The HOLMES experiment will provide an important step forward in direct neutrino mass measurements with a calorimetric approach as an alternative to spectrometry. HOLMES will perform a calorimetric measurement of the energy released in the decay of163Ho and will deploy a large array of transition-edge sensor microcalorimeters with implanted163Ho nuclei. The resulting mass sensitivity could be as low as 0.4ÃÂ eV, and it will also establish the potential of this approach to extend the sensitivity down to 0.1ÃÂ eV and lower.

Abstract
The HOLMES experiment will provide an important step forward in direct neutrino mass measurements with a calorimetric approach as an alternative to spectrometry. HOLMES will perform a calorimetric measurement of the energy released in the decay of163Ho and will deploy a large array of transition-edge sensor microcalorimeters with implanted163Ho nuclei. The resulting mass sensitivity could be as low as 0.4ÃÂ eV, and it will also establish the potential of this approach to extend the sensitivity down to 0.1ÃÂ eV and lower.
