Details of 'manual' gain adjustment
tower | gain change | remarks |
---|---|---|
05TC12 | 1. or 2. | only pedestal seen or very low gain |
05TD04 | 1. | just pedestal is seen, dead ? |
05TD06 | 2. | low gain tube |
05TD10 | 2. | very low gain tube |
05TE03 | 1. or 2. | only pedestal seen or very low gain |
06TA12 | 1. | just pedestal is seen, dead ? |
06TB04 | 1. | dead tube |
07TD04 | 1. or 2. | just pedestal is seen, dead ? |
07TD05 | 0.74 | tube is probably fine !, but noise in 07TD04 kill most of entries |
07TD06 | 0.66 | tube is probably fine !, but noise in 07TE06 kill most of entries. Renne said this tube is dead ? |
07TD08 | 1.15 | tube is probably fine !, but noise in 07TE06 kill most of entries |
07TE06 | 1. | just pedestal is seen, dead ? |
07TE07 | 0.84 | tube is probably fine !, but noise in 07TE06 kill most of entries |
08TA05 | 0.75 | tube is probably fine !, but noise in 07TE06 kill most of entries |
08TA06 | 1.13 | tube is probably fine !, but noise in 07TE06 kill most of entries |
08TA07 | 1.63 | tube is probably fine !, but noise in 07TE06 kill most of entries |
08TB02 | 1. or 2. | dead tube |
08TB07 | 1. | bit0 set to 1? is it possible |
08TD04 | 1. or 2. | dead ? |
supporting material for M-C dAu events
60K M-C minB dAu events. Towers are gain match for E_T max=60 GeV.
Y-axis shows slope of the isolated MIP spectra.
X-axis numbers 240 towers in sectors 5-8.
The physical eta=2.0 is on the left end, eta=1.06 is on the right one.
The phi-bins advance with the step of 1 (1=05TA01 , 2=05TB01, ..., 20=08TE01), subsequent eta bins[1-12] increment X-axis by 20 (21=05TA02, 41=05TA03, ..., 221=05TA12).
Colors denote 3 crates.
Horizontal lines is the average over the whole eta bin.
+/- 1 sigma of the average are marked by dashed lines.
