LCLS-II Energy Overhead. Tor Raubenheimer. Klystron Configuration. LCLS-II similar to LCLS-I except shorter (5 fewer 5 stations) Extraction from 20-5, missing 19-7 and missing accelerator structures in 15-2, 14-2, 14-4 and 11-3

LCLS-II Energy Overhead Tor Raubenheimer
Klystron Configuration • LCLS-II similar to LCLS-I except shorter (5 fewer 5 stations) • Extraction from 20-5, missing 19-7 and missing accelerator structures in 15-2, 14-2, 14-4 and 11-3 • Girder 11-3 will be challenging to restore fully – not in cost estimates Accelerator and Detector PI Meeting Aug 22-23, 2011
LCLS-II Design Energy • Assuming reasonable repair margin, design energy less than 13.5 GeV including11-3 – costed design is down another 200 MeV
