4. 28/4/2004 16th RRB J. Schukraft 4 Funding Issues US participation ~ 10 M$: EMCAL for jet physics  NSAC sub committee on US heavy ion program (GSI/RHIC/LHC)  final report October 2004 with positive recommendation for LHC  proposals exist from ALICE, Atlas and CMS Japan & China  Japanese participation (~ 10 M$): TRD, PHOS  proposal not funded in 2004, may be resubmitted end 2004  Chinese participation (~ 3 MSF): PHOS  proposal now to be submitted to MoST & MoE (no longer NSFC)  Consequences for PHOS  with the resources available we will be able to built only 3 modules  1 ready for installation in 2006/2007/2008 each.. The LHC will open up a new regime in relativistic heavy-ion physics with significant opportunities for new discoveries. The Subcommittee recommends that: Participation at the LHC should become a new component of the U.S. Heavy-Ion program. This participation should receive comparable investment priority with each of the near-term upgrade programs for the two large RHIC detectors.
