Abstract :
Fermilab High Energy Physics research program for RUN-II requires rapid generation of antiprotons and high intensity protons. We had previously observed longitudinal mode mixing in the Main Ring and Tevatron at intensities desirable for the RUN-II. We incorporated high-speed digitizer (RTD-720) and (LeCroy 9384CM) to measure the time domain, and further spectral analyses were performed to measure the mode couplings. We have refined our measurement analysis in conjunction with higher digitization to pursue higher mode couplings. Data during the commissioning of the newly constructed Main Injector are compared to previously obtained data
