  1. Overview of VTX Strip Group Activities Abhay Deshpande SUNY-SB For Si Strip Group Si VTX Strip Overview

  2. Active Sub-Groups R&D Ongoing • Junji/Atsushi et al. RIKEN • Vince et al. ORNL • Doug/Martin et al. UNM • Kieran/Junkichi et al. BNL/SBU Testing Facilities Getting Ready Si VTX Strip Overview

  3. A.D. & J.T. February04 1 day meeting RIKEN-ORNL Activities • Stripixel sensor development • The 1st prototype fabricated and tested • Expected position resolutions. • S/N and charge sharing property is needed to be improved. • The 2nd prototype fabricated • Finer stripixel structure. • Charge sharing property is expected to be improved. • S/N will be tested with SVX4 by April 2004. • Test production in SINTEF and Hamamatsu under development. • Sensor + SVX4 chip (+AC coupling) test by Apr. 2004. • SVX4 readout board development done by the end of Feb. • ROC (w/ SVX4s) prototype by Oct. 2004. • Sensor + ROC tests by the end of 2004. • Ladder test by the middle of 2005. Si VTX Strip Overview

  4. Status of Test Wafers from CNTF and HMMTS • CNTF wafers (17) arrived at RIKEN last week • To be sent to BNL and UNM for testing • 1 at RIKEN, 8 at BNL/SBU and 8 at UNM • Presently to confirming adequate storage capacity at UNM and BNL (see Junji’s slides) • HMMTS wafers expected by the end of September 2004 • To be sent out for testing to BNL and UNM • Both are on schedule Si VTX Strip Overview

  5. UNM Ready End of September’04 • Probe card and testing facility (probe station) is ready to start doing measurements as soon as they get: • Pico-ammeter, voltmeter etc. etc. etc. • Atsushi will send them to UNM from RIKEN in the coming week • Likely that UNM ready and will start doing test measurements by End of September 2004 Si VTX Strip Overview

  6. BNL/SBU not quite ready, but.. Will be Mid-End October’04 • Kieran + Junkichi are testing setup in the Instrumentation lab with the semi-automatic probe station (details in Junkichi’s talk) • Comparison of manual vs. semi-automatic probe station on wafers with Cone design (spiral design for future) • That facility is planned to move to RBRC/205 lab for about 1 year or so (until SBU lab becomes available) for us to do the test production wafer testing. • Plan to get the BNL/RBRC facility ready by Mid-End of October (~2-3 week delayed) • Details and reasons follow…. Si VTX Strip Overview

  7. The plan A --> B • Appx. 1/3 of RBRC 205 lab to converted in to a clean room • Kieran, Junkichi, Yuji, Rich Hutter (SBU), Atsushi & Abhay made initial plans • Cleanliness needed, needed asked for estimates for cost of emptying, cleaning 2-205 and setting up clean room • BNL: union estimate came 1.5 months late and WAY beyond our limits (time wasted!) • Plan B is in progress and will be ready in about 5-6 weeks (from now) Si VTX Strip Overview

  8. The plan B…(cont) • To order from Clean Air Products Series 577 vertical flow soft-wall modular clean room • 12 ft x 12 ft x 8.6 ft • Class 100 • Internal filters, lighting etc. etc. • Delivery 2 weeks, Cost about $14.0k • Ordered the cleaning of the ceiling in 2-205 will take 1 day, order pending for 4-5 weeks. • Safer solution with cheaper option of the clean room • We should be ready to go by October (mid-end) 2004 Si VTX Strip Overview

  9. SBU plans on track: • SBU-HEP group getting ready for their tests • We will contribute and learn • Si Lab with the probe station for PHENIX by Spring 05 as expected • Movement on finding a Bonding Machine • Rich & Abhay: K&S 8060 (identical to RIKEN’s new purchase) got the initial quote • Supporting letter from PHENIX vtx group --> PHENIX --> would be requested soon (this or next week) • AD will approach funding sources local, details to be finalized as soon as PHENIX VTX group makes their statement clear: that we would want it. • In future to be included along with the Semi-Automatic probe station as a complete Si lab facility at SBU dedicated to PHENIX and D0 Si VTX Strip Overview
