Abstract
Abstract
The Medipix4 chip is the latest member in the
Medipix/Timepix family of hybrid pixel detector chips aimed at
high-rate spectroscopic X-ray imaging using high-Z materials. It can
be tiled on all 4 sides making it ideal for constructing large-area
detectors with minimal dead area. The chip is designed to read out a
sensor of 320 × 320 pixels with dimensions of
75 μm× 75 μm or 160 × 160 pixels
with dimensions of 150 μm× 150 μm. The
readout architecture features energy binning of the single photons,
which includes charge sharing correction for hits with energy spread
over adjacent pixels. This paper presents the specifications,
architecture, and circuit implementation of the chip, along with the
first electrical measurements.
