Activities in ALICE Daicui Zhou (for the Chinese Team) Brief Review on High Energy Heavy-Ion Physics in China Activities in ALICE Further Plan Expectations Summary The Goals of High Energy Heavy-Ion Collisions To search for a new form of matter － QGP (deconfinement and chiral symmetry restoration) To explore the phase diagram of QCD matter New physics at TeV energies, e.g. CGC, exotic particles, etc. To give indication to the origin and evolution of the universe Brief Review on Chinese Participation in High Energy Heavy-Ion Experiments AGS/SPS/JINR programs (1986-2000): ?s=1.9GeV~17GeV EMU01(1986): 3 Institutes, (IHEP, SXNU, CCNU) E815(1986): 3 Institutes (IHEP, SXNU, CCNU) EMU12 (1991): 4 Inst., 20 people (IHEP, Hunan U., SXNU, CCNU) E863 (1990): (CCNU) NA49 (1996-1999) (CCNU) RHIC program (1999-) ?s=62.4GeV~200GeV PHENIX: 1 Institute, ~ 5 people (CIAE, PKU) STAR: 6 Institutes, ~ 50 people (USTC, Tsinghua U,. SINR, IHEP, CCNU, IMP Lanzhou) (MRPC-TOF detector) LHC program (1993-) ?s=5.5TeV ALICE : 3 Institutes, ~ 30 people (CIAE, CCNU, HUST) (Photon Spectrometer) In addition, as individual there are many people worked or working on experiments such as: NA50, NA60, PHENIX, BRAHMS Activities in ALICE Research Activities and Achievements 1999-2001 RD PIN-Diodes (successfully passed the beam test) 1999-2002 RD PHOS Mechanics and production scheme 2002-2003 DAQ system for PHOS beam test 2002-2004 RD Preamplifier 2004 PC Farm (26 nodes, 2.8GHz double CPUs,7TBytes) 2002-2005 PHOS FEE (design, layout, manufacturing, testing in Wuhan and CERN for 12 FEEs ) 1995-2005 MC study on ALICE/PHOS (Punch-through Effect, PHOS PID, Trigger Efficiency, ?0 reconstruction, Di-muon invaria
