【摘要】 <正> 一、引言 在现行的托卡马克实验中,辐射损失和中性粒子损失是高温等离子体能量损失的主要通道之一。为了更好地了解托卡马克等离子体中能量平衡、辐射损失以及这些损失随等离子体参数的变化;了解等离子体中杂质含量和杂质输运以及等离子体与器壁的相互作用,辐射能量损失的时间特性、空间分布的测量显得很有必要。为更多还原

【Abstract】 This paper discribes the structure,methods of calibration and measurement system of a metal foil resistor bolometer which is developed for measuring the radiation power of high,temperature plasmas.The radiation loss and neutral flux loss ia HT-6B tokamak have been measured by using the bolometer.The following results were obtained; (1) A large,nearly constant fraction (~50%) of the input power was lost to the wall by radiation and energetic neutrals during the quasisteady phase of a normal,discharge; (2) The power loss linearly increased with the discharge current Ip (3) During disruption,most of the plasma energy was lost by radiation and neutrals.更多还原
