Calorimeter Examines – Cal_elec

Cal_elec – Mrinmoy Bhattacharjee (modified l3CalCalib)

Electronics co’ords Being actively used and upgraded weekly…currently adding

in channel info for pulser patterns (based on CalInfo from Reiner Hauser)

Using histoscope – tested ROOT offline. Discovered bug in histoscope when looking for .flprdefaults file.

B. Kehoe developing separate branch for L1 Cal trigger debugging/commissioning

Eventually develop base package/classes for all examines to use – incorporate all the channel info and mappings

Slight “feature” of casting unsigned ints in optimized compile still to be resolved

Online version is t01.24.00

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)

Calorimeter Crate Unpacking

Timing & Control Crate (0x4C) Contains all meta-

data (L1 crossing, analog-cell read out, PIB information etc.)

Structure very similar to ADC crates but is dynamic at the moment

Tibor Kurca (Paris) might work on this – will need guidance

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)

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

Developing data base tables – might want to retrofit online tables

Estimate 25 GB for 3 years for offline database Linearity and ADCGeV conversion

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.

7

Calorimeter Downloads, Controls & Monitoring

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

8

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 Et views

soon Also might work on Cal Trigger Tower Lego plot
