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.

Hi there,

I'm sorry to hear that you're having trouble with your sodium iodide detector on MCNP. It sounds like you have already tried modifying your SDEF card, but it's still not working. Have you checked to make sure that your source is properly defined and placed in the correct location? Sometimes even small errors in placement can affect the results.

Another thing you could try is checking your geometry and making sure that there are no overlapping cells or other issues that could be causing the source to not reach the detector. You could also try using a different type of source, such as a point source, to see if that makes a difference.

If all else fails, I would recommend reaching out to the MCNP community for help. There are many experienced users who may be able to offer some insights or tips on how to troubleshoot your issue. Good luck!
