Liquid nitrogen pre-cooling system for ELT instruments utilizing additively manufactured heat exchangers, integrated temperature and liquid level control
Anastasios Aretos, Younes Chahid, Lee Chapman +5
Using liquid Nitrogen as the cryogenic fluid for pre-cooling purposes is almost ubiquitous across modern observatories. That method tends to be inefficient since it relies on the e…
Laser Remelting for Reduced Porosity on Additively Manufactured Aluminium Mirrors
Joshua West, Valentina Oyarzun, Marcell Westsik +17
Additively manufactured (AM) AlSi10Mg mirrors are fabricated through laser powder bed fusion (LPBF), allowing the use of complex geometries such as lattices and organic structures…
Additive manufacturing in aluminium of a primary mirror for a CubeSat application: manufacture, testing and evaluation
Ilhan Aziz, Younes Chahid, Jennifer Keogh +16
Additive manufacturing (AM; 3D Printing), a process which creates a part layer-by-layer, has the potential to improve upon conventional lightweight mirror manufacturing techniques,…
Design, manufacture and metrology of additively manufactured, metal and ceramic lightweight circular mirror prototypes
Greg Lister, Rhys Tuck, Younes Chahid +9
Spaced-based mirrors are a developing use-case for Additive Manufacturing (AM), the process that builds a part layer-by-layer. The increased geometric freedom results in novel and…
