Characterization of a prototype parallel-plate ${}^{238}$U fission chamber with DD and DT fusion neutron sources

V. Hagenlocker, R. A. Tinguely, X. Wang +5

The SPARC tokamak will employ ${}^{238}$U-based fission chambers (FCs) to monitor high-performance deuterium-tritium (DT) plasma operations, spanning neutron yield rates from ${\sim}…
