1 DØ Algorithms Meeting April 6, 2001 1 Leslie Groer, Columbia Univ Ursula Bassler, LPNHE, ParisCalorimeter Online Software Status 1  Examines  Crate Unpacking  Calibration  Layer-Weight calculations  Downloads, Control & Monitoring  Displays

2 DØ Algorithms Meeting April 6, 2001 2 Leslie Groer, Columbia Univ Ursula Bassler, LPNHE, ParisCalorimeter Online Software Status 2 Calorimeter Examines – Cal_elec  Cal_elec – Mrinmoy Bhattacharjee  electronics co’ords:   ADC counts  vs channel   vs channel  online version for calorimeter commissioning and monitoring  default version for shifters to be run once per day:  takes 200 events per crate  check readout status for all calorimeter crates using pedestals and pulsers  reference histograms being provided

3 DØ Algorithms Meeting April 6, 2001 3 Leslie Groer, Columbia Univ Ursula Bassler, LPNHE, ParisCalorimeter Online Software Status 3 em-channel had-channel Delay = 50 Calorimeter Examines – Cal_elec  Cal_elec  offline use via SAM as basis for refined analysis  newly implemented:  mapping of pulser channel vs readout channel  histograms under development  unpacking of T&C information  unpacking of PIB information  Bob Kehoe developing separate branch for L1 Cal trigger debugging and commissioning “delay ramp” “dac ramp”

4 DØ Algorithms Meeting April 6, 2001 4 Leslie Groer, Columbia Univ Ursula Bassler, LPNHE, ParisCalorimeter Online Software Status 4 Calorimeter Examines – Cal_examine  Cal_examine – Florencia Cannelli  Physical co’ords – also meant for ICD, CPS & FPS  Been run during workshops but not much else yet  Some success at running with xgooey/ROOT with help of Joel Snow  Runs also with histoscope, raw data, MC, network and file modes and ssh  Needs trigger tower views eventually  Built at t01.35.00 offline, but t01.24.00 for online (xgooey broken in t01.31.00)

5 DØ Algorithms Meeting April 6, 2001 5 Leslie Groer, Columbia Univ Ursula Bassler, LPNHE, ParisCalorimeter Online Software Status 5 Calorimeter Crate Unpacking  To be added to ADC unpacking:  Simultaneous read out of gain1/gain8  Unpacking of 3 consecutive crossings for timing calibration  Timing & Control - Crate (0x4C)  Contains all meta-data (L1 crossing, analog-cell read out, PIB information etc.)  Existing unpacking from cal_elec to be generalized  L1CAL - Crate (0x10)  Structure similar to Run I but there are significant changes in particular for L3 readout  Bob Kehoe looking into this as he works on L1Cal Analysis tools (thanks to Phillipe Laurens for details)

6 DØ Algorithms Meeting April 6, 2001 6 Leslie Groer, Columbia Univ Ursula Bassler, LPNHE, ParisCalorimeter Online Software Status 6 Calorimeter Electronics Calibration  Online Calibration – Taka Yasuda  Pedestal calibration data sent to L3 scriptrunner node (L3CalCalib – Mrinmoy Bhattacharjee + Jonathon Hays)  Data sent to CalibManager which stores data in Oracle dB  Python tools extract data to pickle files  Automatic validation and extraction tools needed for pedestals and zero suppression limits  Mrinmoy working on handling gain runs and ramps with pulser  Scheme for running calibrations still needs to be worked out (frequency, #events, #DAC/delay settings, etc.)  Offline Calibration – Ursula Bassler  data base tables designed – might want to retrofit online  Estimate 25 GB for 3 years for offline database  development of online/offline transfer and DB-Manager code

7 DØ Algorithms Meeting April 6, 2001 7 Leslie Groer, Columbia Univ Ursula Bassler, LPNHE, ParisCalorimeter Online Software Status 7 Calorimeter Layer-weights  From Vishnu Zutshi  EM section  Optimized layer weights for the 4 EM layers have been calculated for the whole calorimeter using electrons in plate geometry.  Weights calculated as a function of the tower ieta.  HAD section  Weights for the hadronic sections are being calculated using single pions.  Weights for the EM layers are kept fixed relative to their electron values.  Coarse hadronic sections are being appropriately left out from the optimizations.  Distinct from Run I there exists a possibility of having massless gaps and ICD at L2. Weight calculations for these are being looked into.  Weights for CC done and resistors ordered. Next need EC’s and then ICR.

8 DØ Algorithms Meeting April 6, 2001 8 Leslie Groer, Columbia Univ Ursula Bassler, LPNHE, ParisCalorimeter Online Software Status 8 Calorimeter Downloads, Controls & Monitoring  Downloads/Controls  Bill Lee and Fritz Bartlett working on COMICS  COOR communication  Pedestal and limits files read from pickle file in Comics and downloaded to ADC  Pulser control GUI working fine:  implementing broadcast function to all pulsers  working on COOR integration  General alarm monitoring of all systems needs to be implemented, turned on  More robust GUIs

9 DØ Algorithms Meeting April 6, 2001 9 Leslie Groer, Columbia Univ Ursula Bassler, LPNHE, ParisCalorimeter Online Software Status 9 Calorimeter Event Display  Have 3-D display with cell information and Lego plot already  Nobu Oshima working on integrated 2-D display  Toby Burnett working on the Calorimeter display  Hope to have simple r-  and r-z E and E T views soon  Also might work on Cal Trigger Tower Lego plot  Orsay group has simple implementation of 2-D view
