Typical Dual Sensor Setup
The Broadcom AFBR-S4N44P163 4 x 4 SiPM arrays are mounted to the SIB916s which are positioned in an optical
assembly to detect incoming radiation. The SIB cables from each SIB916 connect to a Vertilon SIB1632 where the 16
outputs from each SiPM array are combined into one SIB cable (SBC090) that connects to a PhotoniQ IQSP480 or
IQSP580 multichannel data acquisition system. The discriminator output from one SIB916 is fed to the coincidence
detector input on the other SIB916 so that a trigger to the PhotoniQ is produced whenever a near-simultaneous radiation
event is detected on both SiPM arrays. The energy level threshold for the radiation event is set by the user through the
PhotoniQ graphical user interface. Charge signals from the 32 cathodes from the two AFBR-S4N44P163 devices are
acquired by the PhotoniQ for each coincidence trigger produced by the SIB916. Digitized output data from the PhotoniQ
is sent through a USB 2.0 connection to a PC for display, logging, or real time processing. In the figure below, the
PhotoniQ GUI is set to display a dual 4 x 4 image of the energy levels for each event captured.

AFBR-S4N44P163 Detector Mounting
The SIB916 supports the Broadcom AFBR-S4N44P163 4 x 4 silicon photomultiplier array. This particular model of the
device is mounted to the bottom of the sensor interface board. The customer can reflow solder the SiPM array to the
SIB916 or Vertilon can perform this service. The SiPM device attached to a SIB916 is shown below.
