Development of New Tracking Detector with Fine-grained Nuclear Emulsion for sub-MeV Neutron Measurement
T. Shiraishi, I. Todoroki, T. Naka +3
In this study, we have developed a new sub-MeV neutron detector that has a high position resolution, energy resolution, directional sensitivity, and low background. The detector is…
Optical shape analysis based on discrete Fourier transform and second order moment calculation of the brightness distribution for the detection of sub-micron range low energy tracks
Atsuhiro Umemoto, Tatsuhiro Naka, Toshiyuki Nakano +3
To recognize sub-micron range low energy tracks recorded in a super fine grained nuclear emulsion (Nano Imaging Tracker), an elliptical fitting method was devised to analyze anisot…
Super resolution plasmonic imaging microscopy for submicron tracking emulsion detector
Atsuhiro Umemoto, Tatsuhiro Naka, Andrey Alexandrov +1
NIT is a super fine-grained nuclear emulsion which has a detection capability for ionizing particle with nanometric resolution and record the track by a line of silver nanograin wi…
A Cold/Ultracold Neutron Detector using Fine-grained Nuclear Emulsion with Spatial Resolution less than 100 nm
N. Naganawa, T. Ariga, S. Awano +9
A new type of cold/ultracold neutron detector that can realize a spatial resolution of less than 100 nm was developed using nuclear emulsion. The detector consists of a fine-graine…
Fundamental physics activities with pulsed neutron at J-PARC(BL05)
Kenji Mishima, Shogo Awano, Yasuhiro Fuwa +37
"Neutron Optics and Physics (NOP/ BL05)" at MLF in J-PARC is a beamline for studies of fundamental physics. The beamline is divided into three branches so that different experiment…
Discovery potential for directional Dark Matter detection with nuclear emulsions
N. Agafonova, A. Aleksandrov, A. Anokhina +53
Direct Dark Matter searches are nowadays one of the most fervid research topics with many experimental efforts devoted to the search for nuclear recoils induced by the scattering o…
A neutron detector with spatial resolution of submicron using fine-grained nuclear emulsion
N. Naganawa, S. Awano, M. Hino +9
We have been developing a neutron detector with spatial resolution of submicron by loading 6Li into fine-grained nuclear emulsion. By exposure to thermal neutrons, tracks from neut…
Readout technologies for directional WIMP Dark Matter detection
J. B. R. Battat, I. G. Irastorza, A. Aleksandrov +90
The measurement of the direction of WIMP-induced nuclear recoils is a compelling but technologically challenging strategy to provide an unambiguous signature of the detection of Ga…
NEWS: Nuclear Emulsions for WIMP Search
A. Aleksandrov, A. Anokhina, T. Asada +56
Nowadays there is compelling evidence for the existence of dark matter in the Universe. A general consensus has been expressed on the need for a directional sensitive detector to c…
Intrinsic neutron background of nuclear emulsions for directional Dark Matter searches
A. Alexandrov, T. Asada, A. Buonaura +24
Recent developments of the nuclear emulsion technology led to the production of films with nanometric silver halide grains suitable to track low energy nuclear recoils with submicr…
Observation of nu_tau appearance in the CNGS beam with the OPERA experiment
OPERA Collaboration, N. Agafonova, A. Aleksandrov +145
The OPERA experiment is searching for nu_mu -> nu_tau oscillations in appearance mode i.e. via the direct detection of tau leptons in nu_tau charged current interactions. The evide…
