Test of potential homogeneity in the KATRIN gaseous tritium source
نویسنده
چکیده
Kr is supposed to be used to study the properties of the windowless gaseous tritium source of the experiment KATRIN. In this work we deduce the amount of Kr which is necessary to determine possible potential inhomogeneities via conversion-electron-line broadening. PACS: 29.30.Dn, 07.81.+a, 02.50.-r

KATRIN: an experiment to determine the neutrino mass from the beta decay of tritium
for the KATRIN Collaboration Abstract KATRIN is a very large scale tritium-beta-decay experiment to determine the mass of the neutrino. It is presently under construction at the Karlsruhe Institute of Technology north campus, and makes use of the Karlsruhe Tritium Laboratory built as a prototype for the ITER project. The combination of a large retarding-potential electrostatic-magnetic spectrom...
متن کاملStatus of the KATRIN experiment
The aim of the Karlsruhe Tritium Neutrino experiment-KATRIN-is the direct measurement of the anti-neutrino mass with a sensitivity of 200 meV/c 2 (90% C.L.). It is based on the study of the endpoint region of tritium β decay where a non-vanishing anti-neutrino mass causes a distortion of the β spectrum. KATRIN will allow to probe a part of the cosmology-relevant neutrino mass parameter space an...
متن کاملThe KATRIN sensitivity to the neutrino mass and to right-handed currents in beta decay
The aim of the KArlsruhe TRItium Neutrino experiment KATRIN is the determination of the absolute neutrino mass scale down to 0.2 eV, with essentially smaller model dependence than from cosmology and neutrinoless double beta decay. For this purpose, the integral electron energy spectrum is measured close to the endpoint of molecular tritium beta decay. The endpoint, together with the neutrino ma...
متن کاملIsotopes for fundamental research in 83Kr for KATRIN
6 Contents Introduction The advantage of radioisotopic standards compared to other physical standards is the independence of their properties from outer conditions. They are neither sensitive to temperature change nor to progress of time. They serve as influence-free-etalon. That is why their use is advantageous in fundamental research, where high precision is required. For instance in direct n...
متن کاملEnvironmental tritium contamination from a gaseous tritium light device maintenance facility
An investigation was undertaken in relation to the contamination of a facility used for the servicing and refurbishment of gaseous tritium light devices. While it is generally accepted that there is minimal exposure hazard from a broken gaseous tritium light source after the tritium gas has dispersed, environmental tritium contamination displaying ‘particulate’ like characteristics was observed...
