Impressive machining of the second (of 5) top part of the Liquid Nitrogen vessel for #ETpathfinder at @nikhef.bsky.social

Volume of this vessel will be 45L and will be filled with 25L liquid Nitrogen (N2) to cool the cryogenic shields in the four mirrors towers

One month ago the Beam Splitter (BS) tower was installed in the bottom part of the vacuum vessel at #ETpathfinder. Now that all filters have been tuned, the vacuum vessel can be closed.
