The ion cyclotron system for the KSTAR tokamak

PDF Version Also Available for Download.

Description

The KSTAR (Korean Superconducting Tokamak Advanced Research) tokamak (Ro = 1.8 m, a = 0.5 m, {kappa} {lt}= 2, BT{lt}= 3.5 T, Ip {lt}= 2 MA, {tau} pulse {lt}= 300 s) is being constructed to do long pulse, high beta, advanced operating mode fusion physics experiments. The ion cyclotron (IC) system (in conjunction with an 8-MW neutral beam and a 1.5-MW lower hybrid system) will provide heating and current drive capability for the machine. The IC system will deliver 6 MW of rf power to the plasma in the 25 to 60 MHz frequency range, using a single four-strap antenna ... continued below

Description

The KSTAR (Korean Superconducting Tokamak Advanced Research) tokamak (Ro = 1.8 m, a = 0.5 m, {kappa} {lt}= 2, BT{lt}= 3.5 T, Ip {lt}= 2 MA, {tau} pulse {lt}= 300 s) is being constructed to do long pulse, high beta, advanced operating mode fusion physics experiments. The ion cyclotron (IC) system (in conjunction with an 8-MW neutral beam and a 1.5-MW lower hybrid system) will provide heating and current drive capability for the machine. The IC system will deliver 6 MW of rf power to the plasma in the 25 to 60 MHz frequency range, using a single four-strap antenna mounted in a midplane port. It will be used for ion heating, fast wave current drive (FWCD), and mode conversion current drive (MCCD). The phasing between current straps in the antenna will be adjustable quickly during operation to provide the capability of changing the current drive efficiency. This paper describes the design of the IC system hardware: the electrical characteristics of the antenna and the matching system, the requirements on the power sources, and electrical analyses of the launcher; IC physics requirements and analyses are covered in a companion paper.
