  1. Energy Deposition Group2008: N. Mokhov, A. Drozhdin, M. Kriss, I. Rakhno, S. Striganov Nikolai Mokhov APC General Meeting 11 March 2008 N. Mokhov: Energy Deposition Group

  2. Recent Accomplishments (1) • Main Injector:Collimation system design (AD, NM, IR) • Tevatron:Crystal collimation experiment: justification (AD, NM) • LARP & CMS:Feasibility of IR configurations at 1035: SC magnets and detector backgrounds (NM, IR) • ILC:Beam Delivery System (collimation and muons); 0.15 to 5 GeV transfer line collimation; dark current beam loss in Main Linac; ILCTA beam dumps and shielding (AD, NM, SS) • MTBF, MuCool, HINS, Booster, MERIT, kaon experiments, muon collider:Particle yields, energy deposition, beam loss, shielding (AD, NM, IR, SS) • MARS Code:Development of advanced physics models and extension of capabilities (NM, IR, SS) • Computer Servers:Relocated to XGC-108 & USPAS support (MK) APC General Meeting 11 March 2008 N. Mokhov: Energy Deposition Group

  3. Recent Accomplishments (2) Beam-loss muon backgrounds at CMS Main Injector collimators K+ yield at 8 GeV: MARS vs data vs old models Crystal collimation optimization LHC Phase-I JIRS: NbTi/Nb3Sn triplet w/absorbers APC General Meeting 11 March 2008 N. Mokhov: Energy Deposition Group

  4. Computing Support • Cartoon Cluster • 16 Sun Solaris servers • 6 Intel/AMD Linux servers • 300+ users • APC • 40+ users • USPAS • Relocated servers to XGC-108 • Room for growth • Better A/C • Power circuits • Heimdall Cluster • 64 slave nodes and growing! • 60+ users and growing! APC General Meeting 11 March 2008 N. Mokhov: Energy Deposition Group

  5. CY08 Plans • Tevatron/LARP:Crystal collimation experiment: replace crystal & goniometer, extend beam diagnostics, EOS beam studies, MOU and work towards full-scale studies in 2009-2010 • Project X:Design of MI primary and secondary collimators compatible with higher rate and able to withstand accidental intercept of the full beam; phase-space painting injection; collimation in 8-GeV Linac and transfer lines • LARP & CMS:Joint IR studies (JIRS) for LHC Phase-I upgrade (2.5e34) to optimize the triplet with a US Nb3Sn quadrupole; beam induced operational backgrounds and accidental rad. loads on CMS • Muon Collider:56-GeV MI beam (targetry etc.), backgrounds for new MC parameters and strawman detector, exotic beams • ILC (?), MARS Code (HI, DPA, EMS, GUI), etc. APC General Meeting 11 March 2008 N.
