Requirements for a large solid angle detector for ELFE

We present detailed simulations of the MEMUS detector [1] response to both electromagnetic and hadronic background, as well as to a representative set of proposed experiments at ELFE. The aim of this study is to check the adequation of the detector to the requirements of the experiments involving exclusive channels. This study is far from complete, but preliminary design refinements can be inferred. The technical details for the detector components can be found in the write-up of the detector session[2].
