Checking Tower mapping with led - setup for 2005 Run (as of October 26, 2004)

Each file contains a 12-eta by 12-time slot plot of histograms for a given sector and subsector. On the horizontal axis of the 12 by 12 plot is eta, 1-12 consecutively from left to right. On the vertical axis is time slot, from 1-12 consecutively from top to bottom. Each element in the plot is an individual histogram corresponding to a particular eta and time slot. For each element histogram both the x and y axes are shown with the log scale for easier viewing. One should see a diagonal pattern if the correct eta corresponds with the correct time slot.

Jan's Comments:
The HV test was fully automated.
First DAC value in all 240 cells was set to zero, tower by tower (you
know I do not trust global commands).
Next, for 60 consecutive towers A01, A02, ...A12, B01,.... E12 the HV
was switched on for ~7 seconds, one at a time.
Simultaneously in 4 sub sectors, depending which HVsys controller was
used. The unix time  just after any HV on command was recorded in the
log file. All events were stored in one ezTree-file.
                                                                                
Melanie uses this unix time to select only this 7 seconds of relevant
time. She is accumulating all 720 towers each time and save histos in
different file.
(It is overkill, but we used existing event sort as is.)
                                                                                
Melanie is displaying 12 towers for 12 consecutive time slots. For eta
bins 2-11 we see also data from previous and later time slots. Even if
she would missed a time slot by one the peak(s) would show up in
off-diagonal plots. I do not see this.

all fine = see signal for each eta and matches the correct time slot

High Voltage and LED setup information.

Select tower led response - using 345K events. The top plot show the frequency that a given tower had an energy above a threshold of 0.5 GeV (this is denoted by the black curve). Also for the top plot, the frequency of events for which the tower in question had an energy less than 0.5 GeV (this is denoted by the red dashed curve). The bottom plot shows the ratio of the red and black curves. There are four towers examined:

The x-axis covers three phi bins 09TE,10TA,and 10TB, where 1=09TE01, 13=10TA01, 25=10TB01...

The x-axis covers three phi bins 11TE,12TA,and 12TB, where 1=11TE01, 13=12TA01, 25=12TB01...

The plots show that for each of the four towers above, the frequency of events decreases for surrounding towers for the case that the given tower had an energy below the threshold while all other towers had an energy above the threshold.Conclusion: the database was right for last year.
