Results of R&D Programmes and LP&CW EXFEL Cryomodule Tests in the Period from 2005 to 2023
J. Sekutowicz, D. Proch, J. Eschke +14
In 2005 and 2006, we began to consider the feasibility of long-pulse (LP) and continuous-wave (CW) operation for the E-XFEL. The operation modes considered were assumed to be compl…
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…
Prospects for CW and LP operation of the European XFEL in hard X-ray regime
R. Brinkmann, E. A. Schneidmiller, J. Sekutowicz +1
The European XFEL will operate nominally at 17.5 GeV in SP (short pulse) mode with 0.65 ms long bunch train and 10 Hz repetition rate. A possible upgrade of the linac to CW (contin…
Superconducting elliptical cavities
J. K. Sekutowicz
We give a brief overview of the history, state of the art, and future for elliptical superconducting cavities. Principles of the cell shape optimization, criteria for multi-cell st…
Superconducting Superstructure for the TESLA Collider: New Results
N. Baboi, M. Ferrario, M. Liepe +1
A new cavity-chain layout has been proposed for the main linac of the TESLA linear collider. This superstructure-layout is based upon four 7-cell superconducting standing-wave cavi…
