Details of the Chambers:
· The provider will be responsible for manufacturing two complete chambers, each consisting of a chamber body and three blank flanges.
· The chamber body is a welded structure with approximate dimensions of 500–600 mm per side. The material specified for the body is AISI 316L, while the flanges welded to the body are made of AISI 316LN ESR.
· The primary flanges to be welded on the body include 2x DN300CF and 1x DN250CF. Precise positioning and orientation (well below 0.1 mm tolerance) of these flanges are critical.
Additional Features:
· High-precision machining and high-quality surface finishing are required.
· Electrical feedthroughs of various dimensions need to be welded.
· One flange will require precision welding of additional pipes and vacuum ports, with exact positioning and orientation.
· All components must be UHV-compatible and adhere to the XFEL "UHV Guidelines for X-Ray Beam Transport Systems" (see: https://docs.xfel.eu/alfresco/d/a/workspace/SpacesStore/75911c8c-6b91-4f8a-ba30-c0bc706c29cc/TN-2011-001-04_UHV_WP73.pdf ).
