Long pulse operation has an important impact on the design and utilization of a neutral beam injection system. This paper, first describes briefly the injectors designed for ITER FEAT as they are the first to be designed for long pulse operation under conditions approaching those that will be experienced in future machines. The important consequences of long pulse operation on the injector design will be then discussed, and finally some suggestions will be made for future, continuously operating systems.
