Cathodes and Shape Modification of Cavity for DESY Superconducting Photoinjector
J. Sekutowicz, D. Bazyl, E. Vogel +8
Four DESY prototypes of the L-band superconducting RF photoinjector cavity demonstrated on-axis peak gradients above 55MV/m during multiple vertical cryogenic tests. Two of these p…

High gradients at SRF photoinjector cavities with low RRR copper cathode plug screwed to the cavity back wall
E. Vogel, J. Sekutowicz, D. Bazyl +13
In recent years we increased the typical maximum peak field on axis gradients obtained in L-band superconducting RF (SRF) photoinjector cavities at vertical tests to around 55 MV/m…
