Abstract

A passive shield will be implemented on the IBIS instrument in order to reduce at low and medium energies the cosmic diffuse background and the source fluxes contribution outside the field of view. The collimator device originally proposed has been reviewed against an alternative option consisting of a box-type lateral shield. Advantages and disadvantages of the two system are analyzed in view of different optimization criteria including background, sensitivity and imaging performance as a function of energy.
