Silicon Photomultipliers

News

IRIS will be at the Single Photon Workshop 2015 in Geneva, from 13th to 17th of July, to present the latest developments in silicon photomultiplier technology.

You are invited to meet us and attend our talk entitled "High-density cell and high-efficiency Silicon Photomultipliers", presented by Fabio Acerbi.

See you there!

We recently developed a new high-density version of NUV-SiPM, called NUV-HD. Like RGB-HD the devices feature a high fill factor (FF) and a reduced correlated noise.

This new NUV-HD technology combined all the benefits of the HD technology, like high FF, increased photon detection efficiency, low correlated noise and high cell-density (thus high dynamic range), with the advantages of NUV approach for light detection un the blue and near-UV wavelength region.

Projects

Molecular imaging (MI) and Proton Therapy (PT) have become fundamental tools for the diagnosis and treatment of diseases such as cancer. Innovation in this field is very strong aiming at improving the imaging capability. The most important development over the last few years is the use of a novel solid-state photo-detector (Silicon Photomultipliers, SiPMs) that can replace the traditional vacuum-based photo-multiplier tubes. This sensor opens the possibility to combine different imaging modalities and to develop compact, light and portable systems with higher performance.

Main activities

The IRIS activity on Silicon Photomultipliers leads to the development of new SiPM technologies, aimed the the optimization of different detector parameters, such as the Dark Count Rate, the Breakdown Voltage uniformity, the Photo Detection Efficiency, the Excess Noise Factor and the Dynamic Range.
