AGS/Booster PP Setup Status

Haixin Huang. Feb. 19, 2013 Time Meeting. AGS/Booster PP Setup Status. Status. Established beam with snake on in one hour after switching to Siemens on 2/8, before snow storm hit us. The polarization is about 67%(1.7*10 11 )-70% (1.3*10 11 ) with JQ on.

  1. HaixinHuang Feb. 19, 2013 Time Meeting AGS/Booster PP Setup Status

  2. Status • Established beam with snake on in one hour after switching to Siemens on 2/8, before snow storm hit us. • The polarization is about 67%(1.7*1011)-70% (1.3*1011) with JQ on. • The new jump quad control application works. We have changed horizontal tune several times. Every time the new timing function worked better. • Scanned sin3v and cos3v in Booster. Confirmed h=4 is spin flipped in the stable region. • Done horizontal and vertical polarization profile measurements at injection. • JQ timing scan shown visible polarization difference. This is different from last year. • Booster input is about 4*1011. Haixin Huang

  3. AGS Operation not Affected by Snow Except waiting for plowing snow to access Bldg. 914. Special thanks to operation group who stayed onsite during the snow storm: Chris Naylor, Catlin Harper, Jordan Ziegler, Brian van Kuik, Reid Smith and many more. Haixin Huang

  4. First Polarization Intensity Scan The slope and interception are similar to last year. Haixin Huang

  5. Job List • AGS ring access to fix a dead Si detector tomorrow (open vacuum). • Continue to tune AGS for smaller emittance and higher polarization. • Will monitor the polarization throughout the RHIC setup period. • Prepare for radial jump test. • Reduce the AGS cycle time to 3.3 sec after we get jump quads operation stabilized with 4 sec. • Wait for chance to test two bunch mode in the AGS. • Ramp measurement to higher energy while waiting for extraction-on-the-fly test. Haixin Huang
