Spatial profiles of collimated laser Compton-scattering -ray beams

Takashi Ari-Izumi, Ioana Gheorghe, Dan Filipescu +3

The intensity and energy spatial distributions of collimated laser Compton scattering (LCS) -ray beams and of the associated bremsstrahlung beams have been investigated as funct…

Spectral distribution and flux of -ray beams produced through Compton scattering of unsynchronized laser and electron beams

Dan Filipescu, Ioana Gheorghe, Konstantin Stopani +4

Intense, quasi-monochromatic, polarized -ray beams produced by Compton scattering of laser photons against relativistic electrons are used for fundamental studies and applicatio…

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,…

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…
