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…
HARPO: beam characterization of a TPC for gamma-ray polarimetry and high angular-resolution astronomy in the MeV-GeV range
Shaobo Wang, Denis Bernard, Philippe Bruel +23
A time projection chamber (TPC) can be used to measure the polarization of gamma rays with excellent angular precision and sensitivity in the MeV-GeV energy range through the conve…
HARPO: a TPC as a gamma-ray telescope and polarimeter
Denis Bernard, Philippe Bruel, Mickael Frotin +14
A gas Time Projection Chamber can be used for gamma-ray astronomy with excellent angular-precision and sensitivity to faint sources, and for polarimetry, through the measurement of…
