The limits of on-line dilution refrigerators for no-studies
- 15 Downloads
A description is given of on-line dilution refrigerators for nuclear orientation studies at ultra low temperatures (T<20mK). The experimental requirements are compared with the theoretical performance of dilution refrigerators and the latest technical designs. An analysis of existing and working machines shows that the optimum design is mainly limited by detector-sample distance, magnetic field homogeneity and maximum size of detector.
