First results on the search for the Galactic Center Excess in the sub-GeV band with the emulsion telescope in GRAINE 2023
Yuya Nakamura, Shigeki Aoki, Takashi Azuma +34
(Please check the paper for full abstract.) The Galactic Center Excess (GCE) is an unexplained excess of gamma-ray emission from the Galactic Center. The GRAINE experiment aims to…
First overnight balloon flight of the GRAINE 2023 emulsion gamma-ray telescope enabled by a large-scale pressure-vessel gondola
Hiroki Rokujo, Shigeki Aoki, Takashi Azuma +34
The Gamma-Ray Astro Imager with Nuclear Emulsion (GRAINE) project conducts precision observations of sub-GeV--GeV cosmic gamma rays using a balloon-borne nuclear-emulsion telescope…
Measurement of reconstructed final-state kinematics in charged-current interactions on water using the J-PARC beam and NINJA emulsion detector
NINJA Collaboration, A. Kasumi, S. Han +50
We present a study of charged-particle multiplicities and the kinematic distributions of muons, protons, and charged pions in a flux-integrated sample of charged-current inclusive…
New high-precision measurement system for electron-positron pairs from sub-GeV/GeV gamma-rays in the emulsion telescope
Yuya Nakamura, Shigeki Aoki, Tomohiro Hayakawa +27
The GRAINE project observes cosmic gamma-rays, using a balloon-borne emulsion-film-based telescope in the sub-GeV/GeV energy band. We reported in our previous balloon experiment in…
Measurements of protons and charged pions emitted from charged-current interactions on iron at a mean neutrino energy of 1.49GeV using a nuclear emulsion detector
H. Oshima, T. Matsuo, A. Ali +45
This study conducted an analysis of muons, protons, and charged pions emitted from charged-current interactions on iron using a nuclear emulsion detector. The emulsion detect…
Wide angle acceptance and high-speed track recognition in nuclear emulsion
Y. Suzuki, T. Fukuda, H. Kawahara +5
A nuclear emulsion film is a three-dimensional tracking device that is widely used in cosmic-ray and high energy physics experiments. Scanning with a wide angle acceptance is cruci…
First measurement using a nuclear emulsion detector of the charged-current cross section on iron around the 1GeV energy region
H. Oshima, T. Matsuo, A. Ali +43
We have carried out charged-current interaction measurement on iron using an emulsion detector exposed to the T2K neutrino beam in the J-PARC neutrino facility. The data samp…
First measurement of and charged-current inclusive interactions on water using a nuclear emulsion detector
A. Hiramoto, Y. Suzuki, A. Ali +40
This paper reports the track multiplicity and kinematics of muons, charged pions, and protons from charged-current inclusive and interactions on a water target, mea…
First demonstration of gamma-ray imaging using balloon-borne emulsion telescope
Hiroki Rokujo, Shigeki Aoki, Kaname Hamada +30
We promote the precise gamma-ray observation project Gamma-Ray Astro-Imager with Nuclear Emulsion (GRAINE), which uses balloon-borne emulsion gamma-ray telescopes. The emulsion tel…
Hyper-track selector nuclear emulsion readout system aimed at scanning an area of one thousand square meters
Masahiro Yoshimoto, Toshiyuki Nakano, Ryosuke Komatani +1
Automatic nuclear emulsion readout systems have seen remarkable progress since the original idea was developed almost 40 years ago. After the success of its full application to a l…
First demonstration of emulsion multi-stage shifter for accelerator neutrino experiment in J-PARC T60
K. Yamada, S. Aoki, S. Cao +47
We describe the first ever implementation of an emulsion multi-stage shifter in an accelerator neutrino experiment. The system was installed in the neutrino monitor building in J-P…
First neutrino event detection with nuclear emulsion at J-PARC neutrino beamline
T. Fukuda, S. Aoki, S. Cao +47
Precise neutrino--nucleus interaction measurements in the sub-multi GeV region are important to reduce the systematic uncertainty in future neutrino oscillation experiments. Furthe…
