Abstract
We investigated silicon-based avalanche photodiodes (APDs) as X-ray de tectors in terms of their linearity, maximum counting rates, and dynam ic range with 8.4 keV synchrotron radiation. Measurements resulted in counting rates that extend from the APD's noise level of 10(-2) Hz to saturation counting rates in excess of 10(8) Hz. In addition, by monit oring the APD's noise level and photon counting efficiency between syn chrotron bursts, we demonstrate nine orders of magnitude dynamic range .
