Supply and service agreement for detailed design, fabrication, verification, transport and installation of the radial collimator. The radial collimator shall be installed on a support structure that will also be used as a lift.
The radial collimator shall be installed in front of the detectors with a coverage of approximately 165°. The radial collimator shall oscillate during operation and that should be integrated in the design.
The support & lift structure will be included in this tender as an option, but the final design of the radial collimator shall not prevent future integration with the support & lift structure.
Design requirements;
The radial collimator shall have a coverage of approximately 165° with a an oscillation of +/- 2 mm.
Alignment specification (x, y, z) < 1 mm. Rotational specification of 0.22°.
Low resolution (1°) collimator with the following dimensions;
Inner radius: 545 mm
Length: 790 mm
Sample position to detector: Fixed at 800 mm
Collimator entrance dimension: 9.5 mm
Collimator exit dimension: 13.9 mm
The radial collimator and the oscillation system must comply with the collimator support structure (interface description delivered by ESS)
Handling & Maintenance features
All materials shall be non-magnetic.
Foil coating; Gd Oxide or Boron-10 Carbide
Optional addons;
Detailed design, fabrication, verification, transport and installation of the “Collimator Support & Lift”
The “Collimator Support & Lift” shall be a motorized lift that shall be used to support and position the radial collimator at a specific height The height is approximately 2 meters from ground level.
The specification and the conceptual design of the “Collimator Support & Lift” is not yet defined.
Expected delivery: June 2026
