The system consists of a high-vacuum chamber, multi-ported, equipped with deuterium and xenon sources for accelerated ageing of coatings under vacuum. The specimen to be irradiated is mounted on a temperature-controlled platen, which, in turn is mounted on a XYZ J manipulator. Provision is made for the measurement of emissivity and absorptance without breaking vacuum and at the operating temperature.

The chamber is fitted with a magnetically levitated turbo molecular pump and scroll backing pump meaning the system is oil free.
