してなくなり効率が悪くなる。In the conventional device, as described in Japanese Patent Application Laid-Open No. 59-128797, the loop antenna was installed only around 1/4 of the plasma. Recently, loop antennas have been installed around the entire circumference in order to effectively heat the plasma. Conventionally, as shown in Fig. 3, the loop antenna was
-・There is a hole at the bottom. However, since the loop antennas A are separated and the ground point of the return conductor is shifted from the tip of the center conductor, the short circuit point of the return conductor is near zero potential B, and the magnetic field lines at the maximum current point combine with the plasma. It becomes less efficient.

二つのループアンテナは同一電源に接続されている。An embodiment of the present invention will be described with reference to FIGS. 1 and 2. A central conductor 4 is provided for heating the plasma 1 by emitting high frequency waves from the port 3 of the vacuum vessel 2 in which the plasma 1 is generated. One end of the center conductor 4 is connected to the own transmission line 8, and the other end is connected to the return conductor 5. The return conductor 5 is connected to an external transmission line 9. Local transmission line 8 and external transmission line 9
is attached to the flange 11 via the insulator 10, and the port 3
Attach to. Fara shields 6 and 7 are provided between the center conductor 4 and the plasma. The above components are collectively referred to as a loop antenna, and the same loop antenna is provided symmetrically with respect to the plasma 1. Two sets of loop antennas are attached to the turn conductor 5 by connecting pieces 12 with bolts 13. The return conductor 5 is attached to the inner wall of the vacuum vessel 2 via a seat 14. still,
The two loop antennas are connected to the same power source.
