Its He-evaporation rate is less than 200ml per hour. Eight copper-constantan thermocouples are set between the inner and outer walls and give the data of the temperature gradients over the shields.

由我们研制的几种杜瓦瓶表明,将多层绝热结构应用于低温液氦实验杜瓦瓶,代替液氮保护,可以得到良好的效果. 我们研制的口径为φ5120mm、φ150mm、φ200mm,内胆容积分别为10升、27升、38升,用铝箔和玻璃纤维纸作多层绝热结构的液氦实验杜瓦瓶液氦平均蒸发率分别为100毫升/小时、120毫升/小时、180毫升/小时,适于低温实验室推广使用. 另一个口径为φ120mm,内胆容积为10升,用喷铝涤纶薄膜和两个铜屏作多层绝热结构的液氦实验杜瓦瓶已使用六年,液氦蒸发率小于200毫升/小时.在该杜瓦瓶夹层中放有八个铜-康铜热偶温度计,提供了有关屏温分布的参考数据.

The samples can be changed at any time when the magnet is in operating...

This system consists of five parts: a 10T superconducting magnet, a 150 A power supply, a metallic inner dewar, a 80 1 liquid helium outer dewar and some other auxiliaries including the thermal shield, the magnet support, current leads, etc. The inner dewar which is placed in the bore-hole of the magnet provides a φ = 30 mm variable-temperature space from 4.2 K to 400 K and the superconducting magnetic field can be adjusted from 0 to 10 T. The samples can be changed at any time when the magnet is in operating state. The construction of the outer dewar is a gas-cooling multi-shield insulation without liquid nitrogen protection. The loss rate of the liquid helium is 0.21 liter per hour. At 10T field strengh, when the temperature in the inner dewar is at 70 K, the loss rate is in the range of 1.3-1.6 liters per hour.

该装置由11T超导强磁体;ф_内=30mm室温孔径的金属内杜瓦瓶;80升液氦金属外杜瓦瓶;JWL-150A超导磁体电源以及防辐射屏、吊杆、引线等五部分构成。金属内杜瓦瓶直接插在磁体内径中,其实验空间与外界相通,它可在4.2—400K之间变温,在0—10T之间改变磁场强度,也可随时更换测试样品。金属外杜瓦瓶采用气冷多屏绝热的结构。它自身的蒸发率为0.21升/小时。在内杜瓦瓶温度~70K、场强为10T时,液氦蒸发率为1.3—1.6升/小时之间。

The Dewar with multishield thermal insulation structure has been developed. The inner vessel is suspended with neck tube and there are no other thermal conducting channels.The suspension structure is sealed with the bellows and supported by a movable spherical bezeJ.Thus the previous drawbacks of outbreak due to the derect welding and shock force are avoided.
