(usually the angle between sensors exceeds spec slightly)

3. Tracker Outer Barrel- October 26, 2005 – Tracker General Meeting slide 3 Module Assembly Planning FNAL: Last week increased to 15 TOB modules/day. Storage capacity is very tight Summary tables can be viewed at http://cmsdb.fnal.gov.http://cmsdb.fnal.gov November: ramp to 18 TOB modules/day. Goal: Finish TOB modules end of January Need to understand quantity of spares to be built. Then: Transition to TEC R7 Rod assembly will continue through April. UCSB Last week 18 modules/day This week 21 modules/day Also to do: bias connections on some 1,400 modules. Wire bonding and ARCS operations (but not LT).

4. Tracker Outer Barrel- October 26, 2005 – Tracker General Meeting slide 4 FNAL Plans for TEC Production FNAL preparing to build ~700 TEC R7 modules Beginning early next year. The UCSB R7 Gantry assembly plate design has been modified for use on the FNAL Gantry expect first of 6 assembly plates by end of year. Other fixtures and plates – for hybrid testing, hybrid and module bonding, storage and shipping – will be constructed from existing designs. Once established, production will take about 10 weeks. FNAL plans closer contact with the TEC community. At some point it would be helpful to receive some non-qualified or spare sensors, hybrids, and frames for R7 modules.

5. Tracker Outer Barrel- October 26, 2005 – Tracker General Meeting slide 5 Module Bias Connections Solder gold-kapton extension tabs to unused vias on TOB frames. Glued down with TRD 1100 (Ag Epoxy following (during) Gantry assembly at FNAL (UCSB) Then wirebond to backplanes (15 bonds per sensor) Bonds encapsulated with Sylgard 186 The application of silver epoxy (single drop) and scratching of sensor backplanes as part of the traditional Gantry assembly is unchanged.

6. Tracker Outer Barrel- October 26, 2005 – Tracker General Meeting slide 6 Existing Module Bias Connections Plan to use an insulated wire for some already fabricated modules. Wire is connected to a gold-kapton tab that spans the two sensors. Some 1400 modules may require this modification FNAL expanding work force to retrofit 24 modules/day.

7. Tracker Outer Barrel- October 26, 2005 – Tracker General Meeting slide 7 Bias bond encapsulation For the detailed procedure see: http://hep.ucsb.edu/cms/cms_procedures/tec-encapsulation-procedure.pdf For the drawings of UCSB designed tools see: http://hep.ucsb.edu/cms/mechanical.html A talk describing the procedures is available from the bonding working group agenda this week,.

8. Tracker Outer Barrel- October 26, 2005 – Tracker General Meeting slide 8 US Module Storage Delays in rod and pedal assembly have made module storage a critical issue and UCSB and FNAL. TEC modules: 4 more boxes are being built at UCSB to help alleviate the problem. (~20 are available for shipping currently) It is critical that boxes received in Europe are unloaded and returned to UCSB. TOB modules: ~2800 modules currently in storage at UCSB and FNAL New storage capacity for roughly 1000 more by the end of the month. This includes building module storage plates. (Recently built 1300). More may have to be fabricated.

18. Test modules with fully functional ARCS and LT test stand Visually check modules with shorts / pinholes etc. Sometimes I2C FEC error occurs during LT run - possibly due to inadequate shielding of the cables. To be sorted out soon Developing a probe station that can troubleshoot bad hybrids at low Temps Received some bad modules/hybrids from Fermilab & UCSB to test and understand problems. Troubleshooting them now. Work Done Work in Progress Future plans Riverside Repair Center

19. Tracker Outer Barrel- October 26, 2005 – Tracker General Meeting slide 19 Rod Status - UCSB and FNAL In the past couple of weeks, while waiting for ICC cards to start production, the two sites have focused on slightly different issues FNAL: testing of new SW (FEC V3, Scientific Linux, Lt V30) UCSB: production exercise to shake down remaining operational issues Fine-tuned scenario to match 4 rods/day rate Freezer takes max 8 SS4, 6 SS6, 4 DS  need one day scenario (so much for long term  ) Only two thermal cycles W  C  W  C  W CalProfRuns only with inverter-on to save time Added HV cycling at each temperature This is not working reliably, may have to ditch

20. Tracker Outer Barrel- October 26, 2005 – Tracker General Meeting slide 20 General 4 sets (2/site) of OFECs in transit from CERN FNAL will "commission" this system first; UCSB will follow when it works First batch of ICC cards for 25 rods also in transit ½ FNAL, ½ UCSB Will mount on existing rods, then put modules on rods, then test, then ship. ASAP

21. Tracker Outer Barrel- October 26, 2005 – Tracker General Meeting slide 21 FNAL Status (1) Over 30 production scenarios run on MRT since July 2005 50 SS6 rods and four DS4 rods were assembled (using jumpers on pre-production ICC cards), tested and burned-in Migration of rod test software running on Red Hat Linux 7.3 with FEC Software V1 to Scientific Linux 3.0.5 with FEC software V3 was successful Long term testing with latest release of the FEC Software showed good stability of software and the control ring (1 upload/download error in 24 hours with 4 DS4 rods) Latest release of the LtStruct (v30) was extensively tested with a number of production scenarios with Single Sided and Double Sided rods

22. Tracker Outer Barrel- October 26, 2005 – Tracker General Meeting slide 22 FNAL Status (2) First batch of 12 new (production grade) ICC cards were shipped from CERN to FNAL and are expected to arrive this week Plan for assembling of the first 12 production rods has been prepared Optical FECs are expected to arrive this week. Test stands will be upgraded and tested with new hardware while the first production rods are assembled We will need new rod frames to arrive not later than the second shipment of production ICC cards

23. Tracker Outer Barrel- October 26, 2005 – Tracker General Meeting slide 23 UCSB Production Exercise: Mechanical Built 24 rods last week (22 SS6, 2 DS) Warmup 1st two days, then built 4 rods/day Bottom line: OK Some Issues: Dirty rod boxes, Al dust Will tape lips of boxes with kapton tape, avoid friction, dust All boxes will be in plastic sleeve for shipping Need to understand desiccants Tail bending a la FNAL: OK. ICC cards swap: adds 20-30 minutes/rod DS rods: worry about exposed non-encapsulated bonds Now designing a cover with cutouts for ICC cards. Will enable handling of connectors and cables with minimal risk of smashing bonds

24. Tracker Outer Barrel- October 26, 2005 – Tracker General Meeting slide 24 UCSB Production Exercise: Testing 20/24 rods through SRT Mounted some modules with known pinholes Flagged them without a problem 1st MRT scenario OK, 2nd failed Failure in newly introduced HV cycle. CAEN got stuck. Not a new problem. A couple of laser failures (?) – Very worrisome… Some noise oddities to be investigated Some ICC/header errors. Hopefully will be better with new SW, new OFEC (Almost) successful 1st upload of rod XML file to DB Need some small name changes

25. Tracker Outer Barrel- October 26, 2005 – Tracker General Meeting slide 25 UCSB Production Exercise: Short Term Plans Stop making rods We learned what we needed to learn Continue exercising testing cycle

26. Tracker Outer Barrel- October 26, 2005 – Tracker General Meeting slide 26 TOB Integration Procedure  being tested with pilot cooling segment Rod insertion: ~30-60 min x N rods Functional test per control loop [could be dropped at some point?] Solder cooling connections per rod: ~30-60 min x N rods He leak test per cooling loop Dress cables, Dbase entries etc…: ~30-60 min x N rods DAQ test per control loop Initially: N = 1 cooling segment. Once confident: N = 1 layer. Organization Ramp up to 7-day 24-hour operation Two 3-person tech shifts per day (3 crews of 3 for 7-day coverage) Two testing crews covering night shifts 1st Tech crew now in place, 2nd one identified for Dec, will need 3rd in Jan Once operation is smooth may be able to add 1 tech per crew and work on both ends of TOB Schedule: Ramp up Dec+Jan, complete by May estimate should improve after experience with pilot segment

27. Tracker Outer Barrel- October 26, 2005 – Tracker General Meeting slide 27 TOB Cooling Segments

28. Tracker Outer Barrel- October 26, 2005 – Tracker General Meeting slide 28 Pilot Integration Test Purpose Primary: Test the procedures and fixtures, and guide any improvements Secondary: Confirm staffing plan and improve schedule estimate Plan Use Rods with old IC cards Install and test 19 rods in the top segment of layer 6- Remove them again (confirm our ability to replace rods after insertion) Status All 19 rods have been inserted (17 by technician crew) A first round of tweaks were made to the fixturing, further improvements to aid efficiency are under discussion A test of soldering the cooling line connections using a single rod was successful Next steps are to connect and test the cooling for the 19 rods this week, and to start electrical testing next week Expect to be ready to start integration with final rods by end Nov Need to design/build the work platform for installation of layers 1-5 inside TST – platform is not trivial, will be needed by January
