The Spallation Neutron Source (SNS) is building Superconducting Radio Frequency (SRF) processing and testing facilities to support the reliability and sustainability goals of the enterprise. Some of the testing facilities require cryogenic helium at both 4K and 2K. Currently, 4K helium is supplied to the test cave from the Central Helium Liquefier (CHL) that also services the linear accelerator. As more facilities become available and testing is more frequent, it is essential to separate testing in this facility from the operation of the accelerator. This paper describes the cryogenic system under development at SNS to supply SRF testing needs. The initial phase of the project was to supply 4K helium to a Vertical Test Area (VTA) and the test cave which is capable of housing either the Horizontal Test Apparatus (HTA) or a cryomodule. It was desired to make the system as flexible as possible to meet the needs at SNS. The scope of the initial phase of this project has been expanded. First, the system will be outfitted with warm pumping capability to produce 2K helium in the testing systems. Second, a liquid fill station will be incorporated to fill portable helium Dewars.
