Description
In August 2014 the DoE Office of Science (Basic Energy Sciences) issued Critical Decision-1 for a Continuous Wave (CW) Free Electron Laser (FEL) to be built at SLAC, to be called LCLS-II. Designed to operate in tandem with the existing 14 GeV LCLS linac-based FEL, the new complex will produce a broad spectrum of X-ray photons for chemistry, molecular biology and materials studies. At the heart of the complex will be a new superconducting RF (SRF) linac based on 1.3 GHz cavity resonators originally designed for the TESLA linear collider proposal. Building on pioneering work done at Fermilab over the last few years, [1] these cavities are modified for CW operation and are designed to have a typical accelerating voltage of 16 MV/m. This talk will present development work in support of LCLS-II done by SLAC and its SRF partners: Fermilab, Jefferson Lab, Cornell University, and Argonne Lab.
