The 50mm Orange Cryostat is basically a 70mm with a smaller sample well diameter and a much smaller diameter tailset. This allows the 50mm to fit into almost all the instruments. Where as a 70mm bolts directly to the top of the Huber table a 50mm mounts to the same adapter plate as a CCR. There are two 50mm's available for use at the NCNR.
