## Calorimeter Status and Plans for Mar-Apr ‘01

**Summary**
**Start with ~3-4 crate readout (CC)**
**Debugging + commissioning**
**8/12 quad’s instrumented, 5/16 ICD tiles on ECS**
**12/12 by end of 6 weeks assuming some access**
**Some trigger summers/drivers installed by end of 6 weeks**
**Timed to L1 trigger**

## 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**
**Concentrating on CC**
**Working on software (examines, GUIs etc.) for online debugging and commissioning**

## Calorimeter Electronics Install

**Preamp**
**1 primary + 5 PS to install + 1 ICD**
**Cooling Fan needs rework in one box  (~1 day)**
**All 1152 m/boards with 48 preamps per board installed (55k)**
**All calibration pulsers installed and cabled**
**Commission**

**BLS**
**24/36 PS installed, 6 ready to be installed, 6 more in final assembly/testing**
**8/12 quadrants populated (768/1152). Need ~400 more**
**Board assembly and testing at SUNY-SB about 50-100/week**

## Calorimeter Electronics Install

**ADC & T+C**
**Run 1 ADC’s working fine**
**ADC controllers modified and being tested**
**4 prototype Timing and Control cards being used**
**10 more on order (1-2 weeks)**
**Still need T+C Crate controller (1-2 week layout, 2 week production)**

**L1/L2 Trigger**
**Trigger drivers at assembler (doing all 2.3k)**
**Trigger summer – parts go out next week for CC (3k).  Estimate 3 week production.  Need testing.  Installation in hall.**
**Will test and time in with a few prototype towers**
**Noise issues on readout are a concern**

## Calorimeter Electronics Install

**ICD**
**5 tiles installed on ECS-SW**
**PMT box, HV + LV power, electronics pulser installed**
**Readout tested next week**

**HV**
**CC and ECN filled in Dec and HV turned on to 2kV on all channels**
**All cryostats filling this week**
**HV cables reinstalled, tested and ready to turn on**

## Calorimeter Electronics Install

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

**Downloads/controls**
**Pedestal and limits files read from pickle file in Comics and downloaded to ADC**
**Working on pulser control**
**General alarm monitoring of all systems needs to be implemented and more robust GUIs**

## Calorimeter Comissioning

| Jul 00 | Assemble new BLS power supplies; ORC
Complete preamp board stuffing |  |
| --- | --- | --- |
|  | Install cooling, power, preamps in ECN
     Test with old BLS
     ECN – SE (now), NE, SW, NW | debug + commission
    (physicist shifts) |
| 10-Jul-00 | ECS moves onto platform and available |  |
|  |      ECS cleanup (power, cooling) | (physicist shifts) |
|  |      Recable ECS | (physicist shifts) |
| 24-Jul-00 | Lose access to detector/MCH for ~ 2 weeks |  |
| Aug-00 | ** Receive and certify 10% BLS boards  |  |
