Formula for calculating neutron flux?

Click For Summary

Discussion Overview

The discussion centers around calculating neutron flux in the context of a liquid scintillator experiment involving neutron detection from a reactor. Participants explore the necessary parameters and information required for the calculation.

Discussion Character

  • Exploratory, Technical explanation, Experimental/applied

Main Points Raised

  • One participant seeks a formula for calculating neutron flux but expresses uncertainty about the parameters needed for the calculation.
  • Another participant emphasizes the necessity of obtaining specific values from experiments or reactor operators, indicating that calculation cannot proceed without this information.
  • A further reply requests clarification on which specific parameters are needed to find the neutron flux.
  • Another participant suggests that due to the complexity of the project, it may be more effective to consult someone at the lab who has experience with measuring neutron flux.
  • It is noted that the neutron flux is influenced by various factors, and obtaining it may require either direct measurement or existing data from previous measurements.

Areas of Agreement / Disagreement

Participants generally agree that specific information is necessary for calculating neutron flux, but there is no consensus on the exact parameters needed or how to obtain them.

Contextual Notes

The discussion highlights the dependence on external data sources and the variability of factors influencing neutron flux, which remain unspecified.

I have a liquid scintillator, the electronics system, and a beam of neutrons from a reactor. How do I calculate the neutron flux? Cold anybody give me a formula or equation? Not this equation: phi = n X v, where phi - flux, n = number of neutrons per cm3, v = velocity of the neutrons, because I don't know how to get any of these information. Please Help!

You will need some values from somewhere. From your experiment, from the people operating the reactor, from other detectors - something. You cannot calculate a number without any information.
 
Thanks for your reply! COuld you tell me what those informations/parameters should be so I can go look for those values?
 
From your description, and previous threads, this seems to be fairly high level experimental project. In which case, just ask someone at your lab.

The neutron flux will depend on a bunch of factors, and as mfb points out, you can find it from a variety of places, but it comes down to either measuring it, or asking someone who has already measured it.
