Optical design study of an infrared visible viewing system for Wendelstein 7-X divertor observation and control
For the Wendelstein 7-X stellarator, which will allow quasicontinuous operation ( τ ≤ 30 min ) with 10 MW of electron cyclotron radiation heating power, a conceptual design study for an IR/visible viewing system (IVVS) has been elaborated. Ten such systems, as part of the machine protection system...

with 10 MW of electron cyclotron radiation heating power, a conceptual design study for an IR/visible viewing system (IVVS) has been elaborated. Ten such systems, as part of the machine protection system, will be required for real time monitoring of all ten discrete, water cooled divertor modules with high spatial
