## Calorimeter Electronics Status

## Calorimeter Commissioning Shifts

**Shifts ongoing 2-3/day**
**U. Bassler,                       M. Bhattacharjee,            V. Bhatnagar, L. Duflot,  T. Eltzroth, S. Fu, M. Gao, R. Hauser, M. Hohlfeld,  B. Kehoe, N. Parua,        M. Ridel, D. Schamberger, M. Tuts, V. Zutshi**
**Concentrated on CC**
**Working on software (examines, GUIs etc.) for online debugging and commissioning**

## Calorimeter Preamps and BLS

**Preamp**
**All 1152 m/boards with 48 preamps per board tested and installed (55k) **
**3 secondary PS to install (21/24 + 1 ICD installed)**
**Cooling fan needs rework in one box  (~4-8 hr)**
**All calibration pulsers installed, cabled, tested and commissioned**
**Commission preamps and readout chain**
**Fix known broken cables**

**BaseLine Subtractor (BLS)**
**29/36 PS installed (1 to repair), 6 ready to be installed, (need  ~8 hr to install + test)**
**9/12 quadrants populated (864/1152). Need ~300 more**
**Final board assembly and testing at SUNY-SB (about 50/week).  Awaiting about 150 boards from manufacturer.**
**Commission**

## Calorimeter ADC, T&C + Trigger

**ADC & T+C**
**Run I ADC’s working fine**
**ADC controllers modified and being tested**
**3 prototype Timing and Control cards being used**
**10 more being stuffed at SUNY-SB  (~1-2 next week)**
**Still need T+C Crate controller (1-2 week layout, 2 week production)**
**More than 3 (8) crate readout into L3 a concern due to lack of VRC slots**
**PIB control prototype working.  Final board production soon and communication with T&C controller needs to be tested**

**L1/L2 Trigger**
**Trigger drivers (2 EM + 2 HAD per board)– have all CC (1.5k).  EC in 2 weeks.**
**Trigger summers (4 EM + 4 HAD per board) – only assembling CC at moment (3k).  Few boards worth next week, final delivery in ~2 weeks.  Need testing at FNAL,  installation.**
**Can test and time in L1 trigger with a few towers**
**Noise issues on readout are a concern**
**Simulations ongoing for layer-weights to get final EC trigger resistor values (incl. MG + ICD regions)**
**Commission**

## Calorimeter LAr, HV and ICD

**ICD**
**5 tiles installed on ECS-SW**
**PMT box, HV + LV power, electronics pulser installed**
**Cables run through the winders**
**pORC in the works – need this before can turn on power**
**Calibration and characterization ongoing in cosmic ray test-stand**
**Final install in April – will move PMT box few inches to avoid Silicon cables**

**LAr and HV**
**All cryostats filled with LAr – no leaks!!!**
**All HV has been turned on to 2kV on all channels**
**LAr purity tested      (< 0.4 ppm O****2**** equiv.)**
**HV cables reinstalled and tested**
**LAr temp. and purity being monitored**

## CalorimeterCalibration, Downloads + Controls

**Calibration**
**Pedestal calibration data sent to and processed in L3 scriptrunner node**
**Data sent to CalibManager and then to Oracle dB**
**Python tools extract data to ***pickle*** files**
**Working on handling gain runs with pulser**
**Automatic validation and extraction tools needed**

**Downloads/controls**
**Final download system (COMICS) not in place yet but tested with prototype**
**Pedestal and limits files read from pickle file in Comics and downloaded to ADC**
**Working on pulser  and T&C communication**
**Control GUIs (via EPICS) for LV and HV work**
**General alarm monitoring of all systems and control GUIs need to be implemented and made more robust**

## DØ Calorimeter Status at Begin of Run II

**Summary**
**Start with ~4 crate readout (CC) + T&C crate**
**Debugging + commissioning (CC then EC’s)**
**Almost all infrastructure in place**
**9/12 quad’s instrumented**
**5/16 ICD tiles on ECS**
**12/12 quad’s by end of 6 weeks assuming some access**
**Some trigger summers/drivers installed by end of 6 weeks (all of CC?)**
**Timed in to L1 trigger**
