Paper Abstract

A system has been designed for concentration of an intense parallel beam of X-rays from a synchrotron. The system has two stages. The first stage consists of an array of tapered capillaries which decrease the beam cross section from 2 X 2 mm to about .05 mm and increase the beam divergence to near the critical angle. The second stage has a special asymmetric shape which decreases the beam cross section to 0.001 mm (1 micrometer) and increases the beam divergence to about 10 degrees. Although the optics have been optimized for 10 Kev X-rays, they should give substantial benefit over a range of X-ray energies from 5 - 20 Kev. The intensity gain is calculated to be between 5 X 103 and 105 depending on the transmission losses. The design parameters and the current experience with transmission measurements on prototype components will be reviewed. Questions relating to beam heating and radiation damage will also be discussed.
