Electron Cyclotron Power Source System For ITER

A PROPOSED NOVEL ARCHITECTURE OF EC CONTROL SYSTEM USING IEEE 802.11n NETWORK AT ITER-INDIA GYROTRON TEST FACILITY

“…The ITER-India has planned to setup an ITER-India Gyrotron Test Facility (IIGTF) at IPR campus for establishing the integrated High power Gyrotron system [7]. The Gyrotron requires High voltage power supplies (HVDC), set of auxiliary power supplies and auxiliary services for its operation.…”

Study of long-pluse high-power 170GHz gyrotron for fusion plasma ECRH

“…In International Thermonuclear Experimental Reactor (ITER), 170 GHz high-power gyrotron system with a total source power of 24 MW is planned for ECRH, ECCD and suppression of plasma instability. The development of a 170 GHz gyrotron with 1 MW, more than 400 s (typical burn time of plasma) and 50% efficiency is targeted to satisfy the requirements of the ITER [4][5] . The Japan 170-GHz ITER gyrotron achieved 1 MW, 800 s at 55% efficiency [6] .…”

Developments towards 1MW Gyrotron Test Facility at ITER-India

“…ITER requires 20 MW of RF power at 170 GHz for which 24 sets of 1MW Gyrotron sources would be required [2]. ITER-India, the Indian domestic agency has the scope of providing two Gyrotron source sets [3]. The scope includes not only the Gyrotron tubes but also the associated auxiliary systems such as the control system, auxiliary power supplies, cooling manifold etc., along with the responsibility of demonstration of performance at site on a dummy load.…”

“…The Gyrotron body circuit is represented with an equivalent RC load (350 kΩ or 850 kΩ ||1700 pF) which includes cable capacitance. A compact push-pull type solidstate switch (~ 300 x 350 x 150 mm3 ) from M/s BEHLKE is used as the fast switching element that provides the necessary fast dynamics. Some of the results obtained with this prototype setup are presented inFig.…”
