Chromaticity Head-Tail Application for the Tevatron
- Fermi National Accelerator Lab. (FNAL), Batavia, IL (United States)
The Chromaticity head-tail phase technique has been developed for use in the Tevatron. This method is based on the phase shift, which develops for particles of different energies within a single bunch. Since this phase shift is proportional to chromaticity, knowledge of the phase shift over a synchrotron period can allow extraction of the chromaticity. Currently the Tevatron uses a varying RF technique to measure chromaticity. So far the RF method cannot effectively measure chromaticity for coalesced proton bunches. The Head-Tail technique however seems to be capable of extracting chromaticity for coalesced protons even during acceleration. This application will greatly speed up chromaticity measurements especially during ramp and squeeze which currently require three separate ramps using uncoalesced protons.
