I have a problem. I am working on send an electron beam onto the molybdenum z=42, but the events are very few. I use the molybdenum with a thickness of 50 micro and the window beryllium z=4 is 0. 5 mm. The filter is molybdenum z=42 with a thickness of 30 micro. at energy =50 keV
I have an inquiry about how much the distance between the anode and the electron beam is estimated ??, and also why the detector [30x30x1]cm of CdZnTe , does not record of many events
thank you
please help me
