  1. RHIC pp Setup Status Haixin Huang RSC Meeting 01/14/2011

  2. Overview of the week Yellow injection setup started Blue polarimeter setup measurements done First circulating beam with snakes RF capture with 28MHz cavity First turn seen in blue First circulating yellow beam with snakes Instrumentation setup, feedback setup

  3. Status • Blue • Injection setup is almost done. Most of the instrumentations were timed in and operational. • CNI polarimeter in Blue setup is almost done. Experts are working on making the device operational • Blue Tune/decoupling feedback system was tested. • Yellow • Circulating beam with snake on this morning • Need to do RF capture and instrumentation setup in following two nights. Haixin Huang

  4. Plan • We will work in next two owl shifts on yellow injection setup (RF capture and instrumentation setup). • Finish all the P/S works. This will take two shifts tomorrow • Yellow instrumentation setup • Tune/decoupling feedback system • CNI polarimeter • Others… • RF group will finish the loop setup tonight. • Fine tune blue and yellow injection with STAR magnet on. This should be quick • The near term goal is to start ramp development on Sunday. • 9MHz setup at injection is scheduled for Tuesday. Haixin Huang

  5. Tune/Coupling Feedback Works The working point at injection was too close to 2/3. It has been changed. Haixin Huang

  6. Dispersion Function Measured Haixin Huang

  7. Injection Damper Done Haixin Huang

  8. Emittancefrom CNI: 16,13 (H,V) Haixin Huang
