abstract = "We report the results of detailed Monte Carlo simulations of the
performance expected both at balloon altitudes and at the probable
satellite orbit of a hard X-ray coded-aperture camera being
developed for the Monitor e Imageador de RAios X (MIRAX) mission.
Based on a thorough mass model of the instrument and detailed
specifications of the spectra and angular dependence of the
various relevant radiation fields at both the stratospheric and
orbital environments, we have used the well-known package geant4
to simulate the instrumental background of the camera. We also
show simulated images of source fields to be observed and
calculated the detailed sensitivity of the instrument in both
situations. The results reported here are especially important to
researchers in this field considering that we provide important
information, not easily found in the literature, on how to prepare
input files and calculate crucial instrumental parameters to
perform geant4 simulations for high-energy astrophysics space
experiments.",
