Abstract :
The leading cause of the delay in the successful completion of the Tevatron Collider bunched beam stochastic cooling project was the existence of large coherent longitudinal spectral lines at harmonics of the revolution frequency (47.7 kHz) in the frequency range of 4-8 GHz. The preamplifiers of the cooling system would saturate, distorting the betatron Schottky signals to the extent that they were not suitable for stochastic cooling. The results of extensive measurement of these unexpected spectral lines are described and analyzed in this paper
