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 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

4

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

DD



5


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

DD



6


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

DD



7


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 stuffingInstall 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 weeksAug-00 ** Receive and certify 10% BLS boards

Install CC cooling, power and preamps; checkout with final prototype BLS

CC SW started already (1 crate)(physicist shifts)

Cleanup ECN BLS (power + backplanes)Install ECS preamp cooling and powerCommission pulser control interface + calib.Start final T&C / fanout production

Sep-00 Install ECS fanouts, pulser cables, preamps

Start commissioning with prototype BLS (physicist shifts)Test prototype Trigger Pickoff/Summer cardsICD backplanes and cables installFill a cryostat and test seals and HV

Oct-00 Install ICD electronics and commissionNov-00 ** Receive and test final BLS

mother/daughterboards

(physicist shifts - SUNYSB)
