Many improvements to the storage ring and beamlines were performed during the fall shutdown at the CLS. At BioXAS, CLS engineers and technicians installed a new air conditioning system to keep the optical elements, detectors, and electronics operating within their optimal temperature ranges. This will increase beam stability and improve the detector signal to noise ratio. The work will be completed for the start of cycle 33 in January 2021. Shown are pictures of the AC installation.
