Does any one know which PMT is used in the Harshaw 24MBHAS16/5B-QX. It is a 6" NaI but the tube is tape wrapped and I don't want to remove to see the tube...
Hello again, In Joseph DiVerdi's coincidence circuit shown on the group home page under 'electronics,' positive pulses from the GM's are put through the ...
Hi Daniel! ... Yes. The inverters are just used for pulse shaping and as you correctly said, 2 are used to have a positive pulse again. ... Yes #2. Better use...
... Dan, As Hannes has already noted, it is, in principle, OK to omit one of the inverters to accommodate the interface your are using to your PMT. However,...
