Roma, Riunione CSN1: Maggio 2004F. Bedeschi, INFN-Pisa 3/13 Design and Base Projections We are here

Roma, Riunione CSN1: Maggio 2004F. Bedeschi, INFN-Pisa 4/13 TeV Luminosity (current situation)  Peak luminosity  Best 7.0 x10 31 !!!  Delivered/on tape  500/400 pb -1 /~100 bad due to COT  Analyses use data till Feb. 04  ~ 240 pb -1 > 2 x Run 1 Delivered On tape Integrated Luminosity Initial Instantaneous Luminosity 7 x Luminosity vs. time

Roma, Riunione CSN1: Maggio 2004F. Bedeschi, INFN-Pisa 5/13 Startup luminosity  Current delivered luminosity is exceeding design goals Design Base

Roma, Riunione CSN1: Maggio 2004F. Bedeschi, INFN-Pisa 6/13 COT problem  COT is experiencing an unexpected gain loss ~ 20%/yr  Chamber is currently operating at strongly reduced gain to prevent further damage New wire SL 2 wire now

Roma, Riunione CSN1: Maggio 2004F. Bedeschi, INFN-Pisa 7/13 COT problem  Chamber expected to be very radiation hard  Expected currents on SL1 is 4.5 L = 2x10 32 From 0.15 Coul/cm (2 fb -1 ) to 0.60 Coul/cm (8 fb -1 ) Predict < 1% gain loss at 1 Coul/cm  no problem …..

Roma, Riunione CSN1: Maggio 2004F. Bedeschi, INFN-Pisa 8/13 COT problem  Observations and diagnosis:  Gain loss has z and phi dependence  Reversing gas flow reverses pattern of damage  Damage most likely caused by insufficient gas flow  Actions taken:  Implement gas re-circulation system (80% re-circulated) Old flow 20 SCF/hr  40  200 testing effectiveness now Can push as high as 1000 SCF/hr this summer  Back up plans:  Increase operating temperature 72  82 F  Change gas Ar-CO 2 (or even CF 4 ?)

Roma, Riunione CSN1: Maggio 2004F. Bedeschi, INFN-Pisa 9/13 Trigger status  Continuously update to deal with higher luminosity  December 2003: 10kHz, 300Hz, 55Hz had ~25% deadtime L1: improve prescales and XFT L2: cut on muons, faster code, SVT fast abort L3: 64 more CPU’s, faster code  Now: L1/L2/L3 can run at 20kHz, 350Hz, 60Hz with low dead time, but…  SVT is dropped beyond 6x10 31 ….. Faster SVX readout Road Warrior (mostly Italian work) to remove ghost track before fitters SVT upgrade

Roma, Riunione CSN1: Maggio 2004F. Bedeschi, INFN-Pisa 10/13 Status CPR  M&S:  PO’s completed  ~ All material at Fermilab  Module production started  2 modules finished  Italian techs at work  HV work in progress  Cables and patch panels  Control and monitor software  Timeline:  Installation starts September 04  Module construction ends in July

Roma, Riunione CSN1: Maggio 2004F. Bedeschi, INFN-Pisa 11/13 Status CPR  Performance of first two modules as expected  Production at full speed 16 pe/MIP after full optical path Source scan

Roma, Riunione CSN1: Maggio 2004F. Bedeschi, INFN-Pisa 12/13 Status SVT upgrade  Prototype AM Chip design ready for production  Bid approval by INFN delayed  Hope to get into end of June slot at UMC Chips back in 3 mo  Plan for production in early 2005  With real design less patterns/chip  more chips needed  Additional cost is 40 k€ on FY2005  Long range plans of SVT upgrade being made at CDF  Even more chips may be needed, but with additional out side contributions

Roma, Riunione CSN1: Maggio 2004F. Bedeschi, INFN-Pisa 13/13 MOF  History:  250 k€ requested at September 2003 CSN1 meeting Referees favorable, but only 150 k€ assigned  INFN rep. promised 300 k$ = 250 k€ at IFC meeting in October 2003  150 k€ already spent and accounted for  Plan for use of additional 100 k€ already discussed with Fermilab Mostly help on unexpected COT costs  Request:  100 k€ now to complete FY2004 running cost contributions  Contributions to computing separate  Discussed in Belforte’s presentation

Bedeschi, INFN-Pisa 15/13 Tev 2003 Luminosity  Goals for 2003  Base goals: 200 pb -1 in FY pb -1 /wk end of x10 31 typical  Stretch goals: 320 pb -1 in FY pb -1 /wk end of x10 31 typical (~max achievable without Recycler)  Integrated luminosity goal achieved, but … Half of shutdown in FY04 Avg. lum. lower than predicted  FY04: Double data set ~150 pb -1 As of 5/6/03 ~250 pb -1 As of 9/3/03 back
