SUMMARY

The discussion centers on achieving a neutron flux greater than 5e8 n/sqcm.second in a Beam Shape Assembly (BSA) setup, specifically within a beryllium sphere. The user is conducting Boron Neutron Capture Therapy (BNCT) and seeks to measure the neutron flux at the end of cell 7, with a neutron production source located in cell 3. The conversation also touches on the configuration involving lithium-7 on copper and alumina within an iron container in a hydrogen-filled environment.

PREREQUISITES
  • Understanding of neutron flux measurement techniques
  • Familiarity with Boron Neutron Capture Therapy (BNCT)
  • Knowledge of Beam Shape Assembly (BSA) configurations
  • Basic principles of neutron production and particle physics
NEXT STEPS
  • Research neutron flux measurement methods in BNCT applications
  • Explore simulation techniques for neutron behavior in beryllium spheres
  • Investigate the effects of lithium-7 on neutron capture rates
  • Learn about the design and optimization of Beam Shape Assemblies
USEFUL FOR

Medical physicists, researchers in neutron therapy, and professionals involved in particle physics and radiation therapy optimization will benefit from this discussion.

Hi
this is the attached file . i want to get the flux at the end of BSA which is cell 7 also the flux of cell 8 is less than 5e8. now my target is to get the flux greater than 5e8. thank you to all

You have a target of lithium-7 on copper on alumina etc inside an iron container inside a hydrogen filled space in a large beryllium sphere. Is that right?

You want the neutron flux in the beryllium sphere to exceed 5e8 n/sqcm.second? What is the activity of the neutron source?

What does BSA mean please?

yes you are right. BSA means " Beam Shape Assembly" . and you are right i want flux 5e8. acutually i am doing Boron neutron capture therapy
 
It might be more normal to simulate for a flux inside some sort of tissue. But you have a sphere of BeO, and you want a flux of 5e8 in it, and it's 6 meters in diameter?

What is the rate of particle production in the source?
 
my neutrons production is in cell 3 and i need the flux at the end of the cell 7
