Counting photons

Hamamatsu Photonics introduces a new member of the MPPC family of solid state photon counting detectors. The new S11064 series builds on the success of Hamamatsus single element MPPC detectors and provides a 16 channel array of 3mm by 3mm detectors giving a total effective area of 144 mm2. The new device utilizes a Geiger-mode avalanche photodiode structure for ultra-low-level light detection. The MPPC is easily connected to an external circuit for simple operation and is operated from a low voltage power supply (typically 70 Volts).

The S11064 series is available in two pixel counts, 3600 or 14400. Each pixel contains a quenching resistor so that simultaneous photon events can be counted separately and with a high degree of accuracy. The devices feature typical gain values from 250,000 to several million, depending on the specific pixel number. They also feature high photon detection efficiency to UV and blue light, with peak sensitivity at 400 nm, making them ideal for scintillator readout. Additionally, the MPPC is insensitive to magnetic fields making it an ideal candidate for applications with more demanding environments.

The S11064 series is ideal for a variety of applications, including positron emission tomography, high-energy physics (including gamma ray detection), DNA sequencing, fluorescence measurement, nuclear medicine, point of care systems, drug discovery, medical diagnostic equipment and environmental analysis.
