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

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

January 19, 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

January 19, 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

January 19, New RBRC/BNL Laboratory Setup

January 19, What is where in this lab? New clean room at BNL The new clean room was setup at RBRC lab. room in BNL in this October. Fitting room Wafer in the desiccators Semi-automatic probe station in the dark box PC for DAQ PC for Analysis N2 gas for desiccators Keithley 7002 switching system HP 4263B LCR meter Keithley 6487 HV/Ammeter The condition in the dark box is almost; temp: 25[oC] hum : 15[%]

January 19, Semi-Automatic Probe Station Ribbon Cable GPIB Cable Probe station HV/Ammeter Keithley 6487 Switch system Keithley 7002 LCR Meter Agilent 4263B Windows LabView Windows LabView controlled All device through GPIB cable. Dark Box Microscope Movable stage chuck Probe positioner for Guard Ring Probe card sensor Probe stage

January 19, SINTEF measurements at RBRC/BNL Good x strip Bad u strip Good u strip

January 19, 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!

January 19, 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).

January 19, 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

January 19, 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

January 19, 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

January 19, Strip Ladder Assembly

January 19, 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

January 19, 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)
