Progress Update on Beam Work and Power Supply Developments - January 24, 2012

This status update outlines the progress of beam work across four scheduled shifts, including successful capture with good lifetime. Unfortunately, the last shift was lost to a 9 MHz failure. Significant advancements were made in the power supply setup, with the Blue beam delivered for injection a day early and the Yellow beam ready for tonight. Following the successful 100 GeV hysteresis test with Blue, preparations are underway for ramping and finalizing instrumentation. Ongoing work includes RF tests, BPM adjustments, and commissioning of new LLRF loops.

Presentation Transcript

  1. Progress of beam work • Four scheduled shifts with beam so far • Established captured beam with good lifetime (snakes on) and the bulk of instrumentation setup in the first three • Lost the last of the four to 9 MHz failure • Power supply progress • Blue delivered for injection 1 day early (Thanks, Don and co.!) • Yellow ready for injection tonight • Blue through 100 GeV hysteresis by tonight • Still planning on finishing p.s. work on 1/28. • RF work • Blue capture on new LLFR took 1 shift (as estimated, Thanks Alex and Kevin and co.!) RHIC Status Update Time Meeting, V. Schoefer 1/24/12

  2. RHIC Status Update Time Meeting, V. Schoefer 1/24/12 • To be done this week • At injection • Repeat the above with yellow • Finish instrumentation setup in blue • Orbit feedback tests • 10 Hz feedback tests • BPMs to fixed trigger • CNI setup in both rings • Prepare for ramping • Finish power supply work (inluding DX training) • Setup and commissioning of new LLRF loops • Begin 100 GeV ramp development
