Hello guys, I have 2 of R7600-03-M64 MaPMT from Hamamatsu. and I want to test is.
First at all I want to measure the dark current, so I make a black box and I put the PMT inside and with an osciloscoppe with 50Mohm termination I connect 3 random pixels (8, 31, 62). I power up the MaPMT with PS325/2500V-25W from Stanford research. The voltage applied is -600 to -900 in step by seconds. Now I don't get anything on the scope. only some noise. Somebody can provide me some steps to measure dark current, in case mine is wrong?
Regards.
