摘要：
We have developed a high-density H-2 plasma source excited by helicon-wave discharge. By optimizing the antenna shape, the diameter of the discharge tube, and the magnetic field strength, a high electron density close to 1 x 10(13) cm(-3) was achieved at an rf power of 3 kW and a H-2 gas pressure of 30 mTorr. The high-density H2 plasma source can be used as a compact divertor simulator in nuclear fusion research.
