Ts. Toellner et al., AVALANCHE PHOTODIODES AS LARGE DYNAMIC-RANGE DETECTORS FOR SYNCHROTRON-RADIATION, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 350(3), 1994, pp. 595-600
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
.
