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...

Conceptual design of the electron-optics of the magnetic electron recoil gamma-ray spectrometer.

In nuclear fusion reactors, deuterium and tritium are fused together. Most reactions produce a 4He ion and a 14 MeV neutron, while about 2 × 10-5 of them produce a 5He ion and a gamma photon. One of the most important measurements from a fusion reactor is the total fusion power, which can be measured using the 14 MeV n...

Bayesian profile reconstruction from multi-monochromatic imager data.

The multi-monochromatic imager (MMI) is a diagnostic instrument that provides spectrally resolved images of inertial confinement fusion experiments centered on emission/absorption from the characteristic lines of mid-Z dopants. Previous methods of analysis required some form of binning across either spectral or spatial...
