Preliminary EEMC Timing Curves by Crate + Individual Channels

Introduction

 

The following runs were taken for EEMC timing:

 

Run       ETOW TCD   ESMD TCD   # of events processed (to nearest 100)

10065031 80 80       42100   
10065032 10 10       56900
10065033 20 20       84000
10065034 30 30       79400
10065035 40 40       72000
10065036 50 50       70100
10065037 60 60       71800
10065038 70 70       71400
10065039 75 75       72600
10065040 65 65       72400
10065041 55 55       79400
10065042 45 45       92900
10065043 35 35       81100
10065044 25 25       87000
10065045 15 15       89400
10065046 5 5           64400

 Note: additional runs were taken close to nominal, I have not include those yet.

The results here are with all the files available after the "missing" files were restored from HPSS.  We are still missing some stats because of the problem of only the first MuDsts per daq file being copied for daq files with a large number of events.  I added a column above that has the number of events in the MuDsts.

 

Method

 

I examine the dependence of sum of ADC-ped=20 to ADC-ped=100 versus the time delay.  Only when summing channels into crates, I exclude channels that have pedestals that are 4 sigma above or below the average for that crate.  This does not affect the individual channels, which are all given as attachments.

Results

 

2007 results are here.
