Alpha Spectroscopy Low Energy Error

AI Thread Summary
Low energy peaks in the alpha spectrum of a U238 sample may indicate issues with detector calibration or background interference. Comparing the spectrum to a standard U-238 alpha spectrum can help identify discrepancies. The scale of the abscissa is crucial for accurate interpretation of the data. Visual clarity in the screenshot is important for diagnosing the problem effectively. Accurate analysis will lead to better understanding and resolution of the low energy error.

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.
 

Thread 'MCNP6 BURN Card Issue: Zero Burnup for Material in Fuel Assembly'

Hello everyone, I am currently working on a burnup calculation for a fuel assembly with repeated geometric structures using MCNP6. I have defined two materials (Material 1 and Material 2) which are actually the same material but located in different positions. However, after running the calculation with the BURN card, I am encountering an issue where all burnup information（power fraction(Initial input is 1,but output file is 0), burnup, mass, etc.） for Material 2 is zero, while Material 1...

Thread 'Beginner Seeking Help: MCNP6 Burnup Example (OECD-NEA Benchmark)'

Hi everyone, I'm a complete beginner with MCNP and trying to learn how to perform burnup calculations. Right now, I'm feeling a bit lost and not sure where to start. I found the OECD-NEA Burnup Credit Calculational Criticality Benchmark (Phase I-B) and was wondering if anyone has worked through this specific benchmark using MCNP6? If so, would you be willing to share your MCNP input file for it? Seeing an actual working example would be incredibly helpful for my learning. I'd be really...
