Abstract
The Spallation Neutron Source (SNS) Superconducting Linac (SCL) has been providing a main acceleration in two different accelerating sections with 33 medium beta and 48 high beta superconducting radio-frequency (SRF) 6-cell cavities. The use of superconducting elliptical cavities for particles whose velocity are less than speed of light (beta<1), make this accelerator a very important milestone for learning operating conditions of this type of cavities. Since the SNS SCL is the first large-scale high energy pulsed-superconducting proton linac that provides high beam power utilizing H- beams, many aspects of its performance were unknown and unpredictable. A large amount of data has been collected on the pulsed behavior of cavities and cryomodules at various repetition rates and at various temperatures. This experience will be of great value in determining future optimizations of SNS as well in guiding in the design and operation of future pulsed superconducting linacs. This paper describes the details of the RF properties, performances, path-forward for the SNS power ramp-up goal, and upgrade path of the SNS superconducting linac.
