Two new x-ray source systems are now on line at our facility. Each provides an {ital e}-beam to 25 kV. Targets are interchangeable between machines, and four x-ray detectors may be used simultaneously with a target. The gridded {ital e}-gun of the RACEHORSE system gives a 0.5--1.0-cm pulsable spot on target. The nongridded {ital e}-gun of the SCORPION system provides a 0.3-mm or smaller dc microspot on target. RACEHORSE is being used to study and characterize type-II diamond photoconductors for use in diagnosing plasmas, while SCORPION is being used to develop a slitless spectrograph using photographic film. Source design details and some RACEHORSE results are presented.
