  1. Summary of Si Strip Group QA Preparation& Schedule and Costs Abhay Deshpande Stony Brook University PHENIX VTX Detector Readiness Review Brookhaven National Laboratory January 19, 2005

  2. Overview • You heard about the • Strip Sensor from J. Tojo (RIKEN) • Front End Electronics from V. Cianciolo (ORNL) • This talk will cover • Plans for Q/A for Si Strip Sensors • Status of Three facilities: BNL, UNM and SBU • Plans for assembly and tests for ladders onwards • Collaboration: RIKEN, SBU, BNL-Chemistry • Schedule & Costs • Manpower for Q/A Abhay.Deshpande@StonyBrook.Edu

  3. QA & Assembly Plan • Sensor QA • Preproduction of Hamamatsu/SINTEF wafers: • Resistance, doping tests, diced in to Sensors • 400 sensors start arriving BNL/RBRC Mid 2005 • Registration, visual inspection • Divide them up in to three sets SBU, UNM, RBRC/BNL • 1 or 2 wafers/day/site • Current, Capacitance at full depletion Voltage • Inter-strip current & capacitance (x-x, u-u, and a few x-u) • Assembly of ladders and QA • ROC+Sensor (SBU/RIKEN) • Glue (6-8 hrs) + wire-bond (2 hrs) + test (1 hr) • Ladder (5 ot 6 ROC+Sensors) (SBU/RIKEN) • Glue + wire-bond (1 hrs) + test (1 hr) • First one taken for bench & beam test, next only bench tests • Construction of the barrel: BNL Chemistry/PHENIX Abhay.Deshpande@StonyBrook.Edu

  4. Laboratory Setups and Status • RBRC/BNL • Laboratory setup in the last three months • Semi-Automatic probe station moved from instrumentation division and added equipment peripherals • Activity started, fully functional facility • Stony Brook University • Stony Brook high energy physics facility for D0 to be given to PHENIX for 2-3 years starting Jan/Feb 2005 • Fully functional with clean room, semi-automatic probe station and peripheral; plans to add bonding machine with off project funds • University of New Mexico • UNM high energy physics CDF facility to be used for PHENIX SVTX QA, fully equipped, software being installed and tested. Fully functional in the next few days/weeks Abhay.Deshpande@StonyBrook.Edu

  5. New RBRC/BNL Laboratory Setup Abhay.Deshpande@StonyBrook.Edu

  6. What is where in this lab? New clean room at BNL The condition in the dark box is almost; temp: 25[oC] hum : 15[%] Semi-automatic probe station in the dark box Keithley 7002 switching system Wafer in the desiccators N2 gas for desiccators PC for DAQ PC for Analysis HP 4263B LCR meter Fitting room Keithley 6487 HV/Ammeter The new clean room was setup at RBRC lab. room 2-205 in BNL in this October.

Ribbon Cable Probe positioner for Guard Ring Probe card Probe stage HV/Ammeter Keithley 6487 Windows LabView sensor chuck Movable stage LCR Meter Agilent 4263B Switch system Keithley 7002 Probe station Abhay.Deshpande@StonyBrook.Edu

  9. QA guidelines & criteria • Mechanical properties: dimensions, thickness, widths, edge chipping, alignment of various components including metallization points etc. • UNM,SBU already have facilities that do this • Electrical properties: CV, IV curves, leakage current on strips, inter-strip resistance, inter strip capacitance) • Key tests (every sensor, every ladder) • Subset tests (defined fraction of sensors and ladders) Laser/source and observe basic response, CV/IV 1 u/x per active area (4 per sensor) • Diagnostic tests: to be performed on sensor/ladders tagged for some abnormality • All data to be stored in a dedicated database presently being produced by P. Steinberg et al (BNL/Chemistry) • Extensive experience from PHOBOS will be preserved! Abhay.Deshpande@StonyBrook.Edu

  10. Strip Sensor Presently [here] ==> Jan-Mar’05 QA of preproduction ==> Decision ==>Production Sensors Arrive (7/19/05) ==> divide 400 in to 3 sets and ship to QA sites. ==> Three months for QA (130 wafers : 2 wafers/day = 65 days ~25 days contingency (38%) but that too is an under estimate since we need only 246 wafers as against 400 assumed in this calculation and real start date may be much earlier than the presumed (1/2/06). Abhay.Deshpande@StonyBrook.Edu

  11. Strip Sensor Budget • Most of the work performed by students/post docs so no manpower cost to project. • Assume $2500/month for materials costs in laboratories, times 3 months + BNL overhead + 50% DOE contingency = TPC DOE Abhay.Deshpande@StonyBrook.Edu

  12. Strip System Tests Presently [here] ==> next year for ROC+Sensor “module” development ==> start assembly of ladders for testing Oct’05 and continue until Oct.’06 Abhay.Deshpande@StonyBrook.Edu

  13. Strip System Test Budget • TPC DOE = (Man-hour estimates + Material costs + BNL overhead) + 50% DOE • contingency. • Most work will be done by the post docs and students (see list later) • Man-hour cost estimate: depends on technician help or engineering help • Material cost $1500/ month times number of months Abhay.Deshpande@StonyBrook.Edu

  14. Strip Ladder Assembly Abhay.Deshpande@StonyBrook.Edu

  15. Strip Ladder Assembly Budget • 9 months of a technician assumed 5k/month • Material costs: setting up of jigs, and later test equipment: engineering estimate • TPC DOE = (Manpower + material cost + BNL overhead) + 50% DOE Contingency Abhay.Deshpande@StonyBrook.Edu

  16. Summary: FTEs, Cost & Contingencies • All FTE-weeks calculated with 30-45% time contingencies • Slide 10 ==> 60 FTE-weeks • Slide 12 ==> 84 FTE-weeks • Slide 14 ==> 224 FTE-weeks • Total FTE-weeks for this part of the project: 368 • Most of this work will be done by Physicists (students/post docs) • DOE Total Project Costs for this part of the project = BNL overhead + (additional overhead if applicable) + 50% DOE contingencies • Total Project Cost (TPC) for this part of the project is: $343,478 = $88,750 (manpower) + $141,322 (material + overhead) + $113,406 (~50% contingency) Abhay.Deshpande@StonyBrook.Edu

  17. Person-power: QA, assembly & tests • Stony Brook University • Grad Students: K. Boyle, R. Bennett, S. Campbell , A. Dion, M. Nguyen, H. Themann, and more expected in future • Post Doc to be appointed + J. Franz • Technical/Electrical/Electronics: R. Hutter, C. Pancake, E. Shafto • Faculty: A. Deshpande, A. Drees, V. Pantuyev • RIKEN-BNL Research Center at BNL • Post Doc: J. Asai • Scientist: J. Tojo, Y. Goto, A. Taketani, Y. Akiba • BNL Chemistry • Scientsts: R. Noucier, R. Pak, P. Steinberg, M. Baker, B. Holzman, A. Sukhanov • Post Doc: Z.W. Chai • University of New Mexico • Graduate students: R. Hobbs + future students • Technical: M. Hoeferkamp • Faculty: D. Fields All Off Project!
