The recent redefinition of the kilogram provides encouragement for widespread adoption of primary methods to realise the kilogram. To support this, NPL is building a “next generation” Kibble balance which, by eliminating the need for careful alig

Thermal management on space vehicles is dominated by passive systems, including materials, coatings, louvers and heat pipes, and active systems, including pumped liquid loops. Recently, the pulse thermal loop was proposed as a novel technology to pro

An ejector-based pulse refrigeration system (PRS) t hat may be powered by solar or waste heat, and which is suitable for terrestrial and mic ro-gravity environments was previously proposed. This paper addresses the design of the ej ector for the PRS
