3HE BIG BLUE

The bottom loading Big Blue is a ³He based cryostat that can reach a lower base temperature than the ³He based orange cryostats. However, this system is also more difficult to use and therefore requires the assistance of a qualified user. A tail set containing two quartz windows can be fit after loading a sample for use in a SANS experiment. This cryostat is also useful for its large sample space compared to other low temperature systems. The preparation of the system must be at least 1 week before the experiment starts. Sample environment staff should be contacted well in advance.
