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.

Schematic drawing of the module design of CRESST-II Phase 2 where the crystal is held by CaWO4 sticks.

Exemplary module of the stick design.

Schematic drawing of the beaker module design.

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.
