WESTFORD, Mass., Dec. 19, 2011 — Vertilon Corp. has launched the SIB416 for testing and evaluating the Hamamatsu S11064 multipixel photon counter. It is designed to give researchers and developers a quick and easy way to evaluate the S11064 low-light-level sensor.
Multipixel photon counters offer a lower cost, solid-state alternative to photomultiplier tubes in select applications. The S11064 is used in positron emission tomography, single-photon-emission computed tomography, gamma cameras and radiation detection.
Designed for direct interface to Vertilon’s PhotoniQ charge-integrating DAQ systems, the SIB416 includes all of the electrical and mechanical hardware to support data acquisition from up to 64 input channels from up to four Hamamatsu multipixel photon counters. The S11064 devices mount to the SIB416, and their cathode signals are routed to connectors that interface to charge-integrating preamplifiers in the PhotoniQ DAQ.
A special current-sense output from the photon counter anodes is used to represent the combined charge signal measured from all SiPM devices in the arrays. This signal is fed to a user-programmable leading edge discriminator that generates a trigger signal when an event exceeding a preset energy threshold is detected on any of the S11064s.
The PhotoniQ graphical user interface provides a convenient way to configure all adjustable parameters on the SIB416.
