Since Yesterday I own a Canberra series 30 MCA. But I've a little Problem. I connected my Bicron Na(I) Scintillation Detector with the MCA. The MCS and MCSR Mode works wonderful. But the PHA mode, doesn't work. I have no count, except of the counts in channel zero, which are marking the time. Also I have only 512 Channels, but in the Manual is written, the there are 1024 channels. Can you help me?
P.S. I'm sorry for my English, I'm a Student from Germany and my English isn't very well
But I hope it will be better soon
