AI Contract Overview

This contract involves modifications to the NIST SST1 Beamline at NSLS II in Brookhaven, New York, to integrate a new NEXAFS experimental station. The scope of work includes removing the M5 mirror to improve optical efficiency and floor space, relocating the DM8 diagnostic module to a dedicated base frame, and verifying that DM8 imaging capabilities are compatible with M4C and M4D dithered beams. Additionally, the project requires replacing the existing NEXAFS station with a design based on the SST-2 HAXPES chamber and installing a new support stand for a 10,000-element detector. Critical technical requirements for these upgrades include maintaining ultra-high vacuum levels throughout the beamline and ensuring that the downstream beam path remains unperturbed during normal operation. All new components must be installed with a precision tolerance within a few microns. This effort is managed by the Department of Commerce under the agency for Laboratory Programs.

Full Description

1) Removal of current M5 mirror to increase overall beamline optical efficiency (one less reflection) and increase useable beamline floor space, and simplifying beamline optics.2) Reconfigure and relocate current DM8 diagnostic module on its own dedicated base frame.3) Confirm that DM8 Io mesh and screens can image M4C and M4D dithered beams.4) Replace current NEXAFS experimental station with a new design based upon a chamber similar to the Hard X-ray Photoemission Spectroscopy (HAXPES) station on SST-2.5) Introduce a new Support Stand for the 10,000-element detector, compatible with the existing soft x-ray optical path in conjunction with the new NEXAFS experimental chamber.These changes need to occur while ensuring that: all new components fit perfectly to atolerance within a few microns; the downstream beam path is unperturbed in normaloperation; the ultra high vacuum levels are maintained throughout the beamline.
