. Spectral analysis of beam jitter in the Stanford Linear Collider (SLC) has shownthat some beam motion is confined to narrow frequency bands. Vibration analyses of linacquadrupoles using high-resolution accelerometers yield spectra having a similar footprint. Itwas found that motion at 59 Hz is driven by a pressure oscillation in the accelerator structurecooling water, while other frequencies were found to be vibrational modes of the structureitself (1). This paper presents...
