Tandem Beamline Isolation (Fast Valve) System

Introduction

The Tandem Beamline Isolation System, historically referred to as the Fast Valve System, is now a PLC controlled vacuum valve interlock system. It is designed to quickly respond to vacuum failures by isolating the accelerator beamline sections and preventing the failure from propagating further. This system also interlocks with the Pelletron to shut down operation when vacuum faults are detected in the vacuum proximal to the accelerator tubes. Each of the six valves controlled has a corresponding valve control panel (VCP) which allows the valve to be configured for operation and/or maintenance activities. All user operation occurs through these valve control panels.
