Energy deposition on nuclear emulsion by slow recoil ions for directional dark matter searches
Akira Hitachi, A. Mozumder, Kiseki D. Nakamura
The electronic energy deposited on nuclear emulsions due to C ions of 5 -- 200~keV and Kr ions of 5 -- 600~keV are evaluated and compared with those due to fast ions for design and…
Properties for liquid argon scintillation for dark matter searches
Akira Hitachi, A. Mozumder
The scintillation yield for recoil Ar ions of 5 to 250 keV energy in liquid argon have been evaluated for direct dark matter searches. Lindhard theory is taken for estimating nucle…
Cornu's spiral in the Fresnel regime studied using ultrasound: A phase study
Akira Hitachi
A simple experimental technique for measuring the phase and amplitude of diffracting ultrasound wave [A. Hitachi and M. Takata, Am. J. Phys. 78, 678 (2010)] has been applied to dif…
Babinet's principle in the Fresnel regime studied using ultrasound
Akira Hitachi, Momo Takata
The diffraction of ultrasound by a circular disk and an aperture of the same size have been investigated as a demonstration of Babinet's principle in the Fresnel regime. The amplit…
Bragg-like curve for dark matter searches; binary gases
Akira Hitachi
The directional detection of low-energy recoil ions can provide strong possibility for observation of dark matter in the Galaxy. Quenching factors for 5-200 keV recoil ions in N2,…
Measurement of the refractive index and attenuation length of liquid xenon for its scintillation light
V. N. Solovov, V. Chepel, M. I. Lopes +3
The attenuation length and refractive index of liquid xenon for intrinsic scintillation light (178nm) have been measured in a single experiment. The value obtained for attenuation…
