Abstract
The Atacama Large Aperture Submillimeter Telescope (AtLAST) aims to be the
premier next generation large diameter (50 meter) single dish observatory
capable of observations across the millimeter/submillimeter spectrum, from
30~GHz to 1~THz. AtLAST will be sited in Chile at approximately 5100 meters
above sea level, high in the Atacama Desert near Llano de Chajnantor. The novel
rocking-chair telescope design allows for a unprecedentedly wide field of view
(FoV) of 1-2$^\circ$ diameter, a large receiver cabin housing six major
instruments, and high structural stability during fast scanning operations (up
to $3^\circ$ per second in azimuth). Here we describe the current status
of, and expected outcomes for, the antenna design study, which will be
completed in 2024.
