The ArTeMiS cryostat in position at APEX

The ArTeMiS cryostat installed in the APEX telescope on the Chajnantor Plateau in northern Chile. ArTeMiS is a new wide-field submillimetre-wavelength camera that will be a major addition to APEX’s suite of instruments and further increase the depth and detail that can be observed. The new generation detector array of ArTeMIS acts more like a CCD camera than the previous generation of detectors. This will let wide-field maps of the sky be made faster and with many more pixels.
