Conversion electrons used to monitor the energy scale of electron spectrometer near tritium endpoint – a simulation study
نویسنده
چکیده
Measurements of the endpoint region of the tritium β–decay spectrum provides good possibility to determine neutrino mass. This, however, needs a perfect monitoring of the spectrometer energy scale. A parallel measurement of electron line of known energy – in particular the 83m Kr conversion K-line – may serve well to this purpose. The 83 Rb decaying to 83m Kr seems to be a very suitable radioactive source due to its halflife of 86.2 day. In this work, we determine the amount of 83 Rb which is necessary for a successful monitoring.

Isotopes 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 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...

Introduction: The goal of any type of radiation therapy in the treatment of tumors, in addition to destroying cancer cells, is to minimizing radiation to nearby healthy cells and thus reducing side damages. For this purpose, targeted radiation therapy (TRT) is more effective in treating of single cells or small cluster of cells. The main factor in the success of this method is...
متن کاملILC Beam Energy Measurement by means of Laser Compton Backscattering
A novel, non-invasive method of measuring the beam energy at the International Linear Collider is proposed. Laser light collides head-on with beam particles and either the energy of the Compton scattered electrons near the kinematic endpoint is measured or the positions of the Compton backscattered γ-rays, the edge electrons and the unscattered beam particles are recorded. A compact layout for ...

The mono-energetic conversion electrons from the decay of 83mKr represent a unique tool for the energy calibration, energy scale monitoring and systematic studies of the tritium beta spectrum measurement in the neutrino mass experiment KATRIN. For this reason, the long term stability of energy of the 7.5 keV and 17.8 keV conversion electrons populated in the decay of solid 83Rb/83mKr vacuum eva...
