IDT have designed and implemented a full upgrade to the existing ‘Daresbury’ DCM on GSECARS Sector 13 at the APS. This was part of an upgrade of the ID beamline to a 1mrad canted undulator geometry.

The original DCM has been in operation for 15 years and the mechanical Bragg axle & vacuum vessel were re-used.

The upgraded DCM featured a new ultra-stable crystal cage designed for the 1mrad canted undulator beam geometry with indirect cryo-cooled Si(111) & Si(311) crystals, a new in-vacuum Bragg encoder using the latest Renishaw technology, and a new high-stability natural granite base block.

IDT have designed and implemented a full upgrade to the existing ‘Daresbury’ DCM on the DUBBLE CRG at the ESRF.

The original DCM featured a single Si(111) crystal set and has been in operation for 15 years.

The upgraded DCM features a new ultra-stable crystal cage Si(111) & Si(311) crystal sets with a novel direct water-cooling   scheme optimised for the beam footprint, a new in-vacuum Bragg encoder using the latest Renishaw technology, and a new high-stability natural granite base block.

The existing goniometer and DC servo drive train, crystal cage extraction mechanism, and vacuum vessel & ion pump were reused.
