Discussion Overview
The discussion centers on modeling light emission from materials, specifically plastic scintillators, when excited by neutrons using MCNP simulations. Participants seek information on relevant literature and the capabilities of MCNP regarding scintillation and optical emissions.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- One participant inquires about sources for modeling light emission from materials excited by neutrons in MCNP.
- Another participant clarifies whether the discussion pertains to liquid or crystal scintillators for neutron detection.
- It is noted that the material in question is a plastic scintillator with amorphous silicon behind it, raising uncertainty about MCNP's treatment of scintillation.
- A participant questions if the scintillator is borated and provides a reference to a study on a liquid scintillator for neutron spectroscopy.
- One participant expresses their goal to track emitted light from neutron-scintillator interactions, indicating uncertainty about MCNP's ability to calculate optical responses directly.
- A later reply mentions that LANL is developing a toolkit called DRiFT to calculate detector responses, detailing how it treats particles and determines photon production based on energy interactions.
- References to various authors and studies are provided, highlighting the use of MCNP in modeling scintillation detectors, particularly in relation to different neutron interactions.
Areas of Agreement / Disagreement
Participants express uncertainty regarding MCNP's capabilities in modeling scintillation and optical emissions, and there is no consensus on whether MCNP can directly calculate these responses. Multiple viewpoints on the modeling approach and relevant literature remain present.
Contextual Notes
Limitations include the unclear extent to which MCNP accounts for scintillation effects and the specific conditions under which different neutron interactions are modeled.
