Description
The Compact X-ray Light Source (CXLS) at Arizona State University is a compact inverse-Compton-scattering (ICS) facility designed to provide femtosecond hard X-rays in a university laboratory environment. CXLS has entered commissioning and early-science operation, demonstrating stable operation of a 9.3 GHz X-band accelerator, synchronized picosecond laser systems, and femtosecond hard X-ray generation at 1 kHz repetition rate. Initial operation has produced hard X-rays near 9.25 keV with sub-ps duration, micron-scale source size, and timing jitter below 100 fs. Early experiments have commissioned the multimodal X-ray endstation for time-resolved diffraction and spectroscopy, including the first protein crystallography results obtained at CXLS.
This talk will summarize commissioning performance of the accelerator, RF, laser, and X-ray systems, including recent results from structural biology and quantum materials experiments. We will also discuss construction of the Compact X-ray Free-Electron Laser (CXFEL) which is underway. CXFEL extends the compact ICS architecture toward fully coherent soft X-ray pulses with femtosecond-to-attosecond duration. We’ll touch on the advanced beam manipulation methods, including nanopatterned electron beams and emittance-exchange concepts, for achieving coherent X-ray generation as well as future applications in structural biology, ultrafast chemistry, quantum materials, and multipulse/multicolor schemes.
