The SIB416 sensor interface board allows up to four Hamamatsu S11064 multipixel photon counter (MPPC) devices to easily interface to a Vertilon PhotoniQ multichannel data acquisition system. The devices are inserted into receptacle
pins where their cathode output signals are routed to connectors that connect the device outputs to the PhotoniQ. Bias to MPPC arrays is provided on a high voltage cable by the PhotoniQ where it can be enabled and configured through the PhotoniQ graphical user interface. A special current-sense output from the bias interface circuitry is sent to a variable gain preamplifier to represent the total charge signal measured by all four MPPC arrays. This signal is fed into a userprogrammable threshold leading edge discriminator that generates a trigger signal when an event exceeding a particular energy threshold is detected on any of the S11064 devices. The trigger output is typically connected to the trigger input on the PhotoniQ data acquisition system. Alternatively, the trigger output can be sent to other external hardware that could perform coincidence detection or precise time-to-digital conversion. The full functionality and operation of the SIB416 is conveniently controlled through the PhotoniQ’s graphical user interface. SIB416 sensor interface board 特點：
