Fermilab Main Ring ion profile monitor system

“…The Main Injector and Recycler Ion Profile Monitors capture horizontal and vertical profiles at a once-per-turn sample rate [11], [12]. Microchannel plates are used to amplify the charge produced when the beam passes through the residual gas in the normal accelerator vacuum.…”

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.

The Booster Ion Profile Monitor (BIPM) was recently (April 1998) used in a test to study the feasibility of collecting the electrons instead of the more traditional ions. These electrons and ions are created by the ionization of the residual gas in the beam pipe by the proton beam. As a consistency check, the proton beam current is compared to the integrated area of the measured profile through the acceleration cycle. It was found necessary to include the effect of the proton beam energy upon ionization by means of the Bethe-Bloch equation in order to have satisfactory agreement.
