+ The small furnace is based on the "hot-finger" principle. It is cooled |
+ by radiation only, and there are there is only one radiation shield, |
+ mountable on the hot finger (inner diameter 28 mm, inner length 80 mm). |
+ This leads to a relatively large temperature gradient on the sample. |
+ But as there are three thermocouples (one on the hot finger and two freely mountable), one |
+ can at least get an idea about the gradient. |
