The short light pulses from the photoelectric injector drive laser in both the visible ((lambda)=496 nm, (Delta)t(approximately)1.5 ps (FWHM)), and the ultraviolet ((lambda)=248 nm, (Delta)t(approximately)5 ps (FWHM)) were used. Both a UV-visible S20 photocathode streak tube and a UV-to-x-ray Au photocathode streak tube were tested. Calibration data with an etalon were also obtained. A sample of dual-sweep streak data using optical synchrotron radiation on the APS injector synchrotron is also presented. 收起
