TY - CPAPER AU - Ross, M.C. TI - Technical Developments in Support of Accelerator-Based Science at SLAC J2 - Proc. of IBIC2014 AB - Recent recommendations from the Basic Energy Science Advisory Committee (BESAC) and the Particle Physics Project Prioritization Panel (P5) will have a significant long-term impact on accelerator development at SLAC. Most importantly, in summer 2013 BESAC recommended the number of FEL photon beam-lines in the 0.2 to 4 KeV range be increased substantially. This recommendation resulted in the proposal (LCLS-II), now accepted, to build a new 4 GeV CW superconducting linac in the same housing as the existing SLAC LCLS linac. The LCLS-II project involves contributions from several US partner-labs and is now in full-swing. BESAC also supported fully integrating the two FEL-linacs so that photon beam-line equipment could be used for either the high energy low-repetition rate beam or the moderate energy very high-repetition rate beam. The P5 report, on the other hand, strongly supported US involvement in the proposed International Linear Collider development, based in Japan. Both projects rely on the L-band superconducting RF technology under development for the last 25 years. The talk will report on recent technical developments and describe plans for future work.
