  1. HCALTestbeam plans HCAL Main meeting at DESY September 29, 2005 HCAL Main Meeting

  2. Brief update • DESY • CERN • FNAL HCAL Main Meeting

  3. DESY • Ongoing: HCAL module ONE • Data taking almost complete, see Erika’s talk • Next (Oct-Nov): Tail catcher (TCMT) integration • Start in HCAL test tent, then move into beam • Jan 06 and on: with precision tracking (Japanese DC) • ECAL full depth (laterally not yet complete) • ECAL + HCAL • HCAL uniformity HCAL Main Meeting

  4. T2 target from SPS T4 target CERN SPS North Area • H2, H4 and H8 beams • 10 - 400 GeV/c, up to 108 particles/spill (π+) • H4 can be set-up for very clean electron beam (up to ~300 GeV/c) • H2 and H8 also have low energy tertiary beams (2 – 10 GeV/c) • H6 beam • 5 – 205 GeV/c, up to 108 particles/spill (π+) (at 5 GeV ~1000 particles / spill) • Up to 3 experimental areas per beam line (parasitic muon runs possible) 50 m HCAL Main Meeting

  5. SPS and PS schedules • Almost final (to be approved Sep 1, changes unlikely) • PS: mid May - beg November • SPS: mid June – beg September • No longer (>1-2d) interruptions HCAL Main Meeting

  6. CERN preparations • In contact with • C. Rembser (Test beam Coordinator) • I.Efthymiopoulos (SPS NA beam lines scientist) • T.Camporesi offered support • Drafted beam request • Parasitic muon running July – August • 2 beam periods in September and October/November • 1.5 w ECAL, 1.5w HCAL, 2 weeks combined • Need to prepare proposal for SPSC (4-6 p, due end October) • Work on mechanical integration HCAL Main Meeting

  7. H6 beamline 5-100 GeV Electrons not bad H6 b (not full space shown) HCAL Main Meeting

  8. Integration • H6: currently no other user, but tight space requireemnts • H8 more spacious, tertiary (low E) beam, but other users K.Gadow, I.Efthymiopoulos Ongoing work HCAL Main Meeting

  9. Availability 2006 • Call for requests in September, schedule in November • Availability at present only educated guesswork • First months (mid June – end August): usage by LHC experiment • Later reduced demand, except • H4 (CMS ECAL calibration all year) • H2 (also CMS, up to September or longer) • Better prospects in H6, H8 • H8 has quite extensive cryogenic installations (ATLAS LAr) • H6 seems a good bet for September / October HCAL Main Meeting

  10. Prospects 2007 and beyond • Testbeams are foreseen for 2007. • Start not yet clear, possibly May • Later if LHC sector test (Nov 2006) postponed • CERN Gran Sasso neutrino beam (CNGS): 2 schemes: • Normal, maybe somewhat longer spill, longer break (~30s) • Or dedicated runs; would imply shorter testbeam period than 2006 • LHC (July 2007 onwards acc. to present planning) • No testbeams during LHC filling and set-up • Expect about 50% non-availability • Average, could be intervals of 15 min – or many hours • LHC has absolute priority • Should improve in 2008 with better routine operation HCAL Main Meeting

  11. FNAL • No news on bunch structure, but indicate flexibility and strong interest • Improvements in beam-line infrastructure underway • Start with TCMT in 2006 • Awaiting ECAL + HCAL in 2007 HCAL Main Meeting

  12. Conclusion • Prospects for commissioning and first data taking at CERN are ambitious, but not unreasonable • My view: go for it with whatever we will have next summer • Mechanical support plus n cassettes HCAL Main Meeting
