Description

The Spallation Neutron Source (SNS) at Oak Ridge National Lab (ORNL) has built and commissioned an independent Cryogenic Test Facility (CTF) in part to support 4.5 K operation of a Horizontal Test Apparatus (HTA) vessel in the Radiofrequency Test Facility (RFTF) test cave. The HTA provides the functionality for testing a single dressed SNS medium or high beta Superconducting Radiofrequency (SCRF) cavity. The vessel’s capability to provide for in-situ plasma processing of the cavity’s inner niobium surface will be discussed. The design and commissioning of the HTA at 4.5 K will be presented as well as results from operating the HTA including cool-down, warm-up and steady state operations. Result from plasma processing a warm SCRF cavity in-between cold HTA tests will also be addressed.
