Ambient beam motion and its excitation by ghost lines in the Tevatron
Ambient beam motion its excitation ghost lines Tevatron
2012/2/28
Transverse betatron motion of the Tevatron proton beam is measured and analyzed. It is shown that the motion is coherent and excited by external sources of unknown origins. Observations of the time-va...
