在ＨＩ－１３串列加速器上建立了我国第一台氚气体靶装置。氚气体靶采用双窗结构，入射窗为Ｍｏ箔。Ｍｏ窗把气室分成氚气室和氦气室两部分。实验运行时，氚气室的氚气压力为２×１０５Ｐａ，氦气室的氦气压力为３×１０４Ｐａ。氚气体靶装置在入射氘束流能量为２０ＭｅＶ、流强１．５μＡ时，可长时间安全运行。该靶装置已应用于中子物理的实验测量工作。 The first tritium gas target device in China was established on the HI-13 tandem accelerator. Tritium gas targets using dual-window structure, the entrance window Mo foil. Mo window divides the gas chamber into tritium gas chamber and helium gas chamber. In the experimental run, the tritium gas pressure in the tritium gas chamber is 2 × 10 5 Pa and the helium pressure in the helium gas chamber is 3 × 10 4 Pa. Tritium gas target device in the incident deuterium beam energy of 20MeV, 1.5μA flow intensity, can be a long time safe operation. The target device has been applied to the experimental measurement of neutron physics.
