Development status of gyrotron setup for ITER ECW system

The paper presents development status of a gyrotron setup for ITER. Twenty four such setups are to be used for heating and current drive in ITER plasma. The setup includes a gyrotron in a superconducting magnet and several tens of other components. Recently the main required gyrotron parameters were demonstrated. In the last year tests confirmed 95% reliability of gyrotron operation. Now a prototype of complete gyrotron setup is assembled and it is under thorough testing.
