“…They are also used to obtain the 95% longitudinal beam emittance and diagnose instabilities. In the Tevatron, the signal is used by the Sampled Bunch Display [4][5][6][7] as well as the Fast Bunch Integrator systems [8][9][10] to measure and track the intensity of individual bunches. Recently, they have been used to monitor luminosity for colliding beams operation.…”

Resistive Wall Current Monitors (RWCM) were designed and built for the Fermilab Tevatron (Tev) project. These devices measure longitudinal beam current from 3 KHz to 6 GHz with 1.34 ohm gap impedance. There are two RWCM's installed a few feet apart in the Tevatron, upstream RWCM is used for general purpose use, downstream RWCM is dedicated for longitudinal parameters of coalesced beam bunches and bunch intensities. The design provides a calibration or test port for injecting test signals. Microwave absorber material is used to reduce interference from spurious electromagnetic waves traveling inside the beam pipe. This paper will do an overview how the RWCM was designed and its test results.

“…This system measures the intensity of both the original batch and the final individual bunch by using wide and narrow gated integrators [14]. A comparison of these two measurements provides the capture efficiency and indicates how much beam remained in adjacent RF buckets.…”

An overview of the instrumentation installed in the Fermilab Main Injector is presented. Efficiency, beam loss, average intensity, bunch intensity, position, betatron and synchrotron oscillation frequency, as well as transverse and longitudinal profiles are measured. Systems such as the Beamline Tuner and the Ionization Profile Monitor track changes through the accelerating cycle and analyze their rate of change.
