The GIS will provide the “initial fill” of the vacuum chamber prior to plasma initiation; it will puff gas into the chamber during the ramp-up phase; it will enable the control of plasma density during the flattop of plasma burn; and it will protect the divertor targets from discharges by injecting impurity gases. The GIS will also provide a system for the emergency shutdown of the machine.
