88-Inch Cyclotron
88-Inch Cyclotron
Before starting my PhD program, I did research at Lawrence Berkeley National Lab's 88" Cyclotron, working for the Bay Area Neutron Group in UC Berkeley's Department of Nuclear Engineering.
Neutrons... in Berkeley?

Neutrons are produced at the cyclotron by accelerating deuterons up to energies of several MeV, then slamming these onto a target which breaks up the deuterons. After several feet of collimation, a tunable neutron beam is usable in the experimental caves.

This is a simulated (Geant4) version of the proton-recoil neutron detector, when I was experimenting with adding an inner shielding to block background from the Al(n,p) reaction.
