10 -------- BPRS swaps take2, _AFTER_ applying Rory's swaps

2nd Correction of BPRS mapping (after Rory's corrections are applied).

INPUT: ~7 days of fmsslow-triggered events, days 64-70, 120 runs
DATA CORRECTIONS:
- private BPRS peds(cap,softID) for every run,
- private status table, excluded only 7 strips with ADC=0
- event-by-event capID corruption detection and correction
- use vertex with min{|Z|}, ignore PPV ranking, to compensate for PPV problem
- BPRS swaps detected by Rory in 2007 data have been applied
TRACKING:
- select prim tracks with pr>0.4 GeV, dEdX in [1.5,3.7] keV, |eta|<1.2, zVertex <50 cm
- require track enters tower 1cm from the edge and exist the same tower at any distance to the edge (0 cm)
- tower ADC is NOT used (yet)
3 2D histograms of were accumulated:
- rawADC-ped (softID) for all events
- the same but only for BPRS tiles pointed by QAed MIP TPC track
- frequency of correlation BPRS tiles with MIP-like ADC=[7,30] with towers pointed by TPC MIP track

Based on correlation plot (shown as attachment 6) I found ~230 miss-mapped BPRS tiles (after Rory's correction were applied).

Once additional swaps were added ( listed in table 1, and in more logical for in attachment 3) the correlation plot is almost diagonal, shown in attachment 1.

Few examples of discovered swaps are in fig1. The most important are 2 series of 80 strips, each shifted by 1 software ID.

Fig 2 shows MIP signal shows up after shit by 1 softID is implemented.

The ADC spectra for all 4800 strips are shown in attachment 2. Attachment 5 & 6 list basic QA of 4800 BRS tiles for 2 cases: only Rory's swaps and Rory+Jan swaps.

Fig 1. Examples of swaps, dotted line marks the diagonal. Vertical axis shows towers pointed by TPC MIP track. X-axis shows BPRS soft ID if given ADC was in the range [7,30] - the expected MIP response. Every BPRS tile was examined for every track, multiple times per event if more than 1 MIP track was found.

Left: 4 sets of 4 strips needs to be rotated. Right: shift by 1 of 80 strips overlaps with rotation of 6 strips.

Fig 2. Example of recovered 80 tiles for softID~2850-2900. Fix: softID was shifted by 1.

For the reference:

mapping of BPRS softID to MAPMT made by Will J. in 2007 is shown here: http://www.star.bnl.gov/protected/emc/wwjacobs/tmp/bprs_tubehookup_run7.pdf

Below I listed BPRS tiles which look suspicious. However it is not a detailed study, there is more problems in the histos I have accumulated.

BPRS status tables need more work, in particular channels with close to 100% cross talk can't be found using single spectra, because they will fine (just belong to another channel)

Identified BPRS hardware problems:

Tiles w/ ADC=0 for all events:

* 3301-4, 3322-4 - all belong to PMB44-pmt1, dead Fee in 2007
   belonging to the same pmt:
     3321 has pedestal only
     3305-8 and 33205-8  have nice MIP peaks, work well

* 2821, 3781 , both at the end of 80-chanel shift in mapping
     neighbours of 2821: 2822,... have nice MIP 
     similar for neighbours of 3781

* 4525, 4526 FOUND! should be readout from cr=2 position 487 & 507, respectively 
 
I suspect all those case we are reading wrong 'positon' from the DAQ file



Pair of consecutive tiles with close 100% cross talk, see Fig 4.
35+6, 555+6, 655+6, 759+60, 1131+2, 1375+6, 1557+8,
2063+4, 2163+4, 2749+50, 3657+8,   
3739 & 3740 copy value of 3738 - similar case but with 3 channels.
4174+5


Hot pixels, fire at random
1514, 1533, 1557,
block: 3621-32, 3635,3641-52 have broken fee, possible mapping problem 
block: 3941-3976 have broken fee


Almost copy-cat total 21 strips in sections of 12+8+1
3021..32, 3041..48, 3052
All have very bread pedestal. 3052 may show MIP peak if its gain is low.
