June 21-28 data taking (delivered 77.7 /pb, recorded 72.0 /pb)
June 29-July 03 MD
July 04-08 technical stop
July 09-13 re-commissioning with beam, recovery from power cut 10/07
July 14 resumed data taking
3Yu. Guz
Smooth data taking. Very few things to be mentioned:
1). Daniel have introduced a new SPD temperature panel, to be used in the checklist.
2). 21/06 the calibration farm analysis did not provide any plot into the presenter. Solved by rebooting the hist01 machine (Beat).
3). 27/06 the L0hadron errors in the emulator comparison appeared (more details in next slides)

Before the technical stop

1). 05/07/11 morning: ECAL CW studies: MV currents and pumping frequency measurements 05/07/2011. A noticeable decrease of the pumping frequency had been observed in PM/CWs closest to the beam. Details in Irina’s presentation today;
2). 05/07/11 12:00: HCAL emulator comparison problem since 27-June. For cr. 24 FEB11, solved by Marie-Noëlle and Cyril D. 05/07/2011: the two cables coming from the FEB#11 crate 24 moved from input 0 to input 3 on both TVB5 and TVB7 side A;
3). 05/07/11 evening: HCAL 137Cs calibration 05/07/2011 (HV recipes updated next day 06/07/2011). Details in the HCAL presentation today;
4). Several attempts to perform the SPD threshold scan during the technical stop, without success (?).

Technical stop activities 4-8 July

1). LV/MV/HV system recovery after power cut: a reminder (the procedure is described in the Patrick’s presentation at the Calo piquet training 21-Oct-2009, http://indico.cern.ch/getFile.py/access?contribId=2&resId=0&materialId=slides&confId=70825)
‒ check that the Agilents in D3 are powered and have output voltage OFF
‒ make sure that all the equipment in our rack (B1B01) at the D1 balcony is powered: turbine of this rack, rectifiers, RCM crates, Ethernet switch (at the very bottom of the rack);
‒ in case if 220 V AC power is absent on something of the above – call Laurent 162989 (or DSS expert) to switch it back ON at TDM drawers
‒ if the RCM crates are OFF –switch them ON manually
‒ after that, check the system. DO NOT TRUST “GREEN” FSM STATE!!! Try to switching some item ON/OFF via FSM; if it fails, restart the MARATON OPC server(s):
• CADCSLV: via service+ on cadcs01w
• INFDAI1: ask Beat to do it.
‒ then proceed with MV and HV

2). Problem at configuring TVBs: solved by Marie-Noëlle by restarting SpecsServer at ECDAQHVC1W and ECDAQHVA01W.
3). the PRSHVC1 project got corrupt. Recovered from backup by Daniel.
‒ the backup was of 01 February: had to manually add the changes introduced in April, namely reconnection of C1004B19D02 from Bd#5 to Bd#6, new HV recipe and slight modification of lbPRSHvMon.ctl script. Project backups probably have to be done more frequently (every technical stop?).
4). Problem with LEDTSB @ HCAL side C: in 23 out of 26 outputs used in HCAL C, the timing shifted 1 BX earlier (T0Prev1). Not understood: simply introduced new settings corrected for that, and saved them as a DEFAULT recipe,
‒ then encountered a subsequent problem: at CONFIGURE, old settings were being loaded into the module, although it was verified that the DEFAULT recipe itself contained new ones
• solved by Luis by restarting the FSM’s PVSS00ctrl

L0hadron operation
Crate24 FEB14 run 96291 18/07/2011
re-appeared, still pending
Crate23 FEB07run 95946 14/07/2011
14/07/11: replacement of FEB07 and TVB was unsuccessful
fixed next day by re-plugging the TVB cable into another output of FEB07
Crate24 FEB06, FEB11, FEB14since run 94341 27/06/2011
FEB11 errors fixed during TS by rearranging cables in TVB5 and TVB7 (side A)
FEB06 & FEB14 errors gone by themselves
The operation becomes unstable, we should keep an eye on it.
