  1. Misalignments + Jitter with 1 corrector + 1 BPM per focusing period (45mA, pulsed linac front-end up to ~38 meters) Jean-Paul Carneiro FNAL Accelerator Physics Center April 16th , 2010 10 mA (Last week results @ 10 mA as well)

  2. Which lattice: 10 mA Nov 2006 lattice • Which TRACK: TRACKv36 • How many runs: statistics on 100 runs (FermiGrid) • How many particles per run : 1 Million (“real” distribution from RFQ) • Which errors: (Nov 2006 set) • Zero error exit RFQ “zero 0.01 0.07” (Xc, Yc, [cm], X’c, Y’c [mrad]) • Delta_xy cav (Buncher, + 16 RT) : 500 microns • Delta_xy cav (SC) : 1 mm • Phase + Fields: 0.5 deg RMS 0.5% RMS • Delta_xy Quads: 300 microns • Delta_xy Sol (Buncher+RT+SSR1) : 300 microns • Delta_xy Sol (SSR2) : 400 microns

  3. What about the correctors: MEBT : as in Nov 2006 (2 correctors + 1 monitor) RT section + SSR1 + SSR2 (1 CM): 1 corr + 1 mon / sol Monitor resolution : 30 microns Monitor alignment : 100 microns + 500 microns Monitor Max Strength unlimited : 5 mrad Some datas: (100 runs, 1M particles per run) • Errors + No corrections : 69229 lost particles (~7.1E-4 total beam losses) • Errors + “Nov 06 type corrections” : 2132 (~2.2E-5) 6 corr + 2 mon in RT section, 2 corr + 1 mon / cryomodule) • Errors + “April 2010 type corrections” : 431 (~4.4E-6) 30 μm Res. / 100 μm Alg. 1 corr + 1 mon / solenoid • Errors + “April 2010 type corrections” : 430 (~4.4E-6) 30 μm Res. / 100 μm Alg. 1 corr + 1 mon / solenoid (~1E-2 W/m)

  4. 1 corr + 1 BPM / sol (RT section, SSR1, SSR2 (1 CM) at 10 mA 30 μm Res. / 100 μm Alg. / 5 mrad 30 μm Res. / 500 μm Alg. / 5 mrad

  5. Which lattice: 10 mA Nov 2006 lattice Which TRACK: TRACKv36 How many runs: statistics on 100 runs (FermiGrid) How many particles per run : 1 Million (“real” distribution from RFQ) Which errors: Delta_xy Sol (Buncher to SSR2) : 1000 microns What about the correctors: MEBT : as in Nov 2006 (2 correctors + 1 monitor) RT section + SSR1 + SSR2 (1 CM): 1 corr + 1 mon / sol (Remark: sol. Misl. ONLY , no RF jitter) Monitor resolution : 10 microns Monitor alignment : 100 microns Monitor Max Strength unlimited Datas: 1 mm sol xy / 1C+1M/sol. / 10 microns Res. / 100 microns. Alg. No limit on max strength  77 lost particles (on 100*1M=100 M) Losses to negligible ~1E-4 / 1E-5 W/m

  6. 1 corr + 1 BPM / sol (RT section, SSR1, SSR2 (1 CM) at 10 mA 10 μm Res. / 100 μm Alg. / No limit on corr strength Losses > 100 W/m < 1E-4 W/m
