On the Angular Resolution of Pair-Conversion -Ray Telescopes
Denis Bernard
I present a study of the several contributions to the single-photon angular resolution of pair telescopes in the MeV energy range. I examine some test cases, the presently active {…
MeV-GeV Polarimetry with : Asserting the Performance of Silicon Strip Detectors-Based Telescopes
Denis Bernard
The polarimetry of gamma rays converting to an pair would open a new window on the high-energy gamma-ray sky by, among other things, providing insight into the radiation m…
Performance of the MeV gamma-ray telescopes and polarimeters of the future. in silicon-detector active targets
Denis Bernard
A number of techniques are being developed to solve the monstrous sensitivity gap that exists between the energy ranges of good sensitivity of the Compton and of the pair telescope…
HARPO, a gas TPC active target for high-performance -ray astronomy; demonstration of the polarimetry of MeV -rays converting to pair
Denis Bernard
No -ray polarimeter sensitive above 1 MeV has ever flown space. -ray polarimetry would be a new window on the radiative processes at work in cosmic sources, processes that pr…
Calorimeter-less gamma-ray telescopes: Optimal measurement of charged particle momentum from multiple scattering by Bayesian analysis of Kalman filtering innovations
Denis Bernard, Mikael Frosini
Novel gamma-ray telescope schemes (silicon wafer stacks, emulsions, gas detectors) are being developed so as to bridge the sensitivity gap between Compton and pair-creation telesco…
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…
