Hi there,(adsbygoogle = window.adsbygoogle || []).push({});

So I am doing this lab write-up at the moment with a single channel analyser. The following diagram pretty much sums up the setup:

So pretty much I have found a suitable operating voltage gain by recording number of counts vs. gain and now I must change the Baseline-E (assumedly the centre of the "window" of energies analysed) and plot the number of counts. So I have got the following plot:

I must deduce the differential pulse height spectrum from this graph. I haven't really been introduced to this concept but have done a bit of reading, but generally most of the graphs I see use the multichannel analyser.

Could anyone help me out and desribe how I can find the DPHS from this plot?

Thank you very much.
