Resonant modes in A 1.6 cells RF gun

Massimo Ferrario, Concetta Ronsivalle

Research output: Contribution to journalArticle


The SPARC photoinjector RF gun consists in the BNL/SLAC/UCLA 1.6 cell structure designed to resonate at 2856 MHz in the % mode. It will be demonstrated by a numerical modelization based on SUPERFISH code combined with the LC-circuit analysis that the two oscillating modes of the system usually indicated as 0-mode and π-mode (the operating mode) are in reality a π/3-mode-like and a π-mode-like. The consequences on the definition of the coupling coefficient and on the use of mode-separation based RF measurements are described. © World Scientific Publishing Company.
