New Sensor Interface Board Supports Hamamatsu 64 Channel MAPMT
Westford, MA (PRWEB) July 14, 2008 - Vertilon Corporation ( http://www.vertilon.com ), a leader in high performance multichannel data acquisitionsystems for optical sensors, announced today that it has launchedthe SIB164 sensor interface board for the Hamamatsu H7546Bsixty-four anode photomultiplier tube. The SIB164 provides themechanical and electrical interface between the H7546B and a 64channel data acquisition system like Vertilon's PhotoniQ IQSP482 orIQSP582. Charge signals from high speed events such as thoseproduced in PET or gamma cameras are detected by the PMT mounted onthe SIB164 and sent over specialized cables to the data acquisitionsystem. When used with an IQSP582 PhotoniQ system, the SIB164achieves single photon sensitivity at event rates exceeding 200,000events per second. The SIB164's compact and standardized designallows the typical user to easily mount the Hamamatsu H7546B to itand collect data from the PhotoniQ -- no custom electronics,specialized equipment, or additional software is required. Similarin function to Vertilon's SIB064 for the Hamamatsu H8500D, theSIB164 has a last dynode preamplifier and three types of on-boardpulse discriminators. In many applications the last dynode from thePMT offers a convenient means for detecting particle orscintillation events since it is effectively a shared connectionbetween all anodes in a multianode photomultiplier tube. A pulsefrom the last dynode is coincident with the output from the PMTanodes and therefore can be used to initiate the collection of thecharge signals by a data acquisition system. The discriminatorsthat follow the preamp convert the last dynode charge signals intodigital pulses that are used to trigger the PhotoniQ or, ifnecessary, other equipment. The SIB164 also includes the interfaceto the H7546B high voltage cathode bias which can be convenientlysupplied by the PhotoniQ. "The SIB164 represents the latestaddition to our growing line of products for multianodephotomultiplier tubes, avalanche photodiodes, and siliconphotomultipliers" said Vincent Palermo, President and Founderof Vertilon. "With each new product Vertilon has shown that itis at the forefront of the industry for high performancemultichannel data acquisition systems." Vertilon says theSIB164 is in production and available today. The company alsomanufactures sensor interface boards for other commonly availablemultianode PMTs and avalanche photodiode arrays like Hamamatsu'sH8711, H7260, H8500D, and R5900U-L16, as well as for PacificSilicon Sensors' AD-LA-16-9-DIL18 16 element linear avalanchephotodiode array. Target applications for Vertilon's productsinclude PET, single photon emission computed tomography (SPECT),high energy particle physics, gamma cameras, flow cytometry,confocal microscopy, small animal imaging, and radiationmonitoring.
