2. The Xmas Run Xmas run started on the 23rd Dec. till Mon. the 9th
Connected: Module #4, #5, #6
Monitoring side (only for Module #5):
3 LED driven with prototype LED driver, steered by DAQ
+ 3 PIN diodes r/o on prototype preamp. boards (Ivo)
In addition 16 ECAL slabs were connected and “partially” in operation trigger distribution problems + high leakage current
Cosmic trigger: coincidence of 2 30x40 cm2 scint. plates ~1m apart

6. Run report Electronics: VFE: working fine  No unexpected DAC losses
CRC: warning! Too many FE with problems
 1 prototype CRC back to Paul for debug
 we have: 2 ECAL prototypes and 1 HCAL serial production
Slow control:
Working fine!
HV stable
~ 2 C day/night temperature fluctuation + T-jump when opening the tent door

8. Data taking First run on dCache: Dec 25 16:46 Run110931.bin
The data taking loop:
2.1 Gby (300k ev) in ~15h: cosmics LED ped
0.4 Gby (80k ev) in ~20 min: 17 steps saturation curve calib. mode steps gain calib.
0.3 Gby (50k ev) in ~15 min: 42 steps saturation curve phys. Mode
Week 1) due to a “bug” in the DAQ ~350 runs collected, mainly calibration
Week 2) bug fix ~40 runs collected with correct loop (~3Gby / day)
 ~ 3 Mev cosmics + plenty of calibration data
All runs copied to dCache and converted to LCIO
Event size: 4 byte/ev/chan (.bin)
2 byte/ev/chan (.slcio) + database

Long Discharge Update
At the closing of the modules / before connecting VFE electronics:
Mod 4: 5/0 , 2/15
Mod 5: 11/3
Mod 6: 11/0, 0/5
After connecting VFE electronics (and during 2 weeks of operation):
Mod 6: 11/0, 0/  new: 3/13
After Xmas run (2 weeks of operation):
Mod 5: 11/  new: 3/10, 11/8 (?)
Mod 6: 11/0, 3/13, 0/5  new: 1/10

Outlook
Plenty of data to be analyzed
Software for analysis and calibration is under development
Last week changed to new / ”final” DAQ version for test beam
Large part of code & online display has to be rewritten
April combined test DESY with ECAL + few HCAL modules
Upgrade the cosmic setup to host more modules
Simulation of prototype in the new MOKKA framework and with correct geometry is still missing
