22 Saverio MINUTOLI Alignment laser beams system TOTEM T1 Readiness Review, 30 November 201022  Alignment system of CMS traversing T1: Checked all cables for possible interference Mechanical fixation to keep cables from entering laser beam zone

23 Saverio MINUTOLI Grounding and Shielding systems TOTEM T1 Readiness Review, 30 November 201023 Shielding of the digital signal cables completed Reinforced electrical connection of Aluminum structure parts Earthing point on CMS finalized (Sergei and Dmitry) Main grounding ribbon running the length of the support frame

24 Saverio MINUTOLI 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 201024

25 Saverio MINUTOLI Requests (1) TOTEM T1 Readiness Review, 30 November 201025  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.

26 Saverio MINUTOLI Requests (1) TOTEM T1 Readiness Review, 30 November 201026 Cavern GROUNDMain grounding ribbon CSC ground reinforced Frame joints reinforced Boards support grounding

27 Saverio MINUTOLI Requests (2) TOTEM T1 Readiness Review, 30 November 201027  The committee endorses the insertion of fuses to protect 1.5mm 2 power cables between the LV power supply and the 6 th 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.

28 Saverio MINUTOLI Requests (2) “Panels and Cables” TOTEM T1 Readiness Review, 30 November 201028 Fuse Box Front view Fuse Box Rear view New LV cables New 6 th frame LV Distribution Box ¼ T1 internal LV and Vsense cabling

29 Saverio MINUTOLI Requests (2) “Remote monitoring” TOTEM T1 Readiness Review, 30 November 201029 Fuse ROC_TOP blown All ROC Fuses OK ROCs 2V5 Main power OFF DOHM Fuse OKDOHM 2V5 Main power OFFFuse DOHM blown  By means of an optoMOS, the information on the status of each of the fuses is stored in digital format, optically isolated from the DCS system. The three fuse status bits for each ROC plane, plus the ON/OFF status of the main voltage, are fed to an R-2R ladder network.

30 Saverio MINUTOLI Requests (2) “Vsense redundancy” TOTEM T1 Readiness Review, 30 November 201030 Vsense Box Added Low Voltage sense redundancy in order to avoid Slow Control Ring break due to the master ROC failure.

31 Saverio MINUTOLI Requests (2) “Vsense behavior in failure mode” TOTEM T1 Readiness Review, 30 November 201031 OVP = 4V OVP = 3.3V OVP = 2.9V

32 Saverio MINUTOLI Requests (2) “Vsense behavior in failure mode” TOTEM T1 Readiness Review, 30 November 201032 Can be forced to zero by SW  5ms.

33 Saverio MINUTOLI Requests (3) TOTEM T1 Readiness Review, 30 November 201033  Verify with the manufacturer that the flat cable crimp quality is qualified for power distribution of the foreseen levels. The CSORVEM company (www.csorvem.it ISO9001) has confirmed that all its products are tested both mechanically and electrically within the limits of the characteristics of the components.www.csorvem.it Automatic and semi-automatic crimping machines and more than 40 different tools/die sets available. In our case Dielectric strength contact to contact of 500V and Current rating of 1.2A@20˚C for the Erni SMC type B connector. In our case Voltage rating of 50V and Current rating of 300mA considering a section of wire 0.050mm 2 (6A@1mm 2 ) for the flat cable. The manufacturer confirms that the crimp quality is qualified for power distribution of the foreseen levels.

34 Saverio MINUTOLI Requests (3) TOTEM T1 Readiness Review, 30 November 201034 ISO 9001 Quality test

35 Saverio MINUTOLI Requests (4) TOTEM T1 Readiness Review, 30 November 201035  The Committee endorses the plan for shielding of the flat cables to the chambers. All digital flat cables were removed from the detector and shielded with copper tape (35μm) welded at its overlapped ends. The shield was protected by an insulation braid. The shield was connected to the metallic cover of the ROC (source) by means of wire soldered to the cable shield on one side and a terminal lug to the other. Shielded cables

36 Saverio MINUTOLI 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 201036

37 Saverio MINUTOLI Installation test and infrastructure TOTEM T1 Readiness Review, 30 November 201037  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-DataDAQ-Trigger

38 Saverio MINUTOLI Installation test and infrastructure TOTEM T1 Readiness Review, 30 November 201038  Schedule and assignment of manpower finalized Presence of key people from CMS and TOTEM for the installation is defined. Availability of manpower confirmed : CERN, INFN, and availability of FSU The work to be completed before installation is on schedule

39 Saverio MINUTOLI Conclusions TOTEM T1 Readiness Review, 30 November 201039  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.
