TL;DR

The paper reports on the progress of the CRESST dark matter search, highlighting new detector developments that improve background discrimination and enhance sensitivity to WIMP detection.

Contribution

Introduction of a new simultaneous measurement method for phonons and scintillation light, significantly reducing background and increasing detection sensitivity in larger detectors.

Findings

Enhanced discrimination between signal and background

Improved WIMP detection sensitivity

Abstract

We present the current status of CRESST(Cryogenic Rare Event Search using Superconducting Thermometers) project and new results concerning the development of new detectors based on the simultaneous measurement of phonons and scintillation light. A significant reduction in the background rate could recently be achieved. With our newly developed method for the simultaneous measurement of scintillation light, strong background discrimination is possible also in larger detectors, resulting in a substantial increase in WIMP detection sensitivity.
