Impact of instrumental effects and target thickness on the SPARC magnetic proton recoil spectrometer response function.
The SPARC tokamak aims to demonstrate net fusion power gain in tokamaks (Q-fus > 1). To measure neutron emission, a neutron spectrometer based on the magnetic proton recoil technique is being developed. This diagnostic operates by converting collimated neutrons into recoil protons through elastic scattering on a polyet...
