04 Spectra from Problem PMT Channels
Updated on Sat, 2009-03-14 22:55. Originally created by trent on 2009-03-14 22:55.
Under:
We set the HV = 800 Volts for all channels which have been masked out, repaired, or otherwise had problems in 2008. I have examined the spectra for these channels and give pdfs with each of these spectra:

I identify 37 tubes which are dead, 39 tubes which can be adjusted, and 1 with a bit problem. We should pay careful attention to these tubes in the next iteration.
