Abstract :
Four ionization beam profile monitors (IPMs) have been installed in RHIC to measure vertical and horizontal profiles in the two rings. Each IPM collects and measures the distribution of electrons in the beamline resulting from residual gas ionization during bunch passage. The electrons are swept transversely from the beamline and collected on strip anodes oriented parallel to the beam axis. At each bunch passage the charge pulses are amplified, integrated, and digitized. The system is designed to measure single-bunch profiles with up to 120 bunches in each ring
