Removing krypton from xenon by cryogenic distillation to the ppq level [PDF]

The European Physical Journal C, 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 ...

Krypton assay in xenon at the ppq level using a gas chromatographic system and mass spectrometer [PDF]

, 2014
We have developed a new method to measure krypton traces in xenon at unprecedented low concentrations. This is a mandatory task for many near-future low-background particle physics detectors.

Radiation-resistant metal-organic framework enables efficient separation of krypton fission gas from spent nuclear fuel

Nature Communications, 2020
Management of spent nuclear fuel is challenging due to the release of volatile radionuclides. Here the authors report krypton separation from fission gas in the presence of other competing gases by a radiation resistant metal-organic framework using the ...

Krypton oxides under pressure [PDF]

Scientific Reports, 2016
AbstractUnder high pressure, krypton, one of the most inert elements is predicted to become sufficiently reactive to form a new class of krypton compounds; krypton oxides. Using modern ab-initio evolutionary algorithms in combination with Density Functional Theory, we predict the existence of several thermodynamically stable Kr/O species at elevated ...

Experimental Investigations of a Krypton Stationary Plasma Thruster

International Journal of Aerospace Engineering, 2013
Stationary plasma thrusters are attractive electric propulsion systems for spacecrafts. The usual propellant is xenon. Among the other suggested propellants, krypton could be one of the best candidates.

Application and modeling of an online distillation method to reduce krypton and argon in XENON1T [PDF]

, 2021
A novel online distillation technique was developed for the XENON1T dark matter experiment to reduce intrinsic background components more volatile than xenon, such as krypton or argon, while the detector was operating. The method is based on a continuous

Performance comparison of a 9-kW magnetically shielded Hall thruster operating on xenon and krypton

Journal of Applied Physics, 2021
The performance of a 9-kW class magnetically shielded Hall thruster operating on xenon and krypton propellants is experimentally char-acterized. Thrust and efficiency measurements performed at discharge powers ranging from 4.5 to 9 kW indicate that the ...

Advancement of radioactive material removal system by silver zeolite (Quantitative evaluation of noble gas adsorption characteristics by XeA and construction of noble gas adsorption system)

Nihon Kikai Gakkai ronbunshu, 2022
In nuclear power plants, measures against radioactive noble gases are required. Until now, special activated carbon that easily adsorbs noble gases has been used in some nuclear facilities. However, activated carbon has a small adsorption capacity and is
