Characterization of a Two-Channel Optical and Near-infrared Transition Edge Sensor System for Rare-Event Searches
Manuel Meyer, Katharina-Sophie Isleif, Friederike Januschek +5
Transition edge sensors (TESs) are superconducting energy-resolving microcalorimeters that have demonstrated low background rates as well as quantum efficiencies close to unity for…
Distributed Acoustic Fiber Sensing for Research Campuses and Large Scientific Infrastructures -- The Hamburg WAVE proto-network
Oliver Bölt, Luigia Cristiano, Sandy Croatto +17
Here, we demonstrate and investigate how Distributed Acoustic Sensing (DAS) can be utilized on research campuses and in large scientific infrastructures to study environmental vibr…
Binary Classification of Light and Dark Time Traces of a Transition Edge Sensor Using Convolutional Neural Networks
Elmeri Rivasto, Katharina-Sophie Isleif, Friederike Januschek +5
The Any Light Particle Search II (ALPS II) is a light shining through a wall experiment probing the existence of axions and axion-like particles using a 1064 nm laser source. While…
First direct search for light dark matter interactions in a transition-edge sensor
Christina Schwemmbauer, Guy Daniel Hadas, Yonit Hochberg +9
We propose the use of transition-edge sensor (TES) single-photon detectors as a simultaneous target and sensor for direct dark matter searches, and report results from the first se…
TES Detector for ALPS II
Rikhav Shah, Katharina-Sophie Isleif, Friederike Januschek +2
The application of cryogenic single photon detectors has found great use in high precision particle physics experiments such as ALPS (Any Light Particle Search) II, which implement…
Towards the LISA Backlink: Experiment design for comparing optical phase reference distribution systems
Katharina-Sophie Isleif, Lea Bischof, Stefan Ast +11
LISA is a proposed space-based laser interferometer detecting gravitational waves by measuring distances between free-floating test masses housed in three satellites in a triangula…
Laser-Frequency Stabilization via a Quasimonolithic Mach-Zehnder Interferometer with Arms of Unequal Length and Balanced dc Readout
Oliver Gerberding, Katharina-Sophie Isleif, Moritz Mehmet +2
Low frequency high precision laser interferometry is subject to excess laser-frequency-noise coupling via arm-length differences which is commonly mitigated by locking the frequenc…
