TileCalorimeter

 
A summary of the scan results for all of the US EB modules can be seen in the Postscript file linked here.

These plots have been generated from a summary ntuple that contains one row for each layer for each PMT for each module.  The ntuple contains the following 11  columns:
MODL  SCAN  LAYR  CELL  PMT  SIDE  NTILE  SIGMA   SO-E  S0+E  NBAD,
where MODL is the module number;  SCAN = 1 (2 ) for LED (Cs);  LAYR = 0  (1:11) for samples normalized to 100 over all tiles on this PMT (within a tile layer);  CELL = nxx with n = 0:3 for readout depths A:D, and xx = the eta index of the cell; PMT = the PMT number;   SIDE = 1 (2) for Odd  (Even) PMT;  NTILE is the number of tiles in the sample;  SIGMA = the rms variation of the sample;  SO-E (SO+E) = the rms variation of the Odd - (+) Even sides of the tiles divided by sqrt(2);   NBAD = the number of tiles in the sample that are less than 70% of the average.

Details of the modules instrumented at ANL can be found in Dave Underwood's www page and in Larry Nodulman's page.

A comparison of the Cs and LED scan results for the modules that have been scanned with both sources can be found here
