Chiho Wang ATLAS TRT Duke University CERN, Feb All modules installed! Feb. 3, 2005

Chiho Wang ATLAS TRT Duke University CERN, Feb Snap shot Feb. 8 snap shot  Type 1: u All modules installed & tested u All electronics installed u 20 modules cooling tube installed  Type 2: u All modules installed & tested u 18 side A electronics installed  Type 3: u All modules installed u 28 modules with protection boards and tested Feb. 06, 2005

Chiho Wang ATLAS TRT Duke University CERN, Feb Module installation time line 30 module mounting days

Chiho Wang ATLAS TRT Duke University CERN, Feb Module placement  Final dead wire distribution:  Type = 1.17%  Type 2 121=0.73%  Type =2.26%

Chiho Wang ATLAS TRT Duke University CERN, Feb Final dead wire distribution  Whole barrel: u 817 = 1.55%

Chiho Wang ATLAS TRT Duke University CERN, Feb Mechanical Assembly Processes

Chiho Wang ATLAS TRT Duke University CERN, Feb Module preparation (done, except for spares)  Capacitor installation (~1-2 days/module) u Insert capacitors u Check capacitor connectivity u Check HV traces u HV test: caps + wires u Seal capacitors  Pre-insertion prep. (6 modules/day/2 person) u Check ground wire u Check cooling sleeve u Check mounting holes u Active gas fittings, custom made for each module: connection & leak test u Glue purging gas gasket u Tape HV kapton for protection u Glue thermal sensors as needed (4 modules each type)

Chiho Wang ATLAS TRT Duke University CERN, Feb Module installation & tests (4 last modules)  Procedures & tests u Fold HV kapton and cover with protection plates u Insert module & fix one corner u Set module z position to middle of BSS u Fix module 2 nd corner & attach set screws u Check purging gas flow Type L/min < 10% loss Type L/min < 15% loss Type L/min < 20% loss u Unfold HV kapton & check HV traces u Attach & glue active gas fittings u Plug & seal unused active gas inlets. u Leak test active gas volume (1mB/B/min) u Install protection boards u HV test with Ar-CO2 u Check active gas path for obstruction (flow rate test)

Chiho Wang ATLAS TRT Duke University CERN, Feb Cooling lines installation (on going)  After the electronics have been: u Installed u Continuity check u Noise check  The cooling lines are: u inserted through both corners of the module u 90 bend forced on one end u Attachment to cooling plate at each end. u (T1 – 20 modules)  Cooling flow measurement is made. u (T1- 20 modules)

Chiho Wang ATLAS TRT Duke University CERN, Feb Module repairs & modifications  Components modification u Peek tubes for module cooling reduced from 0.123”-0.127”  0.116” ” (done) u Fuse box brackets dimension change u Fuse box screws changed from Nylon to Ultem u CO2 flushing tube redesigned with corrigated PEEK. u De-magnetized stainless steel screws for active gas inlet plugs (started from type 2 modules)  Module repair: u Wire removal (2 bad wires + some retroactive decisions from acceptance group) u HV trace broken, shares from neighboring line (1) u Cooling sleeve replacement (4) u Three wires removed from BSS. (2 drawing excess current, 1 shorted). u Two modules (T1) show a connection between 2 signal wires (double joints) at one end. Left for now.

Chiho Wang ATLAS TRT Duke University CERN, Feb Remaining mechanical work  Finish testing the last 4 type 3 modules (~1week)  Continue to install module cooling tubes as electronics are installed  Install outer cylinder u After all modules are tested (~ March, ~1week) u Before manifold can be installed  Install services after electronics are installed u Cooling manifold (contract, deliver ~ April) u Active gas manifold (drawing/review ~ this week) u Purging gas manifold (parts)  Install fuse boxes u Need to solve fuse problem and resume production u 3 possible windows for installation (in descending preferences) Before TRT/SCT system test ~ Oct. Before going in the pit ~ Feb. 06 In the pit, same time as harness or before (?)  MTF migration: Data base structure defined, entering data.

Chiho Wang ATLAS TRT Duke University CERN, Feb Electronics installation  Type 1: u Completed Jan. 24, 2005  Type 2: u Side A (2B): 18 modules installed 22 boards in repair process, ~ 10 finished u Side C (2F): started stuffing at ACAMAS. Should have pre- series at CERN ~end of Feb.  Type 3: u Side A (3B): Pre-series at CERN and tested. Feedback to ACAMAS. No known issue. u Side C (3F): All bare board received. Need to start pre- series.

Chiho Wang ATLAS TRT Duke University CERN, Feb Electronics schedule  3B will be the next to arrive (followed by 2F and 3F) and available for installation ~April 11.  After that we will be saturated with boards.  Installation is the slowest part. u 3 weeks per side for type 2 u 1 month per side for type 3  Will need to run more than one shift to finish installation in June.
