  24. Summary • Readiness of all systems • Response on change requests from ESR in September • QA/QC, including test during and after installation with requests of necessary infrastructure TOTEM T1 Readiness Review, 30 November 2010

  25. Requests (1) • The committee recommends contacting the CMS integration office for a ground point onto YE2, YE3, and perhaps onto the HF platform. Dmitry should be involved since this is rather a mechanical issue. • I propose to drill the threaded holes on inner radial surface of "YE4 inner disks" with 30 mm offset from its edge. The holes should be on 3 o'clock and 9 o'clock for both EndCaps. (Dmitry) • Each ¼ T1 have a main grounding ribbon running the length of the support frame. The ribbon is copper, 200 microns thick and approximately 10 cm wide. (also by Sergei) • Exteriors of CSCs connected with copper foil (also by Sergei) • In addition the aluminum support structure electrical continuity have been reinforced with copper braid or thick wires.

  27. Requests (2) • The committee endorses the insertion of fuses to protect 1.5mm2 power cables between the LV power supply and the 6th frame. It is important to explore the failure modes with the inline fuses in conjunction with remote sensing. Consider to add remote monitoring of the fuses for trouble shooting. Make sure that any additional work on the – side gets into the site planning. • Request of installing fuses on each electronics card triggered a complete redesign of the LV distribution on the detector. • Two x 4 LV distribution boxes (on T1 and at the MARATON output) • New cables on YE3 to connect the LV boxes • One fuse on each line at the MARATON output. Status of fuses is available locally and remotely through DCS. • One x 4 LVsense box (at the MARATON input) • Additional work on –side already planned within the schedule.

  37. Installation test and infrastructure • CHECKS on the system are foreseen when in the cavern • They are programmed in the last phases of installation: • Before insertion in the end cap • After the insertion in the end cap and before moving HF on 4 risers • The system check needs the LV, HV, R/O and DCS/DSS connections. • This in turns requires: • DCS running • Power for LV racks • S4 F05 (rectifiers) EXD 20/55 (breakers) • Power in TOTEM racks • S2 B03 (HV) S2 B02 (DCS) • DAQ-Data DAQ-Trigger TOTEM T1 Readiness Review, 30 November 2010

  39. Conclusions • Commissioning of the 4 quarters had been extensively done on the H8 beam in the past months. • Both hardware and software checked and functional. • Transport of 2 quarters to IP5 planned for the beginning of December (7-10) • The other two quarters will preferably be transported beginning of January (7-8) We are ready for installation Thank you for your attention.
