Energy, vertex, and time response of a LiquidO detector with an opaque-scintillator target to Compton-tagged electrons
LiquidO Collaboration, S. Katz, J. T. Moffatt +89
LiquidO detectors confine scintillation light near its point of production by stochastic scattering in an opaque medium and collect it with a lattice of wavelength-shifting (WLS) f…
Characterization of a radiation detector based on opaque water-based liquid scintillator
LiquidO Collaboration
We present the characterization of a novel radiation detector based on an opaque water-based liquid scintillator. Opaque scintillators, also known as LiquidO, are made to be highly…
Using Micromegas detectors for direct dark matter searches: challenges and perspectives
K. Altenmueller, . Antolin, D. Calvet +27
Gas time projection chambers (TPCs) with Micromegas pixelated readouts are being used in dark matter searches and other rare event searches, due to their potential in terms of low…
Searching for WIMPs with TREX-DM: achievements and challenges
Juan F. Castel, Susana Cebrián, Theopisti Dafni +15
The TREX-DM detector, a low background chamber with microbulk Micromegas readout, was commissioned in the underground laboratory of Canfranc (LSC) in 2018. Since then, data taking…
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…
TREX-DM: a low background Micromegas-based TPC for low-mass WIMP detection
F. J. Iguaz, J. G. Garza, F. Aznar +8
Dark Matter experiments are recently focusing their detection techniques in low-mass WIMPs, which requires the use of light elements and low energy threshold. In this context, we d…
Gaseous time projection chambers for rare event detection: Results from the T-REX project. I. Double beta decay
I. G. Irastorza, F. Aznar, J. Castel +13
As part of the T-REX project, a number of R&D and prototyping activities have been carried out during the last years to explore the applicability of gaseous Micromegas-read TPCs in…
TREX-DM: a low-background Micromegas-based TPC for low-mass WIMP detection
F. J. Iguaz, J. G. Garza, F. Aznar +8
If Dark Matter is made of Weakly Interacting Massive Particles (WIMPs) with masses below 20 GeV, the corresponding nuclear recoils in mainstream WIMP experiments are of energ…
A Micromegas-based low-background x-ray detector coupled to a slumped-glass telescope for axion research
