TI - LCLS-II HE R&D Collaboration Overview J2 - Proc. of SRF2021, East Lansing, MI, USA, 28 June-02 July 2021 CY - East Lansing, MI, USA T2 - International Conference on RF Superconductivity T3 - 20 LA - english AB - This talk will present an overview of the LCLS-II HE R&D programs carried in collaboration between SLAC, Fermilab and Jlab in order to develop a new N-doping recipe and cavity processing protocol to meet the new challenging specifications and optimize flux expulsion management. Performance of the first set of cavities will be discussed comparing results from the vertical test to the cryomodule. Different aspects studied in detail during the verification cryomodule (vCM) test such as, multipacting processing optimization, Q-factor quench degradation and plasma processing will be discussed in this talk.
