固体増幅器の核融合への適用の現状とクライストロードの開発

抄録

The radio frequency (RF) systems in fusion plasma heating often use broadcasting transmitter techniques. For example, the RF heating system in JT-60 was built using broadcasting technology. Also, a new, high efficiency UHF power amplifier electron tube, the Klystrode, which was developed in the USA for TV can be used for fusion plasma systems. While Japanese broadcasting engineers had an effort to develop solid state UHF amplifiers with high power, the USA is developing new high power tubes such as the klystrode. In this paper we will discuss the feasibility of applying a solid state amplifier and klystrode for fusion plasma heating.
