  1. An ASSRC (Acc. Sys. Safety Review Com.) meeting was held on Sept. 24, 2013 •  I have gone around and talked … everybody (with due date  Dec. 15) has made or can make a statement now except the window calculation : • Perform beam particle analysis for full beam intensity, and luminosity. (Kin Yip, Due 12/15/13) • Calculate stress yield due to temperature rise on window at full beam intensity and beam spot size. (J. Tuozzolo, actually C. Pai, Due 1/30/14  12/15/13) • Estimate the time to remove beam from the machine when a NMC trips to determine if the time delay is adequate for machine protection. (A. Drees, Due 12/15/13)  we’ve been using it … • Estimate operational down time and effect to RHIC vacuum, if a vacuum loss occurs in the Roman Pot.(M. Mapes, Due 12/15/13)  a week • Determine effect upon Be beam pipe in STAR with a catastrophic vacuum loss in the Roman Pot. (W. Meng, Due 12/15/13)  no impact • Review NMC vs BLM operation or the use of both. Investigate electronic noise issues with NMCs to prevent inadvertent beam aborts. (D. Gassner, Due prior to Run 15). • Review/ update Operation Procedure OPM (TPL 09-09) for PP2PP operations. (P. Ingrassia, due prior to Run 15).
