  1. Creighton UniversityALICE - USA Michael Cherney May 23, 2007

  2. Creighton and ALICE • Slow controls presentation at ALICE • September, 2001 • Membership in ALICE • Offered Fall 2001 • Accepted Fall 2002 • Primary Source of Funding • DOE EPSCoR

  3. Contributions to ALICE • Hardware Controls • Controls Infrastructure • ITS Alignment System Controls • EMC Hardware Controls • Physics • EMC Jet Triggering Studies • Christopher Anson, MS Thesis (2006) • UPC Triggering

  4. Commitments to STAR • Hardware Controls • Responsible for Controls • Moving Majority of the System from VME to PC’s • Integration of Upgrade Subsystems • On-Site Expert during Setup and Run • Physics • UPC Physics • Convener - Janet Seger • Rho Production • J/psi Production • Giant Dipole Resonances • D* production in pp collisions

  5. Commitments to Outreach • Cosmic Rays • High School Students • CROP Network • Introductory Students • Nuclear Science Introduction • Gifted Middle School Students • Gifted High School Students • Boy Scouts

  6. Creighton Staff • Faculty • Michael Cherney (DOE summer support) • Janet Seger (DOE summer support) • Thomas McShane • Permanent Staff • Jiro Fujita (Computing Support) • Brad Walters (Machinist) • Postdocs • Yury Gorbunov (DOE support) • William Waggoner (DOE support)

  7. Students • Graduate Students • Kimberly Kirchner (DOE support) • Lyle Sass • Eric Watson • Undergraduate Students • Abbie Bauer • Matt Brnicky • Jennie Burns • Joseph Butterworth (DOE support) • Robert Thomen • Kristen Wakin (DOE summer support)

  8. Expected Changes in Funding • EPSCoR funding will end in December • Expected changes in manpower • Currently 2 postdocs (2.0 grant-funded FTE) • Expected 1 postdoc (1.0 grant-funded FTE) and 1 permanent staff (0.2 university-funded FTE) • Reduction in outreach effort • Keep research efforts at same level

  9. Projected Effort • Current Distribution of Effort • STAR 4.1 FTE • ALICE 1.8 FTE • Outreach 1.9 FTE • Proposed Distribution of Effort • STAR 4.1 FTE • ALICE 1.8 FTE • Outreach 1.1 FTE

  10. UPC Physics at ALICE • Field is Lorentz contracted • GSI  = 1 electrons • RHIC  = 200 rhos • LHC  = 5500 heavy flavors • Much larger energy density • u = ½ 0 E2 • Production is limited by coherence • Some more massive particles • Many less massive particles • Experiment is leading theory Joackim Nystrand

  11. J/psi Production in UPC’s J/mass spectrum from a month of running at ALICE J/ mass spectrum from a month of running at STAR • Full ALICE simulation done • Trigger studies presented at October ALICE meeting Preliminary Inv. Mass EMC has value in tagging electrons

  12. UPC measurements of Rho •  cross section as a function of energy • Expected to be 10x greater than at RHIC •  incoherent vs. coherent production • Straight forward Day 1 measurement which does not require pid • Comes almost “at no cost” as background in other measurements

  13. Upsilon Production in UPC’s Simulated Reconstruction of Muon Signal Simulated Reconstruction of TPC Acceptance for Muons Simulated Reconstruction of TPC Acceptance for Muons Simulated Reconstruction of Electron Signal Simulated Reconstruction of TPC Acceptance for Electrons Simulated Reconstruction of TPC Acceptance for Electrons

  14. Slow Controls for ITS • Laser Alignment System • With The Ohio State University

  15. EMC Controls

  16. EMC Control – High Voltage • Test System at CERN (Summer 2006)

  17. EMC Controls - RCU • Test System at BNL (Summer 2006)

  18. EMC Controls - Temperature • Test System at Creighton

  19. Summary • Returning to Pre-EPSCoR Funding • Seeking Blessing for Continuing Present Program • Controls • Ultra-Peripheral Collisions • Seeking Blessing for Continuing Present Division of Experimental Effort • STAR (70% of experimental work) • ALICE (30% of experimental work) • Outreach will be impacted
