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

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

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

Saverio MINUTOLI Requests (2) TOTEM T1 Readiness Review, 30 November  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.

Saverio MINUTOLI Requests (2) “Panels and Cables” TOTEM T1 Readiness Review, 30 November 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

Saverio MINUTOLI Requests (2) “Remote monitoring” TOTEM T1 Readiness Review, 30 November 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.

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

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

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

Saverio MINUTOLI Requests (3) TOTEM T1 Readiness Review, 30 November  Verify with the manufacturer that the flat cable crimp quality is qualified for power distribution of the foreseen levels. The CSORVEM company ( ISO9001) has confirmed that all its products are tested both mechanically and electrically within the limits of the characteristics of the components. 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 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 2 ) for the flat cable. The manufacturer confirms that the crimp quality is qualified for power distribution of the foreseen levels.

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

Saverio MINUTOLI Requests (4) TOTEM T1 Readiness Review, 30 November  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
