In order to monitor the plasma within the Wendelstein 7-X stellarator, the IPP needed cameras capable of fitting into the tight space around the instrument and more importantly to operate reliably close to the large magnetic field necessary for the confinement. The Cygnet was successfully tested up to 1.8 Tesla and the Owl up to 2.3 Teslas. 20 Cygnet cameras in the 10 immersion tubes work and produce images surveying the divertor and the limiter region.
