Abstract

An electrical response of a diffracting diamond (111) crystal was studied in a single electrode configuration where the electrode was deposited on a small portion of the crystal entrance surface. The experiment was performed in ambient air using an x-ray beam after a Si (111) double-crystal monochromator with the diamond crystal set in the Bragg diffraction condition. It was found that the electric current as a function of the Bragg angle exhibits behavior characteristic of secondary yield curves (e.g.,¹). It is proposed to utilize this effect to monitor the intensity of the Bragg reflected x-ray beam. Such non-invasive monitoring does not rely on the use of stand-alone radiation monitors (e.g., ionization chambers) and is expected to facilitate x-ray optics alignment procedures. As an attempt to improve signal-to-noise ratio by containing the electric field in the optical element an electric response of a high-resistivity silicon crystal was studied in a two-electrode configuration. Preliminary results are reported.
