We developed an active-target type gas counter operating with low pressure He/CO2(10%) detector for application in studying low-energy nuclear reactions using radioactive beams (RNBs). A 400-μm-thick electron multiplier (THGEM) was used as the proportional high injection rate capability. examined gain stability and influence of ion feedback on particle tracks at beam rates up to 105 particles per second (pps) a 12C beam. By means modifications THGEM, shift relative pulse height output signal...

The $^{8}\mathrm{Li}(\ensuremath{\alpha},n)^{11}\mathrm{B}$ reaction is regarded as the key in inhomogeneous big bang and type-II supernova nucleosynthesis. Recently, importance of this to solving $^{7}\mathrm{Li}$ problem, i.e., inconsistency between predicted observed primordial abundances, has also been noted. most recent cross-section data published by our collaboration group 2006 [H. Ishiyama et al., Phys. Lett. B 640, 82 (2006)] cover 0.7- 2.6-MeV energy region center-of-mass system....

We report a novel, reversible, cell-permeable, pH-sensor, TRapH. TRapH afforded pH-sensitive ratiometric emission response in the pH range ∼3-6, enabling imaging and quantification of living cells. The biological-applicability was illustrated via live-tracking intracellular dynamics mammalian cells induced by synthetic H + -transporter.

A systematic study of the attenuation electromagnetic radiation in Nuclear Track Detectors (NTDs) is carried out. The gamma-ray, X-ray, UV, visible, and infrared NTDs are investigated using NaI(Tl) detector, Gas Electron Multiplier (GEM) UV-Vis spectrophotometer, FTIR spectrophotometer respectively. values some important parameters (e.g., optical depth, coefficient, etc.) three commercially available (PET, Makrofol r CR-39 ), at relevant region spectrum, determined. details experimental...

We have developed an active‐target type gas‐detector, a Gas Electron Multiplier Multiple‐Sampling and Tracking Proportional Chamber (GEM‐MSTPC) operating with low‐pressure He‐base mixed gas, where He is used as target for studies of astrophysical nuclear reaction rates. Different kinds 400 μm thick GEMs were examined. The gain stability was examined configuration in thickness fabricated different ways, against the injection rate low‐energy heavy ions 105 particles per second. GEM Cu...
