ACCELERATOR SEMINAR 

"RF Operational Experience with High QL SRF Cavities" 

Tomasz Plawski 
Engineering Division, Jefferson Lab 

Jlab is currently commissioning ten new  C100 cryomodules, a major part of the 12 GeV  Energy Upgrade Project.  For each of  eighty cavities, a new LLRF system has been installed and now is undergoing  rigorous tests.  The CEBAF 12 GeV  energy upgrade cavities have a QL of 3 X 10^7 and  operate at gradients of 20 MV/m.   Operation of these cavities is challenging due to their microphonic sensitivity, cavity to cavity  mechanical coupling and Lorentz force detuning.   In this presentation we will discuss these issues.  Possible improvements and future design  concepts will be addressed in conclusion.
