Alpha Spectroscopy Low Energy Error

Click For Summary
SUMMARY

The forum discussion centers on the low energy error observed in alpha spectroscopy of a U-238 sample. Users recommend comparing the spectrum to a standard alpha spectrum of U-238 to identify potential discrepancies. The issue may stem from calibration errors or detector sensitivity at low energy levels. Accurate interpretation of the abscissa scale is crucial for diagnosing the problem.

PREREQUISITES
  • Understanding of alpha spectroscopy techniques
  • Familiarity with U-238 standard spectra
  • Knowledge of detector calibration methods
  • Ability to interpret spectral data and abscissa scales
NEXT STEPS
  • Research standard alpha spectra for U-238
  • Learn about detector calibration techniques in alpha spectroscopy
  • Investigate common sources of low energy errors in spectroscopy
  • Explore software tools for spectral analysis and comparison
USEFUL FOR

This discussion is beneficial for nuclear physicists, spectroscopy researchers, and laboratory technicians involved in alpha particle detection and analysis.

Hello,

I've taken a spectrum of a U238 sample, and I keep getting this hill of low energy values. Any ideas as to what could be causing them?

Sorry about the weird screenshot; it's the only one I had and my friend couldn't see the dots, so i had to go over them in paint.

What is the scale of the abscissa?

I would suggest comparing it to a standard alpha spectrum of U-238.
