摘要

在托卡马克SST-1和Aditya-U上采用单42 ghz回旋管进行了电子回旋共振加热(ECRH)双脉冲实验。最初,该系统用于进行击穿或加热。在42 ghz回旋管系统中集成了一种具有快速上升时间和下降时间(1 ms)的新型阳极调制器电源,便于在等离子体射击中切换回旋管的多个脉冲。第一脉冲用于低环路电压下的等离子体击穿,第二脉冲用于等离子体加热。在基次谐波击穿时,第一个脉冲的功率保持在较低(小于150千瓦),而在等离子体加热时,第二个脉冲的功率超过200千瓦。在SST-1和Aditya-U两个托卡马克上进行了两次脉冲实验,Aditya-U托卡马克在第二次ECRH脉冲中明显观察到加热效应。本文讨论了在托卡马克SST-1和Aditya-U上进行的两个ECRH脉冲实验。

ECRH Two-Pulse (Breakdown and Heating) Experiments on Tokamaks Aditya-U and SST-1
Electron cyclotron resonance heating (ECRH) two-pulse experiments are carried out on the tokamaks SST-1 and Aditya-U using single 42-GHz gyrotron. Initially, the system was used to carry out either breakdown or heating. A new anode modulator power supply with fast rise time and fall time (1 ms) has been integrated with 42-GHz gyrotron system, which facilitate to switch the gyrotron for more than one pulse within plasma shot. The first pulse is used for the plasma breakdown at low-loop voltage and second pulse is used for plasma heating. The power in the first pulse is maintained low (less than 150 kW) for the breakdown at fundamental harmonic, while power in the second pulse is more than 200 kW for plasma heating. In both the tokamaks, SST-1 and Aditya-U, two pulse experiments have been carried out and heating effect is observed clearly in Aditya-U tokamak during second ECRH pulse. This article discusses about the two ECRH pulse experiments on both the tokamaks SST-1 and Aditya-U.
