Novel Silicon Photomultipliers for PET Applications

IEEE Transactions on Nuclear Science, 2008
Silicon photomultipliers (SiPMs) with quantum efficiency maximized for a wavelength between 420 and 470 nm have been developed at ITC-irst Trento (Italy), and are being tested for their application in the construction of a ultra high resolution small animal PET tomograph. The devices have an area of 1 mm times 1 mm and 625 microcells.

Interpolating silicon photomultipliers

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2013
Abstract We present the novel Interpolating Silicon PhotoMultiplier (ISiPM) concept which provides the spatial position of photon clusters with high resolution. Individual APD cells of the ISiPM area are not connected to a common readout electrode, but each cell is connected to one of several output channels. The most straight forward embodiment is a

Development of Silicon PhotoMultipliers at FBK-irst

Il Nuovo Cimento C, 2007
We report on the development of Silicon PhotoMultipliers (SiPM) at the Fondazione Bruno Kessler (FBK)-irst (Trento, Italy) in the framework of a collaboration with INFN. Device geometry and technology are resumed, and selected results from the characterization of SiPM prototypes from three production batches are reported, including static, dynamic, and

Optimized silicon photomultipliers with optical trenches

2011 Proceedings of the European Solid-State Device Research Conference (ESSDERC), 2011
This paper reports on the electrical characteristics of silicon photomultipliers (SiPM) with optimized optical trench technology. The SiPM arrays were characterized from single pixels up to the full 64×64 pixel device. The data clearly show a perfect scaling of the dark current with the pixel number, thus indicating an almost ideal insulation among the

Silicon Photomultipliers - End of the Photomultiplier Tubes Era

LEOS 2007 - IEEE Lasers and Electro-Optics Society Annual Meeting Conference Proceedings, 2007
The principle of silicon photomultipliers (SiPM) is discussed. The SiPM structure is based on the array of submicron semiconductor micro-cells, working in breakdown mode with integrated quenching elements and common electrode. The characteristics and the operational conditions of the SiPM is presented.

CY5 fluorescence measured with silicon photomultipliers

2014 IEEE Biomedical Circuits and Systems Conference (BioCAS) Proceedings, 2014
This paper presents an efficient optical biosensor set up for a low-level light detection, using fluorescent dyes and a novel Si-based detector. Fluorescence emitted by a traditional fluorophore, CY5, widely used as optical label in DNA microarrays, was detected using a 25 pixels Silicon photomultiplier (SiPM), a device formed by avalanche diodes ...

Comparison of NaI coupled to photomultiplier tube and silicon photomultiplier

2018 IEEE Nuclear Science Symposium and Medical Imaging Conference Proceedings (NSS/MIC), 2018
The NaI scintillator has been widely used for decades. In recent years, the silicon photomultiplier (SiPM), a new photosensor based on semiconductor technologies, has attracted a great deal of attention and has started replacing the conventional photomultiplier tube (PMT) in some applications.
