Study of energy and pitch angle dynamics of runaway electrons (RE) in present-day tokamak experiments requires the analysis of the RE momentum-space distribution function. Synchrotron radiation (SR) imaging using multispectral systems has proven capable of providing this information in TCV and AUG. As a consequence, the multispectral imaging system MANTIS consisting of 6 filtered cameras is planned to be installed in AUG.

Three of the filters are dedicated to SR imaging to constraint the distribution function. Since the SR is emitted along the velocity vector of the electrons, the view port needs to be carefully selected. Camera images using each filter and view are simulated using the SOFT synthetic diagnostic framework. Finally, the cameras have to be placed at a distance from the toroidal field coils and protected from the neutron flux to avoid malfunction and image noise.
