A solft X-ray beam-position monitor based on a CVD diamond photodetector is presented, for use on low-energy monochromatic beamlines. It allows monitoring of beam instabilities during experiments towards simultaneous compensation.

At 11.0 GPa the diamond-type structure changes in the high-pressure phase with an increse in coordination numbers, and prolonged bonding distances make the magnitudes of σ(2) larger.

A fast (∼12 ms) shutter for UHV beamlines is described. In the closed position the beam is blocked by an electrically isolated aluminium piece. The total yield photocurrent in this situation can be used to monitor the beam intensity.
