This paper describes a ten-liters fiberglass reinforced plastic ( FRP ) liquid-helium dewar, which is prepared for SQUID. The inter container is made of DB-1 cryogenic FRP, and the outer case of this dewar is made of epoxy-polyamide FRP. The dewar structure is non - magnetism. It's equibrium evaporation rate is 0.73 liters per day (21.44mW ) . After liquid-helium test we find that helium permeability is an important factor for FRP liquid-helium dewar.

本文介绍了用于SQUID测量的10升玻璃钢液氦杜瓦,内胆用DB—1低温玻璃钢制作,杜瓦外壳采用环氧—聚酰胺玻璃钢制造。采用无磁的结构型式。平衡时每天蒸发液氦0.73升(21.44mW)。液氦试验发现:氦气渗透是影响玻璃钢液氦杜瓦性能的重要因素,应予以重视。

It is convenient to introduce high-purity helium gas into ultra-high vacuum with the character of diffusion. By this way, it is not only cooling the velocity of ions, reducing the second-order Doppler frequency standard, consequently improving the stability of microwave frequency standard, but also achieving longer storage time of ions in the trap. Here, we present the experiment parameters, regularity of helium gas diffusion. It also shows the diffusion effect to the vacuum and has achieved temperature precisely...

利用氦的渗透性质,向超高真空系统中充入高纯度氦缓冲气体,可以降低离子阱中囚禁离子的运动速度,减小二级多普勒频移,增加离子的存储时间,提高线型离子阱微波频标的稳定度。实验上得到了氦气渗透的实验参数、特性以及对系统真空度的影响、实现了用温度调节精确的控制充入氦气的分压强。
