在大型螺旋装置中，使用包括ECH在内的完整加热方案，获得了持续一分钟以上的稳定放电。用0.5-1毫瓦的NBI或ICRF维持血浆。中心等离子体温度高于1.5keV，密度保持在(1-2)×1019m-3，直至脉冲结束。碳转向器的全面安装促成了这一成就。这为下一次战役的物理和技术研究提供了充分的基础。长脉冲操作在诊断学和物理学研究中开辟了新的可能性。通过诊断参数扫描、更长时间的信号积分或二维测量，可以获得更高的准确性和可靠性。讨论了一种称为‘呼吸’的缓慢振荡的机制。进行了氢循环分析，取得了初步结果。根据这些结果，未来的计划分为两类：(I)使用长达5分钟的长脉冲放电的物理和技术实验，以及(Ii)将脉冲长度延长至1小时。
In the Large Helical Device, stable discharges lasting longer than one minute have been obtained using the complete heating scheme, including ECH. The plasma is sustained with NBI or ICRF of 0.5-1 MW. The central plasma temperature is higher than 1.5 keV with a density of (1-2) × 1019m-3 maintained until the end of the pulse. Full installation of the carbon divertor has contributed to this achievement. This provides a sufficient basis for physics and technology studies for the next campaign. Long pulse operation opens new possibilities in diagnostics and in physics studies. Higher accuracy and reliability are obtained with a diagnostics parameter scan, longer integration of signals or two dimensional measurement. The mechanism of a slow oscillation called `breathing' is discussed. Hydrogen recycling analysis has been carried out and preliminary results have been obtained. On the basis of these results, the future programme is divided into two categories: (i) physics and technology experiments utilizing long pulse discharges lasting up to 5 minutes, and (ii) extension of the pulse length up to one hour.
