Difference between version 21 and version 1:
At line 0 added 8 lines.
+ Close cycle refrigerators are really easy to use, as one does not need
+ to deal with cryogens. However, all our present system have one drawback:
+ The sample is mounted in vacuum, which leads to some uncertainity in the
+ temperature, especially at temperatures below 20 K. For that reason, it
+ is necessary to put even single crystals into a sealed sample container
+ containing He gas. Some ideas what gradients can be expected can be
+ taken from a [CTI Test Report].
