abstract = "In this work we present the detection capability of the MIRAX
(Monitor e Imageador de RAios-X) experiment for Gamma-Ray Bursts
(GRBs). MIRAX is an X-ray astronomy mission designed to perform a
wide band hard X-ray (10-200 keV) survey of the sky, especially in
the Galactic plane. With a total detection area of 169 cm2, large
field of view (FoV, 20°×20°), angular resolution of 1°45' and good
spectral and time resolution (~8% at 60 keV, 10 \μs), MIRAX
will be optimized for the detection and study of transient
sources, such as accreting neutron stars (NS), black holes (BH),
Active Galactic Nuclei (AGNs), and both short and long GRBs. This
is especially important because MIRAX is expected to operate in an
epoch when probably no other hard X-ray wide-field imager will be
active. We have performed detailed simulations of MIRAX GRB
observations using the GEANT4 package, including the background
spectrum and images of GRB sources in order to provide accurate
predictions of the sensitivity for the expected GRB rate to be
observed. MIRAX will be capable of detecting ~44 GRBs per year up
to redshifts of ~4.5. The MIRAX mission will be able to contribute
significantly to GRB science by detecting a large number of GRBs
per year with wide band spectral response. The observations will
contribute mainly to the part of GRB spectra where a thermal
emission is predicted by the Fireball model. We also discuss the
possibility of detecting GRB afterglows in the X-ray band with
MIRAX.",
