The SIB264 multianode photomultiplier tube interface
board provides the mechanical and electrical connectivity between the Photonis XP85013 series 64 anode MCP-PMT and external signal processing electronics such as Vertilon’s PhotoniQ multichannel data acquisition systems. The XP85013 is mounted to the bottom side of the SIB264 through 128 socket pins that connect the MCP-PMT’s 64 anode signals 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 SIB264 to be
conveniently mounted directly into the user’s optical setup with the MCP-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 XP85013 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 MCP-PMT’s cathode is supplied directly from the PhotoniQ on a high voltage cable to a dedicated connector on the SIB264. This voltage is used by an onboard bias generator circuit to derive the required high voltages for the XP85013’s microchannel plate. For applications requiring timing pickoff from the XP85013, the SIB264 includes a two stage high speed preamplifier for the microchannel plate output and three types of pulse discriminators. The outputs from a leading edge, constant fraction, and zero slope discriminator respectively generate trigger signals based on a threshold, percentage of pulse height, and pulse peak. These outputs as well as the preamplifier output are available to the user for connection to the PhotoniQ or other external electronics. Several user adjustments are included for optimizing system gain and trigger thresholds for the discriminators. SIB264 multianode photomultiplier tube interface board 特點:
