UKATC
The UK Astronomy Technology Centre is the national centre for astronomical technology. We design and build instruments for many of the world's major telescopes. We also project-manage UK and international collaborations. Our scientists carry out observational and theoretical research into fundamental questions such as the origins of planets and of galaxies.

- CAD files from "Lightweighting large optomechanical structures in astronomy instrumentation utilising generative design and additive manufacturing"(2023-07-06) Atkins, Carolyn; Wells, James T.; Westsik, Marcell; Chahid, Younes; Mcleod, Alastair; Bissell, Lawrence; Kotlewski, Richard; McPhee, Scott; Orr, Jonathan; Pimentel, Misael; Cochrane, William; Breen, CiaránFiles contain .step files for the topology-optimised design and the varied wall thickness design. These designs are detailed in the paper submitted to SPIE Optomechanical Engineering 2023 titled "Lightweighting large optomechanical structures in astronomy instrumentation utilising generative design and additive manufacturing"
- Scanning electron microscopy images and energy dispersive X-ray spectroscopy of inclusions within AlSi10Mg mirrors created using additive manufacturing(2025-10) Atkins, Carolyn; Tammas-Williams, Samuel; Laidlaw, Fraser H. J.; Westwood, Dominic; Aziz, Ilhan; Chahid, Younes; Snell, Robert M.; McPhee, Scott; Cowan, JasonThe data provided herein describes the evaluation of inclusions within the surfaces of six aluminium mirrors created using additive manufacturing in the alloy AlSi10Mg. The inclusions are frequently observed to cause scratches on the mirror surface and by identification, routes for mitigation can be provided. The inclusions were evaluated using scanning electron microscopy and energy dispersive X-ray spectroscopy and subsequently were observed to be either aluminium oxides or contaminating metal alloys. The mirrors utilised different additive manufacturing machines with different operation environments, which allow the data to inform on routes where contamination has occurred. The data are organised by sample (mirror) number and the evaluated inclusion, with individual files describing topography and spectroscopy. The mirrors were approx. 50 mm in diameter and between 5 and 10 mm in height. The equipment used was a Zeiss Crossbeam 550 FIB-SEM located at the University of Edinburgh. Five detectors on the FIB-SEM were used in data collection: InLens, SESI, ESD, BSD4 and EDS.
