摘要:The design of the bleeder circuit of the photomultiplier tubes for Hyper-Kamiokande was optimized to satisfy required specifications. We achieved the wide dynamic range over 1,000 photo-electrons. We also confirmed the gain stability within 10% change for the light amount up to 6...

摘要:We outline recent developments in the experimental studies of the EMC effect which suggest that the proton–neutron short range correlations (SRC) play dominant role in the EMC effect. In combination with experimental evidence that the SRC are predominantly nucleonic these ob...

摘要:The continuous electron beam accelerator facility at Jefferson Lab, built with advanced superconducting radiofrequency (SRF) technology, provides opportunities to discover fundamental new aspects of the structure of visible matter — protons, neutrons, and other states, and o...

摘要:SiPM operation at very low temperatures has the potential to improve detector systems for experiments at cryogenic temperatures. We characterized electrical and optical properties of a commercially available cryogenic SiPM over a temperature range of 6.5–286 K, such as break...

摘要:The critical point in particle physics at high temperature is studied through the ideal gas of scalars, the dilatons, in the model that implies the spontaneous breaking of an approximate scale symmetry. We found the critical temperature as a function of a dilaton mass, and the fl...

摘要:A high-radiation resistant optical fiber has been developed in order to investigate the interiors of the reactor pressure vessels and the primary containment vessels at the Fukushima Daiichi Nuclear Power Station. The tentative dose rate in the reactor pressure vessels is assumed...

摘要:We have investigated the convergence of kaon photoproduction amplitude by expanding the square of the amplitude in terms of the ratio mK / m , where mK is the mass of kaon and m is the averaged mass of nucleon and Λ-hyperon. The amplitude is calculated ...
