TPC hits by padrow
(This entry is meant as additional input in a thread on Run 9 TPC studies/QA.)
Using the Offline QA TPC Sector histograms combined from 20 files of runs 10129049 and 10129050, I see the following distributions for each of the 24 sectors (PDF versions of these plots are available as attached files at the bottom of this page).
Notes:
- Sectors 13 & 20 show no qualitative differences from other sectors (which don't have any dead RDOs/FEEs/Anodes).
- Padrow 8 always see an excess of hits. This padrow is the only one which is covered by two RDOs, but I don't see why that matters.
To help in understanding the layout of RDOs and anode channels, I include here a 2D plot of the hits from Sector 1 (padrow vs. position along the padrow in [cm], not pad numbers) with lines to indicate boundaries of RDOs and anode channels. A PDF with all 24 sectors is attached at the bottom of this page. These plots make the following obvious:
