This is one of the best ever PMT tubes i've ever came across. Even better than the hamamatsu tubes i sell! It is type B29/B10/B23. This tube measures 1 inch diameter and is 4 inches long counting pins. Everything about this tube is designed for low noise and high sensitivity. The tube has an 11 stage dynode string and voltage divider that is designed for speed and precision more than absolute sensitivity as it is setup. It will work really well with most MCA's and scalers as it is. Minimum voltage is 500, maximum is 1500V making this suitable for most instruments. If you want to sacrifice some speed and pulse height resolution for frank sensitivity, you can very easily replace the resistors with up to 10M ohm to use with almost any geiger counter for a little time soldering, or just ask me to do it for 10megs. See my other listings for various scintillation crystals suitable for this tube. This item is extremely rare and esoteric, I have lots of lasers and other unique stuff for sale this week.
