問題が性能を大幅に低下させていた。In this case, the cooling path is drawn out across the center conductor and outer conductor sides of the coaxial transmission tube, which has a high potential difference, at the inlet and outlet of the cooling medium, so problems such as high frequency power leakage, dielectric breakdown, and power reflection significantly reduce performance. It was lowered to

供することにある。An object of the present invention is to provide a structure that does not require any insulating parts and does not leak radio waves when cooling a loop antenna used for high-frequency heating of plasma in a nuclear fusion device.
本発明の要点は、アース点から冷却媒体を供給するよう
にしたことにある。The key point of the invention is that the cooling medium is supplied from the ground point.

称される。An embodiment of the present invention will be described with reference to FIGS. 1 and 2. An antenna 2 and a transmission line 3 are installed near the plasma 1, and a plurality of stub tuners 4 are provided to adjust the radio waves supplied to the antenna 2 via the transmission line 3. Depending on the number of pairs of stub tuners, they are called double stubs, triple stubs, etc.

よυ熱媒体として除去処理する。The transmission line 3 has a double structure such as an inner body transmission line 3a and an outer transmission line 3b. The stub tuner 4 is in close contact with the outer periphery of its own transmission line 3a and the inner periphery of the outer transmission line 3b, and has a structure that prevents leakage of radio waves. Supplying the cooling medium from the supply port 5,
The antenna 2t passes through its own transmission line 3a1 and is cooled, and the exhaust port 6
It is removed as a heat transfer medium.

保は難しい。Figure 3 shows the conventional system.Although not shown, since the matching box and the coaxial transmission pipe through which the cooling refrigerant flows are installed separately, the internal transmission line 3a and the external transmission line 3bt-l are If insulation is required, the insulation section 7 connects the inner transmission line 3a and the outer transmission line 3.
b is insulated. In this case, insulation generally requires a withstand voltage of about 40 KV, but this is difficult to ensure due to dimensional restrictions.
