The SIB164B-1018 multianode photomultiplier tube interface board provides
the mechanical and electrical connectivity between the Hamamatsu H7546B and H12428 64 anode PMTs and external signal processing electronics such as Vertilon’s PhotoniQ multichannel data acquisition systems. The H7546B or H12428 is mounted to the bottom side of the SIB164B-1018 through 66 socket pins that connect the PMT’s 64 anode signals, last dynode output, and high voltage input to the board. The high voltage bias to the MAPMT is supplied through the SIB164B-1018 on a specialized cable from the PhotoniQ. The anode signals are routed to an on-board resistive anger logic circuit that generates four anger signal outputs. These outputs connect using four coaxial cables to Vertilon’s PhotoniQ IQSP418 or IQSP518 multichannel data acquisition system where the charge from each is separately integrated, digitized, and sent to a PC for display or further signal processing. For applications utilizing the last dynode output of the H7546B or H12428, the SIB164B-1018 includes a two stage high speed preamplifier whose output is available on an SMB connector. One of two on-board discriminators can be used with the last dynode signal to generate a trigger to the data acquisition system or other external electronics. The outputs from a leading edge and zero slope discriminator — which respectively generate trigger signals based on threshold and pulse peak — are available on SMB connectors. Several user adjustments are included for optimizing system gain and trigger thresholds for the discriminators. SIB164B-1018 multianode photomultiplier tube interface board 特點：
