该极化器系统包括冷却室,该冷却室在其中具有用于将物质(22)极化的低温致冷剂(26)。
The polarizer system includes a cooling chamber having a cryogenic refrigerant (26) therein for use in polarizing a substance (22).
由于是冷凝低温式机器(冷凝泵在密闭腔内能产生高真空环境,带电粒子在高真空中才能生存:译者注),运行时候温度极低,LHC要回到常温大概要一个月,并且致冷过程也要花费一个月。
Being a cryogenic machine operating at very low temperature, the LHC takes about a month to bring up to room temperature and another month to cool down.
