Finding Resolution for PIPS Detector Using Am-241 Source

Click For Summary
The discussion focuses on determining the resolution of a PIPS detector using an Am-241 source, which presents challenges due to closely spaced alpha-peaks at 5442.80 keV and 5485.56 keV. The user has experience with Ge detectors but finds the current measurement more complex. They mention that increasing the amplifier gain is not feasible as it causes peak loss in the spectrum. Adjusting the zero level of the ADC has not yielded any improvements to the peaks. The setup involves a PIPS preamp, amplifier, ADC, data system, and LabVIEW for data analysis.

Homework Statement


Determining the resolution for a new PIPS (Passivated Implanted Planar Silicon) detector. I've done this earlier for a Ge detector, but that was easy because the two peaks of the Co-60 are far apart.

For this measurement we use the normal Am-241 source which has two alpha-peaks at 5442.80 keV and 5485.56 keV. The only things I now I can do for raising the resolution is adjusting the gain at the amplifier and adjusting the zero level of the ADC.

I can't turn the gain higher, because the peak will fall of the spectrum. Adjusting the zero level apparently does nothing to the peaks.

The electronics are just: PIPS-preamp-amp-ADC-Data system-Labview
