Description
We developed a simple small-scale experiment to measure the beta decay spectrum of $^{3}$H. This research aims to investigate the presence of sterile neutrinos in the keV region. Tritium nuclei were embedded in a 1$\times$1$\times$1 cm$^3$ LiF crystal from the $^6$Li(n,$\alpha$)$^3$H reaction. The energy of the beta electrons absorbed in the LiF crystal was measured with a magnetic micro-calorimeter at mK temperatures. We present the current status of the experiment including the energy calibration study. Moreover, we present the project plans for $^{3}$H measurement and their expected sensitivities for keV sterile neutrino search.
