  1. Sept. 2nd 2013: 1stH- beam in linac4 Linac4 H-source Matching the very tight of the 3MeV TS (mid. 2012) & L4-commissioning schedules (sept.2013) • Flexible front end suited for unprecedented IS-diversity : • Direct extraction of H- from the RF-H2 plasma volume (DesyVolume IS 20 mA) • Extraction of H-emitted form from a cesiated Mo-surface after impact of RF-H2 plasma produced H0 or p (SNS Surface IS 50 mA) • Extraction from an arc discharge induced Cs-H plasma (BNL’s Magnetron 100 mA) • Proton source (p, H2+, H3+) Dec. 13th 2013: First 50 mA pulse of the cesiatedsurface prototype Oct. 9th 2013: Nominal Linac4 beam tested @ BNL, 2 & 6.6 Hz Cs: 5 g/y Sept-2013
