Design and prototyping of SiPM electronics (view source)

The pages listed here describe the work in electronics undertaken to support Silicon Photomultiplier (SiPM) based readout of the Tagger Microscope for JLab Hall-D and the GlueX experiment in particular. The working design concept for the Tagger's readout involves an array of PCB boards with SiPM's and their amplifier, summing circuits etc. suspended in a light-tight box out of the plane of incoming electrons. Each of these "analog boards" are connected across a light-sealing bus board to a "digital board". The latter principally contains bias voltage control circuitry and an architecture that allows ethernet-based communication with a controlling PC, which will monitors the Tagger and adjust individual channel bias. An added advantage of this two-tier design is the ease with which the tagger can be wired without introducing light leaks: the SiPM signals are passed into a chamber more tolerant of ambient light. (The coaxial then take the signals from the digital boards.)
