Description
Sterile neutrinos are a natural extension of the Standard Model of
particle physics. If their mass is in the keV range, they are a viable
dark matter candidate. One way to search for sterile neutrinos in
a laboratory-based experiment is via tritium beta decay. A sterile
neutrino with a mass up to 18.6 keV would manifest itself in the decay
spectrum as a kink-like distortion. The objective of the TRISTAN
project is to extend the KATRIN experiment with a novel multi-pixel
silicon drift detector and readout system to search for a keV-scale
sterile neutrino signal. This talk will give an overview on the current
status of the project with an emphasis on the detector performance.
Characterization measurement results obtained with a 166-pixel
system will be shown.
