“…The Booster Ionization Profile Monitor [8] (IPM) is able to extract horizontal and vertical beam profiles on a turn-by-turn basis for an entire Booster cycle. The IPM utilizes an electric field to collect ions from ionization of the residual beam gas on micro-strip counters.…”

High precision modeling of space-charge effects is essential for designing future accelerators as well as optimizing the performance of existing machines. Synergia is a highfidelity parallel beam dynamics simulation package with fully three dimensional space-charge capabilities and a higher-order optics implementation. We describe the Synergia framework, developed under the auspices of the DOE SciDAC program, and present Synergia simulations of the Fermilab Booster accelerator and comparisons with experiment. Our studies include investigation of coherent and incoherent tune shifts and halo formation.

“…In order to study beam halo generation we need to use a detector which provides non-destructive beam shape measurement on a turn-by-turn basis. The Booster Ionization Profile Monitor (IPM) [9] is the only such device in the Booster, capable of measuring beam profiles with a time resolution of a single turn (2.2 micro seconds at injection) at all times in the cycle. The IPM measures profiles using ions produced by the interaction of the beam with the imperfect vacuum of the machine.…”

During the past year, the Fermilab Booster has been pushed to record intensities in order to satisfy the needs of the Tevatron collider and neutrino programs. This high intensity makes the study of space-charge effects and halo formation highly relevant to optimizing Booster performance. We present measurements of beam width evolution, halo formation, and coherent tune shifts, emphasizing the experimental techniques used and the calibration of the measuring devices. We also use simulations utilizing the 3D space-charge code Synergia to study the physical origins of these effects.

“…The FNAL Booster has two measuring devices capable of measuring of beam widths with such resolution: the Ion Profile Monitor detector (IPM) [4], which utilizes the ions from ionization of the residual gas by the proton beam to measure transverse beam profiles, and the Resistive Wall Monitor (RWM) device, which utilizes the induced current on the beam pipe by the particle beam, to measure the longitudinal beam profile. Since the response of the IPM depends on the charge of the beam, and since the goal of the experimental program is to use this detector for a quantitative study of space charge effects, we installed a third measuring device, the "flying beam" wire, in order to check and calibrate the performance of the IPM.…”
