Abstract
Superconducting radio frequency photoinjectors (SRF gun) seems to be a promising candidate to achieve the required brightness and the high average current for future light sources. In contrast to normal conducting DC and RF guns, higher order modes (HOM) and their influence on beam quality are of particular interest. For this reason, a method is presented that considers the accelerated motion of nonrelativistic electrons to calculate the longitudinal coupling impedances. The results are compared with first beam-based measurements and used to determine the required HOM damping. Additionally, a selective detuning of the eigenmode spectra is discussed.
Keywords: higher order mode; HOM; SRF gun
