MSU Optical Installation Monitor
Maintained by: RJM
Last Update: Jan.15, 2001
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.
The following table gives some detail for each module instrumented at MSU. The Check Sheet and Test Results columns contain links to those documents. Test result ntuples contain one row for each tile with the following columns:
CELL LAYR TILE SLOT ADCOL ADCEL ADCOC ADCEC ADCOR ADCER,
where CELL = nxx with n = 0:3 for readout depths A:D, and xx = the eta index of the cell; and LAYR = 0 (1:11) for samples normalized to 100 over all tiles on this PMT (within a tile layer); TILE is the tile number within the CELL, starting from the ITC end; SLOT is the fiber slot number, cummulative over cells, also starting from the ITC end with the first number offset so that all layers end with slot number 157 at the flat (non ITC) end; ADCO(E)L(C) is the ADC value for that cell for the odd (even) side PMT, normalized to give an average of 100 for tiles in this PMT-layer (PMT-cell), and ADCO(E)R is the unnormalized peak height.
Details of the modules instrumented at ANL can be found here.
