R5900 16-Channel PMTs

We have chosen to use Hamamatsu R5900 16-Channel photomultiplier tubes based on their excellent performance characteristics. In excess of five-hundred tubes will have to be tested before being shipped to the CDF experiment at Fermilab, and we have a number of requirements that each tube must meet. The original specifications can be read in this document and were modified in this document.
