Abstract	The ISIS Synchrotron uses dipole magnets to steer the proton beam to maintain a fixed radius circular orbit. The beam energy is synchronised to the 50 Hz magnetic field as protons accelerate from 70 to 800 MeV before extraction. The failure of a single dipole causes several days of costly machine downtime. ISIS currently employs a simple form of manual vibration monitoring to assess magnet health before each machine cycle. In this paper we discuss a new condition monitoring scheme that utilises modern technology, to perform remote vibration monitoring and analysis in real time during beam operation. Two dipole magnets were instrumented and data were acquired across two adjacent cycles of operation. The results show the quality of data achievable from this hostile environment. Data analysis, using proven experimental methods, characterised the magnets and plotted performance over time as a proof of concept prior to a full rollout of the system.
