本文介绍一个用于秒级半衰期核素测量的简单传送带装置。把反应产物收集到一条镀铝Mylar箔上,然后极快地传送到测量点进行测量。带子运行时,靶室真空从2.67mPa降至6.67mPa,带子停止后靶室真空立即恢复。文中还给出了测得的

≥1 s was described. The reaction products are collected on a Mylar foil
which was then transported immediately to the measurement spot. The vacuum in the reaction chamber was 2.67 mPa and while the tape was pulled the vacuum decreased to 6.67 mPa. The vacuum was recovered immediately to the original value when the tape's movement is stopped. a
