Status and perspectives of the ASDEX Upgrade gas inlet system

A conceptual design based on a study of operational requirements as well as available resources was developed and the gas inlet system was renewed step by step during planned maintenance shutdowns of AUG over the last years. The improvement comprises the building of a gas supply station, construction of a system for the gas assignment, relocation of the operational gas inlet and inside-vessel gas guiding as well as a redesign of the communication with the control system. Since the campaign 2014 the renewed system is in routine operation.
