Reduction of the output ripple in X-ray detectors

摘要

In a multichannel X-ray detector based on epitaxial GaAs structures, a low-pass filter was used to reduce the ripple at the amplifier output. From the transient processes observed during the X-ray scanning, the optimum filter passband was determined. An X-ray source with a medium-frequency power-supply generator was used to estimate the image quality.
