+ This is really an old magnet and has to be replaced. It is easy to use, |
+ with a small enough sample (<25 mm diameter) at a temperature of 4.2 K. |
+ ''Everthing else is a pain!'' With higher temperatures the |
+ thermal gradient is huge (can be improved when pumping the intermediate space). |
+ Lower temperatures (1.7 K) are possible, but with a very high LHe consumption. |
