Abstract

The coudé lab is one of the central components of the Coudé Environmental Systems (CES) at the Daniel K. Inouye Solar Telescope (DKIST). The scientific instruments for DKIST are located on benches inside the coudé lab. The light path from the telescope to the coudé lab goes from ambient to conditioned space, therefore, in order to minimize local seeing or wave front distortion, the CES was designed. The CES is composed of the Air Knife and equipment that condition the coudé lab to the desired cleanliness, temperature, and humidity design parameters. The Air Knife uses an air curtain to divide the external ambient space from the conditioned coudé lab through a series of fan operated and filtered ducted assemblies. The coudé lab is conditioned using filtered air handling units, makeup air handling units, a HEPA filter plenum ceiling, floor dampers, and humidifiers. The installed CES equipment shall be tested and results shall be presented to determine whether the design parameters
