12. First investigations of the digital pulse processor DP5 for low energy electron measurements with a pin diode

In the Kartin experiment the Forward Beam Monitor Detector is being developed to measure the beta electron spectrum of the electron beam before it enters the main spectrometer. Here a pin diode is used to detect the electrons with an expected high rate of 10^6 1/s mm^2 and low kinetic energies between 0 and 18.6 keV. The high rates cause pile-up effects that lead to unwanted longer dead...

22. Accurate Raman Spectroscopy at the KATRIN Experiment

Neutrinos are by far the lightest fermions in the Standard Model of particle physics and also the most numerous fermionic particles in the Universe. Originally, they were believed to be massless. However, later neutrino oscillation experiments indicated that neutrinos actually carry (some very small) mass, making them the lightest fermions in the Standard Model of particle physics. Their...

9. Usage of (_ ^37)Ar for calibration of large liquid xenon detectors

Standard calibration methods for liquid xenon detectors includes the calibration with external sources of gammas or neutrons. Due to the excellent selfshielding of xenon against radiation, these methods are not usable at large detectors like the upcoming XENON1T or DARWIN experiments. To reach the inner regions of large detectors, radiation sources are needed, which can be induced into the...
