Dark matter search with CRESST cryogenic detectors

PHYS ATOM NUCL+ 66:3 (2003) 494-496

Authors:

G Angloher, M Altmann, M Bruckmayer, C Bucci, S Cooper, C Cozzini, P Di Stefano, F von Feilitzsch, T Frank, D Hauff, T Jagemann, J Jochum, R Keeling, H Kraus, J Macallister, F Probst, Y Ramachers, J Schnagl, W Seidel, I Sergeyev, M Stark, L Stodolsky, H Wulandari

Abstract:

Results of the CRESST experiment at Gran Sasso using 262-g sapphire calorimeters with tungsten phase transition thermometers are presented. Calibration and analysis methods are described. Data taken in 2000 have been used to place limits on WIMP dark matter particles in the Galactic halo. The sapphire defectors are especially sensitive to low-mass WIMPs with spin-dependent interaction and improve on existing limits in this region. (C) 2003 MAIK "Nauka/Interperiodica".

Scattering of THz phonons

PHYSICA B 316 (2002) 589-591

Authors:

Abstract:

Using heat pulses, we studied the elastic scattering of THz phonons in sapphire and calcium tungstate, two materials of interest as absorbers in composite detectors of particles and photons. For sapphire, we modelled the power dependences of specularly reflected and bulk scattered phonons, whilst for calcium tungstate the transmitted diffusive signal was measured. In both materials, the measured rate was consistent with Rayleigh scattering by isotopes, of oxygen in Al2O3 and of tungsten in CaWO4. In addition, strongly non-linear effects were observed in CaWO4.
