Abstract :
Transverse Schottky noise and coherent betatron modulation of the bunched beam revolution harmonics in the Tevatron are continuously monitored by a sensitive receiver. The electronics rely upon low-noise amplifiers, narrowband filters, and spectrally pure oscillators to obtain a minimum detectable signal of -160 dBm. Dynamic range is 80 dB. Separate baseband proton and antiproton signals are continuously analyzed in the Main Control Room
