Detector Development for a Sterile Neutrino Search with the KATRIN Experiment

The KATRIN (Karlsruhe Tritium Neutrino) experiment investigates the energetic endpoint of the tritium \(\beta\)-decay spectrum to determine the effective mass of the electron anti-neutrino with a precision of \(200\,\mathrm{meV}\) (\(90\,\%\) C.L.) after an effective data taking time of three years....

Description
Summary:The KATRIN (Karlsruhe Tritium Neutrino) experiment investigates the energetic endpoint of the tritium \(\beta\)-decay spectrum to determine the effective mass of the electron anti-neutrino with a precision of \(200\,\mathrm{meV}\) (\(90\,\%\) C.L.) after an effective data taking time of three years. The TRISTAN (tritium \(\beta\)-decay to search for sterile neutrinos) group aims to detect a sterile neutrino signature by measuring the entire tritium \(\beta\)-decay spectrum with an upgraded KATRIN system. One of the greatest challenges is to handle the high signal rates generated by the strong activity of the KATRIN tritium source. Therefore, a novel multi-pixel silicon drift detector is being designed, which is able to handle rates up to \(10^{8}\,\mathrm{cps}\) with an excellent energy resolution of \(
