03 Oct 2014 The SIB464 sensor interface board allows for a SensL ArrayB-60035-64P 8 x 8 silicon photomultiplier (SiPM) array to easily interface to a Vertilon PhotoniQ multichannel data acquisition system. The SiPM is inserted into the bottom side of the printed circuit board where its anode output signals are routed directly to two sensor interface board (SIB) connectors. Each connector mates to a micro-coaxial cable assembly that connects 32 device outputs to the PhotoniQ. Bias to SiPM array is provided by an on-board adjustable high voltage bias supply. A special current-sense output on the supply is available that represents the AC charge signal produced by the SiPM array. This signal is fed into a user-programmable leading edge discriminator that generates a trigger signal when an event exceeding a preset energy threshold is detected on the ArrayB-60035-64P device. The trigger output is typically connected to the trigger input on the PhotoniQ data acquisition system where it is used to initiate the collection of the energy signals from the SiPM array connected to the DAQ system’s inputs. |
