Abstract The Karlsruhe Tritium Neutrino (KATRIN) experiment is designed to measure a high-
precision integral spectrum of the endpoint region of T 2 β decay, with the primary goal of …

We present the first experimental results achieved with a monolithic array of 166 Silicon Drift
Detectors (SDD). This detector was developed for the TRISTAN experiment, targeting the …

The TRISTAN detector is a new detector for electron spectroscopy at the Karlsruhe Tritium
Neutrino (KATRIN) experiment. The semiconductor detector utilizes the silicon drift detector …

We challenge the traditional wisdom that cosmological (big bang relic) neutrinos can only be
hot Dark Matter. We provide a critical review of the concepts, derivations and arguments in …

We present a silicon drift detector (SDD) system for the spectroscopy focusing array (SFA) of
the enhanced X-ray timing and polarimetry (eXTP) mission. The SFA focuses on fast timing …

Sterile neutrinos are a minimal extension of the standard model of particle physics. A
laboratory-based approach to search for this particle is via tritium β-decay, where a sterile …

We challenge the traditional wisdom that cosmological (big bang relic) neutrinos can only be
hot Dark Matter. We provide a critical review of the concepts, derivations and arguments in …

An array of 9 detectors based on monolithic arrays of 166 Silicon Drift Detectors (SDD) will
be installed in 2026 in the KATRIN experiment for the search of sterile neutrinos in the keV …

We present the ASPECT-BET project developing a dual-channel SDD-based spectrometer
designed to achieve high-precision measurements of beta decays across a broad energy …

This paper presents an analog event processing and acquisition platform, primarily targeting
X-ray and electron spectroscopy. It allows the simultaneous acquisition of 48 channels, each …
