Abstract
The JEM-X experiment (Joint European X-ray Monitor, Lund et al. (1998) and Westergaard and Lund (1998)) is the X-ray monitor of the INTEGRAL satellite. It is a coded aperture, high pressure microstrip proportional counter. It will operate in the primary energy range from 3 to 35 keV (with extensions up to 100 keV), covering the central 6.6 degrees (FWHM) of the fields of view of the Imager and Spectrometer experiments. In this paper we show the latest background prediction for JEM-X, obtained by a Monte Carlo simulation based on the codes MCNP and GEANT. The local radiation environment used as input in the MCNP simulation was provided by the TIMM working group (Lei et al. 1998), based on an accurate simulation of the INTEGRAL satellite with the GEANT code. The TIMM source (secondary particles generated by cosmic rays interactions with the spacecraft) has been injected into the MCNP code and transported through a very detailed model of the JEM-X detector.
