Silicon Photomultipliers (SiPMs) offer an alternative to PMTs that allow the implementation of innovative detector types. Continuous scintillator crystals coupled to SiPM arrays provide higher efficiency than pixellated crystals. We are applying this approach in two different medical imaging fields with successful results.
The use of SiPM arrays makes it possible stacking several detector...

SiPMs are nowadays available from varying manufacturers. The investigated device was the latest KETEK PM3350. Its peak sensitivity is for blue light, it has an active area of 3 x 3 mm² with 50 µm cell size and operates in a large bias region from 24 - 32 V. The active area is covered with an epoxy layer and the package is kept at the smallest possible size of 3.9 x 4.4 x 2.0 mm³

We are developing a PET scanner which has both depth-of-interaction (DOI) and time-of-flight (TOF) information and can be placed close to a MRI scanner. Here we evaluated the positioning and energy performances of a four-layer DOI detector which consists of a single-layer of a 16 x 16 Lu2(1-x)Gd2xSiO5 (LGSO) crystal array, a light guide, and a 6 x 6 SiPM (MPPC: S10985-050C, Hamamatsu...

Intraoperative localization of malignant tissues labeled with positron radiotracers opens up new prospects to improve the efficiency of cancer surgery. Because Silicon Photomultipliers (SiPM) introduced a breakthrough for the development of miniaturized imaging devices, we are currently designing two intraoperative beta probes based on this technology: a light imaging device with a small field...

This article describes performance of a new generation of the Micro-Pixel Avalanche Photodiode (MAPD). MAPD has the especially advances: gain can reach values of 105, photon detection efficiency is 30-35 % in a wide wavelength range and pixels density is 15000 pixels/mm2. Results of gamma-ray detecting measurements performed using LFS scintillating crystal by MAPD are also presented. Energy...

We have recently published [1] a time resolution study with a plastic scintillator read out by a~Geiger-mode Avalanche Photodiode. Time resolution of sigma = 18/(E^0.5) ps*MeV^0.5 was measured. The work presented here aims to simulate that experiment using the Geant4 toolkit, and to identify the parameters which have the largest effect on the total time resolution. We also compare different...

Hyper-Kamiokande is a huge Cherenkov neutrino detector with water of 1 million metric tons planned for the near future in Japan. Several Photo-Detector (PD) candidates are being newly developed. At first, an 8-inch Hybrid-PD with an avalanche diode will be tested in a 200-ton water Cherenkov detector loaded with Gadolinium. We report the plan and status, as well as the basic performance...

Visible light emission from both photomultipliers (PMT) and semiconductor p-n junctions in reverse bias has been known for over half a century. As photomultipliers and silicon photomultipliers (SiPM) are sensitive, their own light emission has a feedback, which needs to be understood. Furthermore it can be used to develop new evaluation tools.
With light emission microscopy we can show that...

This work presents a miniaturized photo-detection system based on a new semiconductor photon-detector namely SiPM and a special read-out electronics build around a dedicated ASIC.
The used SiPM arrays have important advantages compared to classical photomultipliers tubes (compactness, good sensitivity, low bias voltage) and the ASIC’s read-out electronics developed at LAL offers...

The domain of Geiger-APD has reached an advanced development in the last years. The idea of this work is to use the spatial resolution and rapidity of the Geiger-APD in the field of very low light intensities; it would be possible to explore new areas. The equipment that we intend to achieve will be a series of Geiger-APD arrays (imagers) based on the principle detector unit.

We are presenting a set of measurement to determination of the optical to electrical delay of the photon counting detector. The absolute value of the time interval between the time of arrival of the signal photon onto the detector input aperture and the time when the electrical output signal is exceeding the predefined level have to be determined. Also results showing a temporal relation...

High position and timing resolutions can be simultaneously achieved today using scintillation material coupled with SiPM.
An active target for the MEG experiment based on very thin scintillating fibers readout by SiPMs operating in a high magnetic field (1.3 T) is considered. The tool should provide a very precise measurement of the muon decay vertex and its timing, with a consequently...

Positron Emission Tomography (PET) is a medical imaging technique able to observe functional processes in vivo. It is based on the simultaneous back-to-back emission of the two 511 keV photons following positron annihilation by a chemical tracer doped with appropriate radioisotopes. The possibility to use high timing resolution detectors allows to localize the emission source with higher...

Time resolved imaging up to the single photon sensitivity is one of the most ambitious and important goals of photonics. Currently there are no commercial devices able to provide both the information on position (imaging) and arrival time of photons emitted by weak and ultra-weak source. Only very expensive sensors (ICCD) are able to reach the single photon threshold with the possibility to...
