Popis: A novel sub-Kelvin refrigeration cycle is introduced in this work. The magnetically driven superfluid pulse tube refrigerator (MSPTR) could provide cooling at temperatures below 200 mK while rejecting heat at 1.6 K and contains no moving mechanical parts. The MSPTR cycle has an advantage over other types of sub-Kelvin cooling in that it can provide distributed cooling. Additionally the MSPTR unlike the dilution refrigerator will be able to function in microgravity without any modification. This work includes a description of the MSPTR cycle and a summary of preliminary design calculations including results used to size components and predict cooling performance.
