N2 - An ionization profile monitor (IPM) has been designed for the Spallation Neutron Source (SNS) accumulator ring with the goal of simplifying current IPM technology to provide accurate high-intensity beam profiles. Utilizing ionized electrons produced by beam-gas ionization, the SNS IPM uses a 120 kV bias potential and uniquely designed electrode to overcome beam space charge and accelerate electrons towards a movable particle detector. A 300 G magnetic field will be used to confine the transverse electron motion, resulting in profile errors at the 7% level. With a system bandwidth of 17.5 MHz, the SNS IPM will be capable of measuring turn-by-turn beam profiles for a fully accumulated beam. This paper presents a description of the system and design.
