Description

The Oscillating Arm Wire Monitor (OAWM) is a new type of wire scanner designed to operate at maximum speeds exceeding 4 m/s, which are required to perform scans of high-intensity beams. This paper summarizes the comprehensive tests and measurements carried out on the OAWM, focusing on both its operational endurance and its underlying mechanical dynamics. We report on extensive endurance tests, comprising thousands of scans, to validate long-term system reliability in high-intensity beam environments. In addition, we analyze the vibrations of the fork at various speeds and investigate the corresponding damping behaviour. Fast operation tests were successfully conducted in a primary beamline (e.g., the 870 keV line) to verify that signal quality is maintained under realistic operating conditions. The results demonstrate that reduced inertia and optimized gear ratios enable faster, more stable, and highly reliable beam diagnostics.
