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?
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?
