Discussion Overview

The discussion revolves around challenges faced by a participant in writing an input deck for MCNP to calculate fluence in a zinc sulphide scintillator, specifically involving alpha particles emitted from a plutonium-containing solution. The scope includes technical aspects of geometry, cell cards, ZAID numbers, and SDEF cards.

Discussion Character

  • Technical explanation, Homework-related, Debate/contested

Main Points Raised

  • The initial poster expresses uncertainty about the correctness of their geometry in the MCNP input deck.
  • There is confusion regarding what to include in the cell card for alpha particles, specifically the "imp:?" parameter.
  • The poster is unsure about the appropriate ZAID numbers to use in their calculations.
  • Questions are raised about the SDEF card for defining a volume source.
  • One participant notes that they had previously responded to some of the poster's questions in a private message but feels the poster's new post does not add new information.
  • The poster questions whether their geometry is confusing, indicating a need for clarification.

Areas of Agreement / Disagreement

The discussion remains unresolved, with multiple competing views and uncertainties expressed regarding the technical aspects of the MCNP input deck.

Contextual Notes

Limitations include the poster's lack of clarity on specific parameters and potential dependencies on definitions related to MCNP usage.

I don't have anyone in my university who can help me with MCNP. I'm trying to write an input deck to calculate fluence in a zinc sulphide scintillator. The alpha particles are being emitted from a solution containing plutonium, plutonium nitrate and plutonium nitride.

There are lots of things I don't understand. I am not sure if my geometry is correct. I am not sure what to put in the cell card for alpha particles "imp:?". I am unsure about the ZAID numbers and the SDEF card for a volume source. Any help to get this working would be appreciated :frown:

Hi,
I think that I I had answered of some of your question in "inbox" but I see that you ask the same question
I will wait the reponse that you will have with this new post
bye

Hi,

I don't think you added anything new in the inbox reply?

First I would like to address the cell and surface cards. I think my geometry is correct, but is it confusing?
