Abstract:
Though we have had evidence of various sorts since last December of a rather strong coupling between radial and vertical betatron oscillations in the main ring, the present experiment represents the first quantitative examination of the phenomena. For a number of reasons, the experiment was .carried out at high energy. Near injection energy, betatron oscillation studies in the main ring have always defied detailed interpretation; indeed, early in this work an attempt to obtain understandable results at injection was unsuccessful. At high energy, one may hope that linear coupling effects can be isolated, which, when removed, may facilitate analysis of the low-energy region, as well as reduce the vertical emittance of the slow extracted beam.
