Rubin M1M3 Dynamic performance : stability and actuation during operations
HyeYun Park, Petr Kubánek, Kshitija Kelkar +20
The Vera C. Rubin Observatory is preparing to commence the Legacy Survey of Space and Time with the fully integrated Simonyi Survey Telescope. To verify that the primary/tertiary (…
An overview of stray light findings and interpretation during on-sky commissioning of LSSTCam
Gabriele Rodeghiero, Alex Drlica-Wagner, Alessio Taranto +78
Wide-field telescopes are intrinsically difficult to shield from unwanted stray and scattered light, while the search to identify sources of contaminating light is frequently a cha…
Investigation and Mitigation of a Prominent Off-Axis Stray Light Path in Rubin Observatory Commissioning
Alex Drlica-Wagner, Alessio Taranto, Gabriele Rodeghiero +12
The "scratched tape" stray light feature is the most prominent and prevalent stray light artifact identified during the commissioning of the Vera C. Rubin Observatory. The scratche…
Mechanical Studies of an Additional Light Baffle for the LSST Camera
Hannah Mary Margaret Pollek, Gabriele Rodeghiero, John Andrew +11
Commissioning the NSF-DOE Vera C. Rubin Observatory consisted of engineering operation and on-sky data-taking, initially with the Commissioning Camera followed by the commissioning…
Determining stress-based bending mode limits for the Vera C. Rubin Observatory M1M3 active mirror system
Malhar Sonaniskar, Douglas Neill, Ellie Hileman +1
The Vera C. Rubin Observatory Simonyi Survey Telescope's primary-tertiary mirror (M1M3) is an actively supported, 8.4-m cast borosilicate optic controlled by 156 pneumatic actuator…
Modeling of the diffuse background produced by the Vera C. Rubin Observatory M2 baffle scattered light
Alessio Taranto, Gabriele Rodeghiero, Luca Rosignoli +58
The Vera C. Rubin Observatory, with its unprecedented field of view and fast focal ratio, will survey the entire sky every 3.5 nights. This unique capacity requires dealing with of…
