Abstract:
The Berlin Energy Recovery Linac Project (bERLinPro) is designed to develop and demonstrateCWLINAC technology for 100-mA-class ERLs. High-current operation requires an effective damping of higher-order modes (HOMs) of the 1.3 GHz main-linac cavities. We have studied elliptical 7-cell cavities based on a modified Cornell ERL design combined with JLab’s waveguide HOM damping approach. This paper will summarize the final optimization of the end-cell tuning for minimum external Q of the HOMs, coupler kick calculations of the single TTF fundamental power coupler (FPC) as well as multipole expansion analysis of the given modes and a discussion on operational aspects.
