Design, construction and commissioning of a high-flow radon removal system for XENONnT
M. Murra, D. Schulte, C. Huhmann +1
A high-flow radon removal system based on cryogenic distillation was developed and constructed to reduce radon-induced backgrounds in liquid xenon detectors for rare event searches…
Reflectivity of VUV-sensitive Silicon Photomultipliers in Liquid Xenon
M. Wagenpfeil, T. Ziegler, J. Schneider +140
Silicon photomultipliers are regarded as a very promising technology for next-generation, cutting-edge detectors for low-background experiments in particle physics. This work prese…
Application and modeling of an online distillation method to reduce krypton and argon in XENON1T
E. Aprile, K. Abe, F. Agostini +151
A novel online distillation technique was developed for the XENON1T dark matter experiment to reduce intrinsic background components more volatile than xenon, such as krypton or ar…
Ultra-clean radon-free four cylinder magnetically-coupled piston pump
D. Schulte, M. Murra, P. Schulte +2
A high performance gas displacement pump based on four individual cylinders was developed. The magnetically-coupled pistons and the hermetically-sealed housings as well as the spec…
Electro-purification studies and first measurement of relative permittivity of TMBi
S. Peters, B. Gerke, V. Hannen +6
A new type of detector for positron-emission tomography (PET) has been proposed recently, using a heavy organo-metallic liquid - TriMethyl Bismuth (TMBi) - as target material. TMBi…
Proof-of-concept of a xenon-based cryogenic heat pump demonstrator for future liquid xenon observatories
P. Schulte, D. Wenz, L. Althueser +7
This manuscript details the proof-of-concept of a small-scale cryogenic heat pump demonstrator, a technology designed to enable high-flow xenon distillation systems for the removal…
Cryogenic bath-type heat exchangers for ultra-pure noble gas applications
M. Murra, D. Schulte, I. Cristescu +4
Two cryogenic bath-type heat exchangers for ultra-pure noble gas applications were developed with particular emphasis on noble gas liquefaction in cryogenic distillation systems. T…
A novel Kr tracer method for characterizing xenon gas and cryogenic distillation systems
S. Rosendahl, K. Bokeloh, E. Brown +9
The radioactive isomer Kr has many properties that make it very useful for various applications. Its low energy decay products, like conversion, shake-off and Auge…
The XENONnT Dark Matter Experiment
XENON Collaboration, E. Aprile, J. Aalbers +192
The multi-staged XENON program at INFN Laboratori Nazionali del Gran Sasso aims to detect dark matter with two-phase liquid xenon time projection chambers of increasing size and se…
The XENON1T Dark Matter Experiment
XENON Collaboration, E. Aprile, J. Aalbers +142
The XENON1T experiment at the Laboratori Nazionali del Gran Sasso (LNGS) is the first WIMP dark matter detector operating with a liquid xenon target mass above the ton-scale. Out o…
