Short-lived isomer 83m Kr with its discrete electron spectrum has ideal properties to be used in the crucial role of calibration source in low energy experiments like KATRIN or XENON. To ensure smooth long-term operation of these experiments, reliable routines for production of 83 Rb, which decays to 83m Kr, have to be developed. We describe the methods developed at the Nuclear Physics Institute of the Czech Academy of Sciences at Rez, where 83 Rb sources are created for KATRIN predominantly via the reaction 84 Kr(p,2n) 83 Rb by colliding accelerated protons with a target filled with natural krypton gas.

“…Due to the low energy and high multipolarity (E3 for the 32.2 keV transition) of the transitions, the intense conversion electrons are emitted. These monoenergetic electrons are extensively used for the calibration and systematic measurements in the neutrino mass experiments (KATRIN, Project 8) [1,2], dark matter experiments [3,4] and also in the ALICE and COHERENT projects [5,6]. In all these experiments the 83 Rb is deposited into a suitable substrate, from which the daughter 83m Kr emanates.…”

Radioactive sources of the monoenergetic low-energy conversion electrons from the decay of isomeric $$^{83\textrm{m}}\mathrm {{Kr}}$$ 83 m Kr are frequently used in the systematic measurements, particularly in the neutrino mass and dark matter experiments. For this purpose, the isomer is obtained by the decay of its parent radionuclide $$^{83}\mathrm {{Rb}}$$ 83 Rb . In order to get more precise data on the gamma-rays occuring in the $$^{83}\mathrm {{Rb}}$$ 83 Rb /$$^{83\textrm{m}}\mathrm {{Kr}}$$ 83 m Kr chain, we re-measured the relevant gamma-ray spectra, because the previous measurement took place in 1976. The obtained intensities are in fair agreement with the previous measurement. We have, however, improved the uncertainties by a factor of 4.3, identified a new gamma transition and determined more precisely energies of weaker gamma transitions.

“…In order to study the waveform shape dependence at different xenon concentrations, 511 keV γ-rays emitted from the 22 Na radioactive source is used to calibrate the detector. 83m Kr is considered to be an ideal calibration source for liquid noble gas detector because it is a low-energy source and can be easily injected into detectors without any contamination [25][26][27]. The 83m Kr source comes from decay of 83 Rb, which can be obtained by high speed proton hitting natural krypton gas.…”

We have measured the properties of scintillation light in liquid argon doped with xenon concentrations from 165 ppm to 10,010 ppm using a 22 Na source. The energy transfer processes in the xenon-doped liquid argon are discussed in detail, and a new waveform model is established and used to fit the average waveform. The time profile of the scintillation photon in the xenon-doped liquid argon and of the TPB emission are presented. The quantities of xenon-doped are controlled by a Mass Flow Controller which is calibrated via a Redusial Gas Analyzer to ensure that the xenon concentration is accurate. In addition, a successful test of 83m Kr as a calibration source has been implemented in the xenon-doped liquid argon detector for the first time. By comparing the light yield of the 22 Na and 83m Kr, it can be concluded that the scintillation efficiency is almost same over the range of 41.5 keV to 511 keV.
