Test Results

The following table shown a list of the ~30 out of  476 small cells that need more attention:

The 11 cells shown in yellow were calibrated and used in run 9 but have either not yet been fully tested or have been tested and found to work with some problems.

The 5 cells shown in blue are fine but the recorded mapping indicating which channel (id1,id2,id3,id4) is connected to which detector (nstb1,chan1) was incorrect. 

The 15 cells shown in red are not functional. The first 9 of these appear to have good HV but little or no output signal. The last 6 appear to have high voltage problems with their bases.
