Influence of the characteristics of the working fluids of an electric jet engine on the energy and design parameters of a space vehicle during launch into geostationary orbit [PDF]
Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроениеThis paper examines the use of electric propulsion engines using krypton as the propellant for launching payloads into geostationary orbit. Key aspects of using electric propulsion engines using xenon and krypton as propellants are presented.

Removing krypton from xenon by cryogenic distillation to the ppq level [PDF]
, 2017 The XENON1T experiment aims for the direct detection of dark matter in a cryostat filled with 3.3 tons of liquid xenon. In order to achieve the desired sensitivity, the background induced by radioactive decays inside the detector has to be sufficiently ...

A novel vacuum ultra violet lamp for metastable rare gas experiments [PDF]
, 2002 We report on a new design of a vacuum ultra violet (VUV) lamp for direct optical excitation of high laying atomic states e.g. for excitation of metastable rare gas atoms. The lamp can be directly mounted to ultra high vacuum vessels (p
