Evidence for a quasi-bound state in the reaction
R. Kobayakawa, J. K. Ahn, S. Ajimura +34
The reaction has been studied to search for a quasi-bound state using the LEPS2 solenoid spectrometer at SPring-8. A localized enhancement concentrated…
First observation of the -ray beam production by the backward Compton scattering of reflected synchrotron radiation in the extreme ultraviolet range
Norihito Muramatsu, Manabu Miyabe, Masahiro Okabe +8
Compton scattering of photons off high-energy electrons is a fundamental quantum mechanical process widely utilized to produce a -ray beam for scientific research. Instead of in…
SPring-8 LEPS2 beamline: A facility to produce a multi-GeV photon beam via laser Compton scattering
N. Muramatsu, M. Yosoi, T. Yorita +48
We have constructed a new laser-Compton-scattering facility, called the LEPS2 beamline, at the 8-GeV electron storage ring, SPring-8. This facility provides a linearly polarized ph…
Performance measurement of HARPO: a Time Projection Chamber as a gamma-ray telescope and polarimeter
P. Gros, S. Amano, D. Attié +27
We analyse the performance of a gas time projection chamber (TPC) as a high-performance gamma-ray telescope and polarimeter in the ee pair creation regime. We use data coll…
First measurement of polarisation asymmetry of a gamma-ray beam between 1.74 to 74 MeV with the HARPO TPC
Philippe Gros, Sho Amano, David Attié +23
Current -ray telescopes suffer from a gap in sensitivity in the energy range between 100keV and 100MeV, and no polarisation measurement has ever been done on cosmic sources abov…
Measurement of 1.7 to 74 MeV polarised gamma rays with the HARPO TPC
Y. Geerebaert, Ph. Gros, S. Amano +23
Current γ-ray telescopes based on photon conversions to electron-positron pairs, such as Fermi, use tungsten converters. They suffer of limited angular resolution at low energies,…
