  1. Overview of PHENIX upgrades Goals of PHENIX upgrades program PHENIX upgrades at a glance detector systems and status physics reach of combined system new detector systems not covered today The FVTX and NCC proposals Submitted BNL to seek construction funds starting FY08 PHENIX internal review in December 2005

  2. requires highest AA luminosity Physics Beyond the Reach of PHENIX Provide key measurements so far inaccessible at RHIC in three broad areas: • High T QCD (AA, pA, and pp): • Electromagnetic radiation (e+e- pair continuum) • Heavy flavor (c- and b-production) • Jet tomography (high pT PID, jet-jet and g-jet) • Quarkonium(J/, ’ , c and (1s),(2s),(3s)) • Spin structure of the nucleon: • Gluon spin structure DG/G (heavy flavor and g-jet correlations) • Quark spin structure Dq/q (W-production) • Low x phenomena • gluon saturation in nuclei (particle production at forward rapidity) All measurements base on existing capabilities enhance by detector upgrades Axel Drees

  3. PHENIX Detector Upgrades at a Glance • Central arms: • Electron and Photon measurements • Electromagnetic calorimeter • Precision momentum determination • Hadron identification • Muon arms: • Muon • Identification • Momentum determination • Dalitz/conversion rejection(HBD) • Precision vertex tracking (VTX) PID (k,p,p) to 10 GeV (Aerogel/TOF) • High rate trigger (m trigger) • Precision vertex tracking (FVTX) • Electron and photon measurements • Muon arm acceptance (NCC) • Very forward (MPC) Axel Drees

  4. MPC south Preparing for HBD installation in April/May 2006 TOF west MRPC construction Installation 2006 Areogel completed 2005 PHENIX Detector Upgrades at a Glance • Central arms: • Electron and Photon measurements • Electromagnetic calorimeter • Precision momentum determination • Hadron identification • Muon arms: • Muon • Identification • Momentum determination • Dalitz/conversion rejection(HBD) • Precision vertex tracking (VTX) PID (k,p,p) to 10 GeV (Aerogel/TOF) • High rate trigger (m trigger) • Precision vertex tracking (FVTX) • Electron and photon measurements • Muon arm acceptance (NCC) • Very forward (MPC) Axel Drees

  5. Vertex Tracking (barrel and forward endcaps) Precision measurements of charm and bottom production Barrel (VTX) funded through RIKEN ($3M) and DOE ($4.6M), now in FY07 presidents budget Forward endcaps proposed to DOE (~$4.5M), reviewed today PHENIX Upgrades in Central Region • m trigger • W measurements in pp • ~$2M funded through NSF • Nose Cone Calorimeter • p0 and photon measurements • Proposed to DOE (~$4M), reviewed today • Hadron blind detector (HBD) • Reject Dalitz/Conversion electrons in electron pair measurement • Under construction funded through BNL, NSF, SBU, WI R3……...R2………..R1 HBD NCC VTX Axel Drees
