05 Absolute Calibration from Electrons

Under:

We use the MIP ADC location calculated in part 03 to get a preliminary measure of the energy scale for each tower.

The following formula from SN436 provides the calibration coefficient:

03 MIP peak analysis (TPC tracks, 2008 pp data)

Under:

I examined runs from 2008 pp (list attached below) to create calibration trees (using StRoot/StEmcPool/StEmcOfflineCalibrationMaker).

Proposal

We propose to add a new set of tables to the Calibrations_emc database that will track the electronics mapping for the BEMC, BSMD, and BPRS and allow for an alterna

16) Time stability by fill of BSMD pedestals

Under:

I calculated the pedestals for every PP fill for 2008. This plot shows the pedestal per stripID and fill index. The Z-axis is the value of the pedestal.

Collected here is information about BSMD Calibrations.

2006 Gain uniformity

Under:

Using the gains we calculated for 2006 tower by tower from the MIPs and then corrected with the electron eta rings, I calculated how it differed from the ideal gain assuming containment of an EM sh
