MCNP6 Disc Source Setup: Troubleshoot 0 Counts

Click For Summary
SUMMARY

The forum discussion centers on troubleshooting a sodium iodide detector setup in MCNP6, specifically regarding a disc source configuration. The user reports receiving zero counts, indicating that the source is not effectively reaching the detector. Despite multiple modifications to the SDEF card, the issue persists. The community suggests reviewing the input file for potential errors that may be causing the lack of detection.

PREREQUISITES
  • Understanding of MCNP6 simulation software
  • Familiarity with SDEF card configurations
  • Knowledge of sodium iodide detector principles
  • Basic skills in interpreting simulation input files
NEXT STEPS
  • Review MCNP6 documentation on SDEF card parameters
  • Examine input file syntax for potential errors
  • Research sodium iodide detector calibration techniques
  • Explore common troubleshooting methods for MCNP simulations
USEFUL FOR

Researchers and engineers working with radiation detection, MCNP6 users, and anyone involved in simulating detector responses in nuclear physics applications.

I am attempting to build a sodium iodide detector on MCNP.
I am using a disc source and I have been trying to define it in terms of a cell that I placed underneath the detector. When I run it, I get 0's for my counts. This indicates to me that my source isn't hitting my detector. I keep modifying my SDEF card but it doesn't help. I am not sure what else to do. Please tell me what could me wrong.
