Description

Content Description: E760 uses the longitudinal Schottky spectrum of the circulating beam in the Accumulator to extract the momentum spectrum: {Delta}p/p = 1/{eta}*{Delta}f/f. Hence it is required to accurately know {eta} at all energies. {eta} can be measured to about 5% by measuring the synchrotron frequency of bunched beam vs. the RF voltage and using the relation {eta} = 2{pi} f{sub s}{sup 2}{beta}{sup 2}E/H f{sub 0}{sup 2}eV. ARF3 (H = 2) was used in this case.
