Abstract:
In the end-of-the-store study on November 17, 2002,
we excited individual pbar bunches using the Tevatron Electron Lens
(TEL) and detected the associated signals in the proton and pbar
vertical Schottky spectra, as well as their response to pbar and
proton tune changes The tune for the p-bar bunch A24 could
thus be inferred. Subsequently, the antiprotons were slowly
scraped to nearly zero intensity, in an attempt to compare the p-bar
emittances obtained by the flying wires and by the synchrotron light
monitor with those derived from the remaining beam intensity measured
as a function of collimator position.
