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
