RHIC Run 11 Status Update Meeting: Critical Systems Review & Beam Development Schedule

This update covers the progress with RHIC critical systems, including AGS robustness, successful beam tests, polarimeters dry run, and feedback system readiness for ramp. The schedule outlines cryo cool-down, beam setup, and power supply work. Meetings planned for Jan. 3-9.

  1. RHIC Status of pp Run11 Haixin Huang Time Meeting 01/04/2011

  2. Critical Systems • AGS is robust to deliver 60-65% polarization with 1.5*1011 • AtR: beam has been dumped into W dump. • Ramp System • Tested successfully. • Two ramps in hands: one regular one and one with D’ shifted down • RHIC Injection • Switching between 9/28MHz cavities is expected to be smooth • RHIC CNI polarimeters • Dry run for down stream polarimeter has finished. Test run for upstream polarimeter will happen tomorrow. • Tune/orbit feedback on the ramp • Tune feedback is successful, orbit feedback will require beam for further test. The feedback system is expected to be ready for the first ramp.

  3. Schedule • Jan. 3-9 Cryo cool down, not much beam activity is expected, just a few owl shifts over the weekend. • The most optimistic estimate is to start beam setup in blue Friday night. Power supply work will take two shifts per day for the weekend, probably also first a few days next week. • The 9AM meeting will start on Friday. • The 3:30PM meeting for beam development will start when we have beam time during day time.
