Influence of Annealing on the Optical and Scintillation Properties of CaWO$_4$ Single Crystals

, 2012
We investigate the influence of oxygen annealing on the room temperature optical and scintillation properties of CaWO$_4$ single crystals that are being produced for direct Dark Matter search experiments.

Analysis and modelling for CRESST-II

, 2012
The dark matter search CRESST-II completed its most recent run, Run 32, in 2011. Compared to previous runs, the quantity of data taken in this run increased significantly. In this work, Oxrop, analysis software in use within the CRESST collaboration, is upgraded to analyse this new data.

Light dark matter investigation with CRESST [PDF]

Proceedings of Neutrino Oscillation Workshop — PoS(NOW2018), 2019
Cryogenic detectors are excellent devices for rare event searches. Thanks to their low energy thresholds, these detectors are at the cutting edge for the investigations of light dark matter (DM). The CRESST (Cryogenic Rare Event Search with Superconducting Thermometers) experiment explores with high sensitivity the parameter space of low mass DM ...

Detection of Asymmetry in the Narrow Fe Kα Emission Line in MCG-5-23-16 with Chandra

The Astrophysical Journal
Iron K α (Fe K α ) emission is observed ubiquitously in active galactic nuclei (AGN), and it is a powerful probe of their circumnuclear environment. Examinations of the emission line play a pivotal role in understanding the disk geometry surrounding ...

The $\nu$-cleus experiment: A gram-scale fiducial-volume cryogenic detector for the first detection of coherent neutrino-nucleus scattering

, 2017
We discuss a small-scale experiment, called $\nu$-cleus, for the first detection of coherent neutrino-nucleus scattering by probing nuclear-recoil energies down to the 10 eV-regime.

Constraints on self-interaction cross-sections of dark matter in universal bound states from direct detection

European Physical Journal C: Particles and Fields
$$\varLambda $$ Λ -Cold Dark Matter ( $$\varLambda $$ Λ CDM) has been successful at explaining the large-scale structures in the universe but faces severe issues on smaller scales when compared to observations.

Integrating Out Astrophysical Uncertainties

, 2011
Underground searches for dark matter involve a complicated interplay of particle physics, nuclear physics, atomic physics and astrophysics. We attempt to remove the uncertainties associated with astrophysics by developing the means to map the observed ...

Dark matter search with CRESST-II

, 2011
The CRESST-II Dark Matter experiment aims at the direct detection of WIMPs via scattering off nuclei in CaWO$_4$ crystals which are operated as cryogenic detectors. The phonon signal and the scintillation light signal are recorded simultaneously. The light output of these crystals is used for active discrimination between background events and possible

Exothermic Dark Matter

, 2010
We propose a novel mechanism for dark matter to explain the observed annual modulation signal at DAMA/LIBRA which avoids existing constraints from every other dark matter direct detection experiment including CRESST, CDMS, and XENON10.

Multichannel SQUID readout for CRESST II

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2004
We have developed a 66-channel SQUID system to read out the detectors for the second phase of the CRESST dark matter search using SQUID sensors, electronics and cryocables supplied by different manufacturers. The system has been extensively tested at Oxford to characterise the sensitivity, bandwidth, slew rate, noise, thermal drift, and crosstalk.
