Neutral tritium gas reduction in the KATRIN differential pumping sections [PDF]

Vacuum, 2020
The KArlsruhe TRItium Neutrino experiment (KATRIN) aims to measure the effective electron anti-neutrino mass with an unprecedented sensitivity of $0.2\,\mathrm{eV}/\mathrm{c}^2$, using $\beta$-electrons from tritium decay.

Tritium burn efficiency in deuterium–tritium magnetic fusion

Nuclear Fusion, 2023
Abstract The controlling parameters regarding tritium burn efficiency (TBE) are derived from first principles and shown to depend fundamentally on the permitted He gas fraction in the divertor and effective pumping speeds of He ash and unburned hydrogenic fuel.
