As an alternative to aperture optics, the authors describe a microprobe based upon a radiographic microfocus x-ray tube and glass capillary optics. High intensities were obtained by placing the capillary very near the microfocal spot to maximize the acceptance angle. The total reflection of x-rays through the capillary reduced the 1/r{sup 2} losses associated with aperture optics. The beam characteristics and minimum detection limits of the latest version of the microprobe are presented along with examples of applications. 5 refs., 5 figs.
