TIME Meeting, M. Minty, January 18, 2011
Instrumentation SystemsRHIC RUN-11 Startup
ramp development with simultaneous orbit, tune, and coupling feedback new timing setup procedure (defer)
new global orbit feedback (defer)
Ramp Development, RHIC RUN-11
leading cause of failure:poor orbit control
post-shutdown commissioning:
RUN-9 : 13 ramps until blue/yellow at 250 GeV RUN-11: 4 ramps until blue/yellow at 250 GeV
post mortem, RUN-9:
Ramp Development, RHIC RUN-11tune / coupling feedback - Y. Luo, A. Marusic, K. Mernick, M. Minty, M. Wilinski, + operations

history: proof-of-principle in RUN-6 (P. Cameron, Y. Luo, R. Jones et al) considerable modifications just before and during RUN-9 operational in RUN-10
