What Code Can Predict Neutron and Gamma Yields from an AmBe Source?

Click For Summary
SUMMARY

This discussion centers on the need for a code that can accurately predict neutron and gamma yields from an Americium-Beryllium (AmBe) source. Participants reference a specific paper from the National Institute of Standards and Technology (NIST) and an IAEA publication that may provide relevant calculations. Key questions include the definition of radiation efficiency and the quantification of neutron and gamma production per curie of Am. The discussion highlights the importance of calibrated curves in these calculations.

PREREQUISITES
  • Understanding of neutron and gamma radiation principles
  • Familiarity with AmBe neutron sources
  • Knowledge of radiation efficiency concepts
  • Ability to interpret scientific papers and references
NEXT STEPS
  • Research the NIST publication on neutron spectra for AmBe sources
  • Examine the IAEA Technical Report Series No. 403 for detailed calculations
  • Learn about radiation efficiency metrics in nuclear physics
  • Explore software tools for simulating neutron and gamma yields
USEFUL FOR

Researchers in nuclear physics, radiation safety professionals, and anyone involved in the study or application of AmBe neutron sources will benefit from this discussion.

Hello,

does anyone know of a code that will generate the expected neutron spectrum for an AmBe neutron source along with the expected reaction efficiency?
 
Engineering news on Phys.org
Here is a paper that references a calculation, but the referenced citation is not so clear. Perhaps they refer to using a calibrated curve.

http://nvl.nist.gov/pub/nistpubs/jres/111/6/V111.N06.A02.pdf (cites Ref. 12)

Ref 12: www-pub.iaea.org/MTCD/publications/PDF/TRS403_scr.pdf


What does one mean by radiation efficiency?
 
For every currie of Am I have, how many neutrons will be produced? how many gammas will be produced?
