ABSTRACT
MGEANT is a multi-purpose simulation package based on the CERN GEANT package and Program Library. This package allows for the rapid prototyping of a wide variety of gamma-ray detector systems. The two main advantages of this package over standard GEANT simulations are 1) the detector geometry and material data are supplied via input files instead of being hard coded and 2) MGEANT has several built in spectral and beam options including the ability to simulate observations with multiple pointings and diffuse sources. We are currently using MGEANT to produce detailed observation simulations and response matrices for INTEGRAL/SPI. We present a sample of the type of work that has been done at GSFC using MGEANT simulations. This software package is available from our website http://lheawww.gsfc.nasa.gov/docs/gamcosray/legr/integral/. © 2000 American Institute of Physics.

    Collimators are usually needed to image sources emitting X-rays that cannot be focused. Alternately, one may employ a Compton Camera (CC) and measure the direction of the incident X-ray by letting it interact with a thin solid, liquid or gaseous material (Tracker) and determine the scattering...

    The photographic all-sky patrol network operated by the Ondrejov Observatory and based on 11 stations in the Czech Republic still represents one of very few possibilities to get real-time simultaneous optical data (no delay with respect to the GRB emission) and even pre-burst data for GRBs.

The standard likelihood analysis applied to EGRET data requires the photons to be binned spatially and in...
