The silicon photomultiplier (SiPM) is a novel photon detector based on Geiger mode operating avalanche photodiodes. In this paper, we present results from a test, demonstrating the feasibility of ...SiPM as readout elements in scintillator-based positron emission tomography (PET). As scintillator we use the newly developed LYSO crystals having similar characteristics as LSO. With our setup we measure an energy resolution of about 22% and a time resolution of a single crystal element of

, both full-width at half-maximum. A significant improvement in time resolution could be achieved by triggering on the first photoelectron in the signal. We also present the coincidence rate of two detector channels vs. the position of a small point-like

The Silicon Photomultiplier (SiPM) is a semiconductor device consisting of many photon microcounters (103mm−2) positioned on a common Si substrate. SiPM operates in a limited Geiger mode and has ...single photoelectron gain (106) and photon detection efficiency (20%) similar to vacuum PMT. Main SiPM features are described and a number of examples of its possible applications are demonstrated, such as scintillator fiber readout, scintillator tiles+WLS readout, imaging Cherenkov counter timing. These SiPM applications are based on experimental test data and SiPM performance is compared with other photodetectors (PMT, APD, HPD, VLPC).

Recent results on Limited Geiger-mode Microcell Silicon Photodiode (LGP) are described. Two new modifications of LGP have been designed and produced. Each of them consists of 104 pixels 10×10μm2 size ...with area of 1mm2. These pixels operate as an independent photon counters, giving the output signal as a sum of the signals from pixels fired by photons. The effective “gain” is large (≈105). The efficiency of the visible light photon detection of few percents has been measured. Low-temperature dark rate dependence has been studied. The timing by LGP at the level of 100 ps (FWHM) was found.
We report on the design, construction and performance of a prototype for a high-granularity tile hadronic calorimeter for a future international linear collider detector. Scintillating tiles are read ...out via wavelength-shifting fibers that guide the scintillation light to a novel photodetector, the silicon photomultiplier. A prototype has been tested using a positron test beam at DESY. The results are compared with a reference prototype calorimeter equipped with multichannel vacuum photomultipliers. Detector calibration, noise, linearity and stability are discussed, and the energy response in a 1–6
GeV positron beam is compared with simulations. The present results demonstrate that the silicon photomultiplier is well-suited as photodetectors in calorimeters and thus has been selected for the construction of a

Transition Radiation Detector based on the usage of thin scintillators (Sci-TRD) is proposed for particle identification. Such type of TRD may be especially interesting for space apparatus because of ...no gas. The proposed detector is based on the thin transparent films with incorporated micro-granules of Lu2SiO5:Ce scintillator. Scintillation signal produced by absorbed TR photons is registered by SiPM connected to WLS fibers. Results of measurements with samples of such films are presented. The clear signals from 55Fe (∼5keV) and 241Am (∼16keV) gamma sources were observed. The detailed Monte Carlo simulations of such kind of TRD are also presented.
The novel type of the Silicon Photodiode — Limited Geiger-mode Photodiode (LGP) has been produced and studied. The device consists of many ≈10

We discuss the silicon photomultiplier as a novel photon detector for the Major Atmospheric Gamma Imaging Cerenkov Telescope and the Extreme Universe Space Observatory. For these astroparticle ...experiments we pursue two different developments of the SiPM. One development is pursued at MEPhI, where prototypes are available. In the course of this paper we will describe some characteristics of these devices. The second development, which is using the back illumination principle is at present in its design phase.
