The SIB064B multianode photomultiplier tube interface board provides the mechanical and electrical connectivity between Hamamatsu 64 channel MAPMTs and external signal processing electronics such as Vertilon’s PhotoniQ multichannel data acquisition systems. The PMT is mounted to the bottom side of the SIB064B through 148 socket pins that connect the device’s 64 anode signals, high voltage input, and last dynode output to the board. The anode signals are routed to two connectors located on the top of the board that each connect to a specialized high density coaxial cable assembly. This arrangement allows the SIB064B to be conveniently mounted directly into the user’s optical setup with the PMT facing outward from the bottom of the board and the sensor interface board (SIB) cables exiting from the top. The SIB cables carry the 64 anodes from the PMT to the PhotoniQ where the charge from each is separately integrated, digitized, and sent to a PC for display or further signal processing. The negative high voltage bias to the PMT’s cathode is supplied directly from the PhotoniQ on a high voltage cable to a dedicated connector on the SIB064B. For applications utilizing the last dynode output of the MAPMT, the SIB064B includes a two stage high speed preamplifier whose output is available on an SMB connector. When specialized timing and triggering are required, this output can be connected to a separate external discriminator and triggering electronics. Alternatively, for more general purpose applications when the trigger requirements are not as stringent, one of the two on-board discriminators can be used. A leading edge and zero slope discriminator — which respectively generate trigger signals based on a threshold and pulse peak — are available to the user. Several adjustments are included for optimizing preamp gain, discriminator gain, and discriminator energy thresholds. The full functionality and operation of the SIB064B is conveniently controlled through the PhotoniQ’s graphical user interface. Intelligent software in the PhotoniQ constantly monitors the status of its SIB connectors to determine the type of sensor interface board attached to them. Once recognized, a dialog box specific to the recognized SIB is made available in the GUI through which the user has complete control over its operation.
