Product Overview
The SIB71256 multianode photomultiplier tube interface board provides the mechanical and electrical connectivity
between the Hamamatsu H13700 256 anode PMT and external signal processing electronics such as Vertilon’s PhotoniQ
multichannel data acquisition systems. The MAPMT is mounted to the bottom side of the SIB71256 through a pair of
socket connectors that route the PMT’s 256 anode signals and last dynode output to the board. The high voltage bias to
the PMT is supplied separately on its own cable and thus never reaches the SIB71256. The anode signals are routed to
an on-board resistive anger logic circuit that generates four anger signal outputs. Each output is fed to an inverting
amplifier and made available to the user on an SMB connector. Event position and energy information can be determined
by connecting the four anger signal outputs to customer-supplied electronics. For timing applications utilizing the last
dynode output of the PMT, the SIB71256 includes a high speed non-inverting preamplifier whose output is also available
on an SMB connector. The polarity of the preamplifiers is such that the four anger and last dynode outputs produce all
positive going signals.
The various functions on the SIB71256 are described in greater detail on the following pages. When necessary, refer to
the functional block diagram shown in Figure 1 below.

Typical Setup
A typical setup using a SIB71256 is shown below. The Hamamatsu H13700 MAPMT is mounted to the SIB71256 and
positioned to detect incoming light from a scintillator crystal or optical assembly. The four anger logic outputs from the
SIB71256 connect to four inputs on a PhotoniQ IQSP418 / IQSP518 multichannel PMT data acquisition system. Digitized
output data from the PhotoniQ is sent through a USB 2.0 connection to a PC for display, logging, or real time processing.
The amplified last dynode signal from the SIB71256 connects to an external discriminator that generates a trigger to the
PhotoniQ. A high voltage bias of up to negative 1200 volts is sent directly to the PMT from an SHV connector located on
the rear of the PhotoniQ. Note that the high voltage output is an optional configuration on the IQSP418 / IQSP518.

Photomultiplier Tube Anode Circuit
The 256 anode signals (P1 – P256) from the H13700 MAPMT are routed directly on the SIB71256 to the resistive anger
logic circuit shown in the figure below. Each anger signal is amplified by high speed inverting preamplifiers and output on
the SMB connectors on the four corners of the printed circuit board. The gain of the preamplifiers can be configured by
the user to one of two settings using miniature rotary switches on the PCB. The anger signals can interface to a charge
integrating data acquisition system like a Vertilon PhotoniQ IQSP418 or IQSP518 to extract energy and position
information.

Anger Logic
Position information is obtained from the SIB71256 anger logic circuit using the formulas below to determine the X and Y
coordinates.
Xpos= (V1+ V16 – V241 – V256) / (V1+ V16 + V241 + V256)
Ypos= (V1+ V241 – V16 – V256) / (V1+ V16 + V241 + V256)
An actual plot of the position signal using the above formulas is created by successively injecting a negative DC current
into each anode and collecting the charge data using a Vertilon PhotoniQ IQSP418 charge integrating data acquisition
system. This is shown Figure 4 below.
Figure 4: Position Signal Plot
Figure 5 shows the typical response from an anode preamplifier (in the high gain setting) when a charge pulse is injected
into one of the four corner anodes (P1, P16, P241, P256).

Last Dynode Output
The last dynode of the H13700 is directly connected on the SIB71256 to a non-inverting preamplifier whose output is
available on an SMB connector. A miniature rotary switch allows the user to select between one of two gain settings. The
last dynode output is typically used with an external discriminator for generating a trigger signal to data acquisition
electronics or a time-to-digital converter (TDC) for determining time of arrival or coincidence detection. The figure below
shows the last dynode preamplifier response (in the high gain setting) to a voltage signal injected into the DY10 location
on the SIB71256.
Figure 6: Dynode Preamplifier Response
Gain Switches
The SIB71256 utilizes five miniature two-position switches to adjust the gain of the four anode preamplifiers and last
dynode preamplifier. The preamplifier gain can be set to either a low or high setting by using the included adjustment tool
to rotate the switches’ rotor. It is recommended that the user avoid turning the switches beyond the stops at the end of
each position. The figure below indicates the switch position for each gain.
