Abstract
MetroBeta is a European project aiming at the improvement of the knowledge of the shapes of beta spectra, both in terms of theoretical calculations and measurements. It is part of a common European program of ionizing radiation metrology. Metallic magnetic calorimeters (MMCs) with the beta emitter embedded in the absorber have in the past proven to be among the best beta spectrometers, in particular for low-energy beta transitions. Within this project, new designs of MMCs optimized for five different beta energy ranges were developed. A new detector module with thermal decoupling of MMC and SQUID chips was designed. An important aspect of the research and development concerns the source/absorber preparation techniques. Four beta spectra with maximum energies ranging from 76 to 709 keV will be measured. Improved theoretical calculation methods and complementary measurement techniques complete the project.

N1 - Funding information: Fig. 2 Beta spectrum of 14C, measured with an MMC (rugged, blue line), and calculated using the code BetaShape (smooth, red line). Three discrete photon lines from a 109Cd source external to the detector were used for energy calibration. The electrons from the 109Cd source were screened by a beryllium disk (Color figure online) Acknowledgements This work was performed as part of the EMPIR Project 15SIB10 MetroBeta. The project has received funding from the EMPIR program co-financed by the Participating States and from the European Union’s Horizon 2020 research and innovation program.
