[ad_1] THE DOCUMENT IN BRIEF • Intense, ultrashort X-ray pulses generated in facilities known as X-ray free electron lasers (XFELs) have been used to investigate light-induced structural changes in proteins. • Light-sensitive proteins typically absorb an optical or ultraviolet photon in natural environments, but could absorb more of the intense “pump” lasers used to induce … Read more

[ad_1] The laser signal collected by the camera is then transmitted through an optical fiber that feeds a cryogenically cooled semiconductor nanowire single-photon detector. Designed and built by JPL Microdevice Laboratorythe detector is identical for the one used at Caltech’s Palomar Observatory, San Diego County, California, which acts as DSOC’s downlink ground station. “It’s a … Read more
