软X射线的锯齿振荡,在ST,Pulsator和TEXT等装置上已观测到;在Pulsator和PLT上已研究了硬X射线锯齿波。PLT和Pulsator观测结果为,产生的硬X射线锯齿振荡为反锯齿和内破裂的软X射线锯齿相对应。Pulsator的硬X射线锯齿和软X射线锯齿一样,这种趋势一直持继到放电结束,而硬X射线峰值发生在软X射线内破裂后大约200μs。PLT的硬X射线锯齿比软X射线锯齿延迟1至5ms。本工作目的是在内破裂后,从软、硬X射线锯齿波对比,观测硬X射线到达峰值这段延迟时间,并以此来量度逃逸电子约束时间。
Sawtooth oscillations of soft X-rays have been observed on ST, Pulsator, and TEXT devices; hard X-ray sawtooth waves have been investigated on Pulsator and PLT. PLT and Pulsator observations showed that the resulting hard X-ray sawtooth oscillations correspond to anti-aliased and internally fractured soft X-ray saw teeth. The Pulsator’s hard X-ray sawtooth, like soft X-ray sawtooth, persisted until the end of the discharge, whereas the hard X-ray peak occurred about 200 μs after soft X-ray rupture. Hard X-ray saw teeth of PLT are delayed by 1 to 5 ms compared to soft X-ray saw teeth. The purpose of this work is to compare the delay between hard and hard X-ray sawtooth waves and the peak hard X-ray arrival time after rupture, and to measure the escape time of electron confinement.
