More beam (muons) from the AGS AGS RHIC Users Group Meeting EDM Workshop Brookhaven National Laboratory 7 June 2006 Phil Pile Outline AGS Issues V1 Beam Line present limitations V1 Beam Line possible improvements To Do More beam from the AGS The experts BNL Hugh Brown V1 / Beam Line Design University of Illinois Peter Kammel Paul Debevec Sara Knaack They began studies over two years ago on how to improve Hugh Browns V1 beam line design. g-2 short history E821 (as run) Year Weeks HoursIntegrated Protons Remarks pulse-on-demand pulse-on-demand x st physics run pulse-on-demand x pulse-on-demand x x x TOTALS x E969 (my estimate) Commissioning x weeks with RHIC on AGS Total integrated protons (SEB+FEB), = 6.5 x 10 20 PROTON BEAMFY96 FY97 FY98/99FY2000 FY2001 FY2002 SEB SEBFEB (g-2)SEBFEB (g-2)FEB (g-2)FEB (g-2) SEB Beam Energy24 GeV24 GeV24 GeV24 GeV24 GeV24 GeV 24 GeV* 22 GeV* Peak Beam Intensity62 x ppp62 x ppp46 x ppp72 x ppp58 x ppp61 x ppp 63 x ppp 76 x ppp Total protons accelerated0.9 x x x x x x x x Spill Length/Cycle Time1.6 sec/3.6 sec1.6 sec/3.6 sec2.8 sec/5.1 sec2.4 sec/5.4 sec -> Duty Cycle44%44%55% 44% Spill Structure Modulation (peak-average) /average20%20%20%20% Average Availability /Best Week76% / 92%71% / 79%58 % / 67 %71% / 88%55 % / 83 %74 % / 87 %83 % / 88 %85 % / 97 % HEAVY ION BEAMAuAuFe (NASA)AuFe (NASA)Fe (NASA)Fe (NASA)Fe (NASA) Beam Energy /nucleon11 / 4 / 2 GeV11 / 8 / 6 GeV1.0 / 0.6 GeV11 GeV1.0 / 0.6 GeV1.0 GeV1.0 GeV1.0 GeV Peak Beam Intensity4 x 10 8 Au/p 17 x 10 8 Au/p 20 x 10 8 Fe/p 9 x 10 8 Au/bunch36 x 10 8 Fe/p17 x 10 8 Fe/p80 x 10 8 Fe/p49 x 10 8 Fe/p Spill Length/Cycle Time1.4 sec/3.6 sec1.5 sec/4.0 sec1.2 sec/3.0 sec0.9 sec/3.3 sec0.9 sec/3.3 sec0.9 sec/3.3 sec -> Duty Cycle39%38%40 %27%27%27% Spill Structure Modulation (peak-average) /average
