Thanks for all the help guys. I have enough info now to utilize any of these PMTs. The "/SQ" and "/SN1" suffixes apparently are custom connection versions of the basic parts. These have small circuit boards soldered to leads that are welded to the tube pins, to adapt for hookup with in-line squ

Ed, Dang. Close but no cigar. I tried to save some time by describing the links to Photonis docs in parts. I blew it with errors. The beginning link was not the same for both datasheets and product guides. Then capitalization matters. Sometimes pdf, sometimes PDF. The gist of what I was expl

You might want to join this Yahoo group where the question would be more on-topic... http://tech.groups.yahoo.com/group/GeigerCounterEnthusiasts The Photonis site is one of those flashy-looking places where you can only find useful information if someone has already told you where it is. No fu

First off, try contacting the company. They are certainly still in the PMT business. Try www.photonis.com or Google: photonis -ebay It might be a selected version of a standard PMT. Their product line looks kinda like Burle, BTW. Definitely not Hammamatsu. -John > I just picke

I just picked up a bunch of nice apparently "new" condition Photonis brand PMTs, models XP3312/SQ, XP3212/SQ, XP5312/SN1, and XP5212/SN1. I found their website but it appears they don't make PMTs anymore, and have no info on their own former products. Searching around for the XP3312 so far, I
