Description of the Contract
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.  Within the facility (see an overview in Figure 2.1), high precision optical systems will be installed, together with their vibration isolation units, inside an ultra-high vacuum vessel (UHV) which provides the environment for the R&D activities. A more detailed description of the ETpathfinder project can be found in: https://www.etpathfinder.eu/.

A CAD view of the Cryogenic Shield Assembly, consisting of primarily Aluminum (left: full model, right: cross-section) can be found in Figure 1. For reference, the outer dimensions of the "box" are: 1390x690x1280mm, not including the cylindrical portion at the bottom. In total 5 of such assemblies are to be manufactured. Further details are given in the bill of materials (BOM) and the CAD drawings, see the program of requirements section.
