A Spiral Fiber Tracker (SFT) was developed for use in E36 experiment at Japan Proton Accelerator Research Complex (J-PARC).
SFT is designed for conducting high-precision measurement of charge particles from kaon decays and consists of four layers of flat ribbons made of 1 mm diameter plastic scintillating fibers. The fibers are read out by HAMAMATSU MPPCs connected to the scintillating fibers b

A new neutron position sensitive detector was developed and tested. For neutron detection we uses LiF/ZnS-scintillation sheet. For light readout wavelength shifting (WLS) fibers used. Each end of these fibers connected with SiPM. The coordinate resolution of this detector is about 1 mm. Each scintillation sheets have efficiency 25 % for thermal neutrons. The detector can consist 2-3 sheets for mor

DC-60 is a heavy-ion accelerator (Li to Xe) with energy of 0.4-1.75 MeV/nucleon. It is used to accelerate 13C nuclei to measure the scattering cross-section of the helium on carbon-13 that is not known well and is important for the stellar astrophysics. For accurate measurements, it is important to know a beam profile within the test chamber. The poster describes preparations and setup for this me

Silicon Photomultipliers (SiPMs) are well recognised as very competitive photodetectors due to their exceptional photon number and time resolution, room-temperature low-voltage operation, insensitivity to magnetic fields, compactness and robustness. Detection of weak light pulses of nanosecond time scale appears to be the best area for SiPM applications because in this case most of the SiPM drawba

The main goal of NA62 experiment is to study extremely rare kaon decay $K^+\to \pi^+\nu\bar\nu$ with 10% precision. This decay is strongly supressed in Standard Model (SM) and could be calculated with high precision BR($K^+\to \pi^+\nu\bar\nu$) = $7.81\times 10^{−11}$ which makes it sensitive to New Physics beyond the Standard Model.
One of the important detectors of NA62 trigger system is

Creation of low-cost, portable sensors that can continuously provide information about the quality of the fuel for the tank is a very important task. Such sensors may be of interest both for car owners and manufacturers of automobile engines, as the life of an engine depends on fuel quality. One possible solution to this problem is the development of the infrared (IR) module to analyze the composi

Silicon photomultipliers (SiPM) are semiconductor single photon sensitive devices with high internal gain. They have promising applications in such areas of science as high-energy physics, cosmophysics and nuclear medicine. However, the possibility of using SiPMs in some areas is limited by radiation tolerance.

Results on the radiation hardness of avalanche photodiodes to fast neutrons are presented. APDs from Hamamatsu were irradiated with reactor neutrons up to 1 MeV equivalent fluence of $5\times 10^{14}$ n/cm$^2$ . The effects of this radiation on many parameters such as gain, intrinsic dark current, quantum efficiency, noise and capacitance for these devices are shown and discussed.

During the last years, the number of light-harvesting luminescent dendritic molecules has increased rapidly. One of the most interesting features of these molecules is a possibility of incorporation of different chromophores within one molecule that can lead to an intramolecular directional energy transfer from their peripheries to the center (a dendritic molecular antenna effect). It allows tunin
