levels causing multipactor discharge in single-gap buncher cavities at 80 MHz are presented in the article. Two types of gap geometry with an extension from 18 to 25 mm and with an extension from 18 to 80 mm are considered. The results of modeling a multipactor discharge using the MultP-M program are presented.
