Description
Future high duty cycle (HDC) operating modes are under development for the
European XFEL. A L-band superconducting RF (SRF) gun is foreseen as the
injector operating continuous wave (CW). To preserve the small beam
emittance distracting effects like RF kicks from the power coupler,
trapped higher order modes (HOMs) in the cavity end group and RF field
asymmetries need to be considered and countermeasures to be taken. Apart
from the beam dynamics, the feasibility and effort of the manufacturing
and surface treatment, the later assembly and operation needs likewise
consideration. In our contribution we present the outcome of our studies
and the cavity end group which will be realized at our next prototype
cavities.
