Differential Pulse Height Spectrum

Click For Summary
SUMMARY

The discussion centers on the process of deducing the Differential Pulse Height Spectrum (DPHS) using a single channel analyser. The user, Lachy, has successfully recorded the number of counts against gain and is now focused on adjusting the Baseline-E to analyze energy windows. The challenge lies in extracting the DPHS from the provided graph, which is typically associated with multichannel analysers. Expert guidance is sought to clarify the methodology for deriving the DPHS from the current data.

PREREQUISITES
  • Understanding of Differential Pulse Height Spectrum (DPHS)
  • Familiarity with single channel analysers
  • Knowledge of Baseline-E adjustments in spectroscopy
  • Basic graph interpretation skills in experimental physics
NEXT STEPS
  • Research methods for extracting DPHS from single channel analyser data

Hi there,
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.

Maybe you can get this moved to NUCLEAR ENGINEERING where some experts are more likely to se it??
