In-Line Process Tritium Monitors

In-line process tritium monitors have been designed, fabricated, and tested for process and experimental applications in the Tritium Laboratory at Ontario Hydro. The monitors are uniquely simple and compact in design, ultrahigh vacuum compatible, and bakeable to 300°C. The low level and medium level tritium monitors with minimum detection limits of the order of 1 and 10 µCi m⁻³, respectively, have linear responses spanning more than 6 decades in concentration, are flow independent to at least 0.5 L s⁻¹, and exhibit small memory effects with rapid recovery following short duration tritium exposures.
