+ 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, especailly at temperatures below 20 K. For that reason, it
+ is necessary to put even single crystals into a seald sample container
+ containing He gas. Some ideas what gradients can be expected can be
+ taken from a [CTITestReport].
