Standards analog technique in experimental physics doesn't allow to achieve very high timing resolutions of the detectors based on SiPMs and fast scintillators. One of the reasonable method to obtain that more precisely is usage the digital processing algorithms.
We measured single photon timing resolution (SPTR) of a series of timing optimized KETEK SiPM samples of 3x3 mm2 and coincidence...

To determine the depth of the area of radiopharmaceutical accumulation a method based on simultaneous registration of two gamma ray lines of different energies and quantitative comparison of the intensity of these lines on the surface of the patient's body is developed. The most widely used medical radioisotope technetium-99m has two gamma-lines - 140 keV and 18 keV, which allows one to apply...

A timing scintillation detector based on a plastic scintillator tile sized 35x5x1 cm3 and SiPM optical readout has been developed and characterized. For the best uniformity of the detector’s response to particle hits across its area, a set of SiPM optical sensors has been incorporated into the scintillator throughout its volume. Time resolution better than 250 ps (sigma) has been achieved for...

Active elements in the baseline design of the highly granular calorimeters proposed for future collider experiments are scintillator tiles with silicon photomultiplier readout. The direct coupling of SiPm to scintillator is considered to be the main option for such detectors. In this study, the response of scintillator-SiPm system to minimum ionizing particle was simulated using the optical...

The detectors based on solid-state photomultipliers (SiPM) are proposed for
forthcoming experiments planned with relativistic heavy ions at FAIR
(CBM) and at NICA (MPD).
The main radiation damage of the detectors located along the beam axis is
caused by neutrons. The forward calorimeter PSD@CBM is equipped with
SiPM. The fluence up to 10e13 n/cm2 during first months
of the CBM...

The hadron endcap (HE) calorimeter is one of the major sections of CMS hadron calorimeter, which is used for measurement of the hadrons energy. Upgrade of the front-end electronics components in the existing HE calorimeter is planned for a number of reasons. New charge integrator encoder (QIE11) shunt tests and DC/DC converter calibration were carried out in preparation for HE calorimeter...

The subsystem detectors of the GlueX experiment uses the silicon photomultiplier (SiPM) photodetectors. The detectors operate in condition of 2MHz load level and up to 104 pixels «fired» with ~0.3ns time resolution. The list of such detecors : the scintillating mycroscope to determine the energy of a beam photon by detecting the bremsstrahlung electron after radiation; the magnet...

Silicon Photo-Multipliers (SiPM) are state of the art light detectors with very high single photon sensitivity and photon number resolving capability, representing a breakthrough in several fundamental and applied Science domains. So, introduction of SiPM in to the education is important process increasing the number of specialists involved in the SiPM development and application. As a result...
