Abstract
The Spallation Neutron Source (SNS) Linear Accelerator (Linac) delivers a high power proton beam (>1 MW) for neutron production with high neutron availability (>90%). For beam acceleration, the linac has both normal and superconducting RF sections, with the Superconducting Linac (SCL) portion providing the majority of beam acceleration (81 of 96 RF cavities are superconducting). Operationally, the goal is to achieve the highest possible beam energy by maximizing SCL cavity RF gradients, but not at the expense of cavity reliability [1, 2]. One mechanism that has negatively impacted both SCL cavity peak RF gradients and reliability is beam lost into the SCL due to malfunctions of upstream components. Understanding the sources and impact of errant beam on SCL cavity performance will be discussed.
