Abstract

During the first part of the active phase of JET, the Deuterium and Tritium Experiment 1 (DTE1), the tritium was delivered to the plasma mainly by neutral beam injection. T₂ and D₂ were delivered from U beds in the active gas handling system (AGHS) and were introduced to the Positive Ion Neutral Injectors (PINIs) at ground potential via a new specially developed Tritium and Deuterium Gas Introduction System (TDGIS). This paper describes the function of the TDGIS, the installation and the commissioning of the system. It also describes the operation of the neutral beam system up to 160 kV with tritium beams
