The imager and spectrometer are two specially designed detectors needed to register cosmic gamma rays. The programme explains how these instruments will help in the collection of gamma rays and why this task is such a difficult one. It includes interviews with François Le Brun at CEA Saclay near Paris and with Prof. Dr Volker Schönfelder of the Max Planck Institute in Germany.
