Abstract
Four ionization beam profile monitors (IPM´s) are 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 IPM´s performed well during the 1999 commissioning run and early in the 2000 run. However as the bunch intensity increased there was a beam-induced ringing that increased in amplitude until it saturated the amplifiers and made the IPM´s unusable. Near the end of the run the cause of the ringing was found and one IPM was fixed. At the start of the 2001 run all four IPM have EMI shielding installed
