Vera C. Rubin Observatory LSST Camera Focal Plane Build 032

Testing the process of installing RTMs into the cryostat using a mechanical RTM and prototype cryostat assembly. These mechanical prototypes have all of the same features and most of the same tolerances as the real RTMs and cryostat assembly, but use metallic components in place of the CeSic (carbon fiber reinforced silicon carbide) and non-functional CCD sensors.
