Abstract

A VLSI readout chip for a solid-state hybrid pixel detector for two-dimensional real-time imaging is part of a project with the goal to construct a large-area digital detector with good efficiency for X-rays in the energy range 20 - 70 keV. A new circuit concept with integrated analog counters in each cell makes the detector suitable for high-intensity dynamic imaging. The aim is to acquire 12-bit images with a speed of up to 100 frames per second. The detector concept also includes single-photon counting and an adjustable threshold. The size of the pixel is a trade-off between spatial resolution and amount of implemented logic, and is chosen to 270 micrometer X 270 micrometer. A 8 X 8-channel prototype readout chip, (ANGIE), with a pixel size of 250 micrometer X 250 micrometer, has been fabricated and tested. The results from functional tests are presented.
