9 A history of 3 chambers 2/10/2015I. Redondo YB2 S12 MB4 MiniCrate ⁻  Splitter box exchange solved the issue.  took a long time to diagnose ⁻ YB-2 S3 MB3 MiniCrate  first theta TRB exchanged YB2 S3 MB2  CCB unresponsive after a few seconds, voltages readback ok during the first seconds. ⁻ Franco+Daniele exchanged CCB+SB Wendesday night YB1 S11 MB3, did not communicate at all ⁻ early access got on Thursday, used Friday and Saturday to exchange CCB+SB The 3 failures were identified just after powering up the system from a power cut

10 MiniCrates: “New?” failures Post Mortem 2/10/2015I. Redondo Faulty boards went to Padova after gamma spectroscopy, being investigated by Lorenzo Castellani 1.Splitter box? Franco: Faulty Opamp ⁻ MAX4167 (splitter IC2) abnormal 10uA current from pin2 to gnd 2.PRELIMINARY “yb+1 S11 MB3 the problem is on CPLD (Altera MAX7000), it contains a CK mux for CPU” ⁻ It was not possible to reprogram 3.DEFINITIVE diagnosis for SB/CCB yb+2 S3 MB2: ⁻ 30 broken welds (with little tin) on J44, probably due to mechanical stress during installation or thermal expansion (but this is unlikely since there is no power in the connector).  Eitherway, we should use power_slow pythons as long as it is possible Are these “new” failures? Fabio had a critical view at the failures talking to other experts and looking at past experience. Results: ⁻ No other J44 break ⁻ 1 only CPLD broken time ago ⁻ No splitter-OPAMP IC broken before. “In brief, I think that both 3 failures are further signals of aging but [being different failures and not an epidemy] still we have no elements to really worry about. Anyway we have to maintain a high level of attention. We know that the system will behave worst with time.”

14 Action Matrix Review 2/10/2015I. Redondo Dear All, The end of LS1 is in sight and CMS has to be ready for beam operation soon. An important condition is to be certain that faults and failures of detector parts or of the infrastructure at PT5 will be handled. correctly by automatic procedures or human intervention. Therefore we plan a series of reviews of the DCS & DSS action matrices of all subdetectors. There will be a standing review committee invited to all reviews. As we will have 8 reviews, I have chosen a rather large committee in the hope not sitting alone with the subdetector representatives after the first few meetings... The committee consists of: Christoph Schäfer, Niels Dupont, Laetitia Bardo, Alain Meynet, Silverio Dos Santos, Hourari Sabba, Sergei Lusin, Nicola Bacchetta, Austin Ball and W.Z. From the reviewed component we expect at least the field coordinator and the safety representative being present. The components we will review are CSC, RPC, DT, ECAL, HCAL, Tracker, Magnet/Cryo and general infrastructure The dates for the reviews will Wednesday morning 9:30 at PT5 in the upstairs conference room of the new building SL53. All subdetectors will receive separate invitations with a more detailed description of what we expect, starting with the Tracker this coming Wednesday Febr. 4. Best regards Wolfram  Wednesday February 18 th is suggested date

18 1-Up to LS2 (including) : No activation expected. 1.1 UXC. Chamber and Minicrate maintenance. 1.2 UXC. Possible extension of the MB4 shield (to be decided with LS1 installed prototype) 1.3 UXC. Installation of Minicrate prototypes for the LS3 upgrade. * There could be limited machining involved in the attachment of the new MC mechanics. 1.4 USC. Electronics upgrades 1.3 USC. CAEN Mainframe replacement 2/10/2015I. Redondo * This is the major source of material exposed to radiation (not activated) that we may want extract from UXC. The Minicrate material is basically an Aluminum cage but electronics inside have small quantities from heavier materials. One of the options we are studying to minimize the intervention time for logistic reasons, not for ALARA, leaves the MC in place, only extracting cables from UXC: -FE flat cables ~ 1.5 m x 30 x 250 -Signal cables ~ 50 m x 4 x 250 We are working under the assumption no activation is expected in LS3 between the wheels, at the location of the MiniCrates, but indeed activation maps for LS3 in between the wheels are needed to confirm this assumption. In fact, one possibility under consideration by the upgrade management is staging the replacement to LS4. Activation maps for LS3 and LS4 would be very much welcomed. - The radioactive waste to be disposed  None expected - The storage of radioactive material to be foreseen  None expected - The machining on radioactive material to be performed  None expected At the current stage the DT upgrade plan has scheduled the following activities up to 2035: 2- LS3: Replacement of the MiniCrate system. 2.1 UXC.DTchambers. Replacement of 250 mincrates itself.* 2.2 UXC.Balconies Adapting LV Power Supply system 2.3 UXC.Balconies. Possible replacement HV Power supply system. 2.2 USC. electronics upgrades
