Reason for the Tender Procedure
Maastricht University as the lead-partner in the ETpathfinder project will host a facility aimed at the development and tests of extremely sensitive optical interferometers like those used in gravitational wave detectors. The primary goal is to improve the sensitivity to the level required by future generations of gravitational wave detectors. ETpathfinder will be an international center for research into high-precision measurement techniques, vibration isolation, measurement and control software,
cryogenics and (quantum) optics in the context of next-generation gravitational-wave infrastructures.

The facility will include an ultra-high vacuum vessel to be installed in a large cleanroom at Maastricht University which provides the environment for the future R&D activities.
The ultra-high vacuum vessel, connected with large bellows, is intended to achieve an Ultra High Vacuum (UHV).

A more detailed description of the ETpathfinder project can be found in:
