Description
Previous work on the FGLD (Field Gradient Lattice Detector) involved reading
out 50 strips from the detector using the GP5 chip: a 128-channel charge
sensitive preamplifier with integrated individually programmable trigger. The
work showed that the GP5 was suitable as a front-end electronics, but
demostrated the need to protect the inputs from discharges inherent in the
detector. To that end, the 128-channel diode protection chip developed for
the GEM TOTEM experiment has been successfully adapted to the GP5 and
shown to make the GP5 resilient to destruction under harsh discharging.
Armed with this robust front-end electronics and the FGLD technology, the
group has developed a prototype imaging system capable of producing
images relevant for medical and industrial applications. A discussion of the
system’s parameters and performance will be presented, along with some
high-resolution images made with a dental X-ray machine.
