=== Power supply ===
 
The two high voltage power supplies feeding the acceleration grids of the injectors are of the transformer–rectifier type, taking their primary energy from a pulsed [[TJ-II:Power supply|flywheel generator]], and are coupled to the acceleration grids through a switching device.

=== Control system ===
The NBI system has its own control system.
