Abstract

We have constructed and operated a set of two parallel plate, segmented ionization chambers, to monitor the secondary charged particle flux in the narrow band neutrino beam at the AGS. These chambers were operated successfully in a high instantaneous flux (∼5 × 10¹⁴cm⁻²s⁻¹) environment, with linear response to beam intensity. They have been used to monitor the targeting of the primary proton beam, and provide measurements of the secondary beam profile as well as the absolute beam intensity in the tunnel.
