为了研究束流慢化时间随温度和密度的变化规律，在DIII-D托卡马克装置上注入了较短的氢束脉冲。慢化时间是由d(d，n)3He中子辐射的衰减率推断出来的。在∼为30%的范围内，计算结果与齐武欣的经典理论基本一致。短束脉冲对于测量中心的氚密度也很有用。
Short deuterium beam pulses are injected into the D III–D tokamak to study the variation of beam slowingdown time with temperature and density. The slowing-down time is inferred from the rate of decay of the d(d,n)3He neutron emission. To within ∼30%, the results are consistent with Sivukhin's classical theory. The short beam pulses,are also useful for measurements of the central deuterium density.
