TI - Upgrade of the Beam Profile Monitoring System in the Injection Beam Line of COSY J2 - Proc. of International Beam Instrumentation Conference (IBIC2015), Melbourne, Australia, 13-17 September 2015 AB - The cyclotron Julic is used as an injector for the COSY synchrotron and storage ring of 183 m circumference. The 95 m long injection beam line (IBL) transports polarized and unpolarized H-/D- ions which are injected into the ring via multi-turn stripping injection. 8 profile monitoring stations are installed in the IBL. Each station contains two harps having 39 wires at 1mm spacing. Each harp is read out by a multichannel pico-amperemeter electronics designed by iThemba LABS, South Africa, delivering profile data to the COSY control system. The technical details of the upgrade and recent beam profile measurements are presented.
