CRESST in the Gran Sasso Tunnel

A building three stories high hosts the CRESST Experiment in the Gran Sasso Tunnel.





Schematic drawing of a CRESST detector module consisiting of a target crystal linked to a thermometer and a light absorber connected to a second thermometer. Both detectors are surrounded by a reflective and scintillating houseind



A typical transition curve

A typical transition curve. Since it is very steep, a small change in temperature results in a measurable change of resistance.

Different parts of a beaker module: Silicon beaker acting as light detector and CaWO4 target crystal.



 

Test cryostat container

The container housing the CRESST R&D cryostat.



Calcium tungstate crystals in UV

Calcium tungstate is a scintillator material. When the crystals are excited, here by ultraviolet light, they emit light themselves.





Opened CRESST-II detector module of the conventional design.





Detector carousel containing all detector modules.





Detector Mounting at Gran Sasso. Near the detectors, all work has to be done under clean room conditions.
