  A high-energy photon polarimeter for astrophysics studies in the energy range
from 10 MeV to 800 MeV is considered. The proposed concept uses a stack of
silicon micro-strip detectors where they play the roles of both a converter and
a tracker. The purpose of this paper is to outline the parameters of such a
polarimeter and to estimate the productivity of measurements. Our study
supported by a Monte Carlo simulation shows that with a one-year observation
period the polarimeter will provide 6% accuracy of the polarization degree for
photon energies above 100 MeV, which would be a significant advance relative to
the currently explored energy range of a few MeV. The proposed polarimeter
design could easily be adjusted to the specific photon energy range to maximize
efficiency if needed.
