keyword=Changes to HV on neutron detectorThe high voltages on the neutron detector channels with the changed bases were changed as follows;
N1-5R: -1490 -> -1470 V N1-5L: -1540 -> -1500 V N3-12L: -1530 -> -1480 V
The voltages were decreased slightly because in looking at the adc
spectra for these channels for a cosmic ray test run, they are somewhat
larger than other channels which use KSU bases. This is illustrated in
the attached plot. The histograms on the left are those which had their
bases changed while those on the right are from other channels for
comparison.
