Purification Efficiency and Radon Emanation of Gas Purifiers used with Pure and Binary Gas Mixtures for Gaseous Dark Matter Detectors
K., Altenmüller, J. F. Castel +22
Rare event searches require extreme radiopurity in all detector components. This includes the active medium, which in the case of gaseous detectors, is the operating gas. The gases…
The Design, Construction, and Commissioning of the KATRIN Experiment
M. Aker, K. Altenmüller, J. F. Amsbaugh +226
The KArlsruhe TRItium Neutrino (KATRIN) experiment, which aims to make a direct and model-independent determination of the absolute neutrino mass scale, is a complex experiment wit…
Conceptual Design of BabyIAXO, the intermediate stage towards the International Axion Observatory
A. Abeln, K. Altenmüller, S. Arguedas Cuendis +123
This article describes BabyIAXO, an intermediate experimental stage of the International Axion Observatory (IAXO), proposed to be sited at DESY. IAXO is a large-scale axion heliosc…
Characterization of Silicon Drift Detectors with Electrons for the TRISTAN Project
S. Mertens, T. Brunst, M. Korzeczek +30
Sterile neutrinos are a minimal extension of the Standard Model of Particle Physics. A promising model-independent way to search for sterile neutrinos is via high-precision beta sp…
Suppression of Penning discharges between the KATRIN spectrometers
M. Aker, K. Altenmüller, A. Beglarian +151
The KArlsruhe TRItium Neutrino experiment (KATRIN) aims to determine the effective electron (anti)neutrino mass with a sensitivity of (90 C.L.) by precise…
First operation of the KATRIN experiment with tritium
M. Aker, K. Altenmüller, M. Arenz +168
The determination of the neutrino mass is one of the major challenges in astroparticle physics today. Direct neutrino mass experiments, based solely on the kinematics of beta-decay…
High-resolution spectroscopy of gaseous Kr conversion electrons with the KATRIN experiment
K. Altenmüller, M. Arenz, W. -J. Baek +124
In this work, we present the first spectroscopic measurements of conversion electrons originating from the decay of metastable gaseous Kr with the Karlsruhe Tritium…
Gamma-induced background in the KATRIN main spectrometer
K. Altenmüller, M. Arenz, W. -J. Baek +123
The KATRIN experiment aims to measure the effective electron antineutrino mass with a sensitivity of 0.2 eV/c using a gaseous tritium source combined with th…
A novel detector system for KATRIN to search for keV-scale sterile neutrinos
Susanne Mertens, Antonio Alborini, Konrad Altenmüller +19
Sterile neutrinos are a minimal extension of the Standard Model of Particle Physics. If their mass is in the kilo-electron-volt regime, they are viable dark matter candidates. One…
Muon-induced background in the KATRIN main spectrometer
K. Altenmüller, M. Arenz, W. -J. Baek +131
The KArlsruhe TRItium Neutrino (KATRIN) experiment aims to make a model-independent determination of the effective electron antineutrino mass with a sensitivity of 0.2 eV/c.…
The Monte Carlo simulation of the Borexino detector
M. Agostini, K. Altenmuller, S. Appel +97
We describe the Monte Carlo (MC) simulation package of the Borexino detector and discuss the agreement of its output with data. The Borexino MC 'ab initio' simulates the energy los…
