Title: HARPO: 1.7 - 74 MeV gamma-ray beam validation of a high angular resolutio n, high linear polarisation dilution, gas time projection chamber telescope and polarimeter,
Abstract: A presentation at the SciNeGHE conference of the past achievements, of the
present activities and of the perspectives for the future of the HARPO project,
the development of a time projection chamber as a high-performance gamma-ray
telescope and linear polarimeter in the e+e- pair creation regime.
