Description

The Spallation Neutron Source (SNS) is implementing camera-based systems to enhance the reliability of high-power RF vacuum windows in its Drift Tube Linac (DTL) and Coupled Cavity Linac (CCL) sections. In the DTL, a high-speed camera will detect electron glow discharges sometimes associated with multipacting, a critical issue leading to window damage. This effort is part of a broader project to address multipacting and improve overall window performance. For both the DTL and CCL sections, infrared cameras will monitor ceramic window temperatures. A recent cooling system failure resulted in excessive temperatures and a CCL window failure, highlighting the need for this system. Both camera-based systems are under development, with initial results showing promise for improved window operation and protection.
