气体温度低于室温的等离子体尚未完全被理解，尽管它有望成为一种有吸引力的材料加工应用工具。本文研究了低温等离子体射流的气体温度依赖产生。到目前为止，我们已经在大气压下产生了氦低温等离子体射流（296-5K）。在低于20K的气体温度下，用光学发射光谱清晰地观察到氦准分子He2。
Plasma with a gas temperature below room temperature is not yet fully understood although it is expected to be an attractive tool for applications to material processing. In the present work, gas-temperature-dependent generation of a cryoplasma jet was studied. So far, we have generated a helium cryoplasma jet (296–5K) under atmospheric pressure. At gas temperatures below 20K, the helium excimer, He2, was observed clearly from by optical emission spectroscopy.
