    The shell of the Large Aperture Telescope Receiver (LATR) arrived to Penn’s campus and was installed in the Devlin High Bay in the summer of 2019. Since then, researchers have been addressing key engineering and technical challenges, which range from holding temperatures at very precise stages, maintaining optical alignment, limiting temperature gradients, and minimizing the time it takes to move between temperatures.
