Single cell standing wave tests data analysis Jiaru Shi Sep 27, 2011 LCWS11, Granada, Spain
Introduction Many single cell structures were tested at SLAC – Valery Dolgashev – To study RF breakdown with different geometries and different materials Many thanks to Valery Dolgashev, Yasuo Higashi Analysis data of single cell SW LCWS11, Granada, Spain
Note: To calculate field from recorded input power LCWS11, Granada, Spain
Summary BDR.v.s. (W --- stored energy) Best alpha between 0.5 ~ 0.7 for this four structure. (0.5 for pulsed surface heating) Equivalent pulse width calculated for standing wave structure with relatively long rising time More structures. New function? LCWS11, Granada, Spain
