We have measured the 3d→2p transition x rays of kaonic ^{3}He and ^{4}He atoms using superconducting transition-edge-sensor microcalorimeters with an energy resolution better than 6 eV (FWHM). determined energies to be 6224.5±0.4(stat)±0.2(syst) 6463.7±0.3(stat)±0.1(syst) eV, widths 2.5±1.0(stat)±0.4(syst) 1.0±0.6(stat)±0.3(stat) for ^{4}He, respectively. These values are nearly 10 times more precise in previous measurements. Our results exclude large strong-interaction shifts that suggested...
A novel concept to enhance the photo-detection efficiency (PDE) of silicon photomultipliers (SiPMs) has been applied and remarkable positive results can be reported. This uses arrays microlenses cover every second SiPM pixel in a checkerboard arrangement aims deflect light from dead region pixelised structure towards active center pixel. The PDE is improved up 24%, external cross-talk reduced by 40% compared flat epoxy layer, single photon time resolution improved. detector development...
The interaction of antikaons with nucleons and nuclei in the lowenergy regime is a very active research field hadron physics. Specially, antikaon-nucleon close to threshold provides crucial information on interplay between spontaneous explicit chiral symmetry breaking low-energy QCD touching one fundamental problems physic today - still unsolved question how masses are generated. To study this problem, we have developed new X–ray detector system constructed an experimental apparatus measure...
The kaonic deuterium measurement at J-PARC and DAΦNE will provide a piece of information still missing to the antikaon-nucleon interaction close threshold, providing valuable answer one most fundamental problems in hadron physics today - yet unsolved puzzle how mass is generated. For this new X-ray detector system has been developed measure shift width 2p → 1s transition with precision 60 eV 140 eV, respectively.
