Relativistic runaway electrons (RE) with energies in the MeV range can be generated during tokamak disruptions. A RE beam carrying multiple MAs of current poses an intolerable risk to plasma facing components. To explore RE dynamics imaging diagnosis techniques have been explored in the past [1, 2]. Recently, a multi-spectral imaging system MANTIS [3] has been successfully commissioned in AUG. This system is utilized to record the synchrotron spot evolution produced by the RE beam across a number of discharges. An overview of the installation, challenges and lessons learned is offered. Additionally, results from the commissioning and operation phases are presented and discussed qualitatively. [1] M.
