4. Chiho Wang ATLAS TRT Duke University Dubna, May 2005 4 25/03/05 Heater pads installed  Almost! u 2 faulty pads not installed.

5. Chiho Wang ATLAS TRT Duke University Dubna, May 2005 5 Electronics  More than ½ boards installed. Hear more from Ben…

6. Chiho Wang ATLAS TRT Duke University Dubna, May 2005 6 Remaining tasks  Continue to install electronics and module cooling tubes.  Solder RF shield tape between outer cylinder and space frame.  Install manifolds by quadrants after electronics are installed u Cooling manifold (~ June) u Active gas manifold (~June) u Purging gas manifold (in hand)  Install thermal sensors u Module/cylinder sensors: installed, connectors to be molded. u Cooling plate sensors: in SR. u Purging gas sensors: in SR(?). Attachment method to be worked out. u All wire length known.  Sector test: last (or first!) screening on a final assembled detector: u Cooling, active gas, purging gas, HV, thermal sensors, electronics … (except fuse boxes) u Some DCS modifications in progress.  Install fuse boxes u Production and evaluation will go in parallel.  MTF migration: Commissioning, entering data. https://edms.cern.ch/cedar/plsql/edmsatlas.home

7. Chiho Wang ATLAS TRT Duke University Dubna, May 2005 7 Summary  Manifold and electronics are in critical path.  Fuse box problem need to be solved.  We are almost there!
