Beam diagnostic systems in the IUCF Cooler and Cyclotron

Beam diagnostics for the Indiana University Cyclotron Facility (IUCF) Cooler synchrotron which have been recently developed include a beam phase feedback system to damp synchrotron oscillations induced by the RF system and a transverse phase space tracking system to measure the betatron fractional tunes and to investigate nonlinear beam dynamics. New cyclotron diagnostic systems include a new beam timing system which has been improved in sensitivity by over a factor of 10, a cyclotron beam turns counting system, and an electrostatic quadrupole magnet modulator to vary beam intensity in synchronization with the beam switching magnet. The design, performance, and problems associated with these systems are discussed.<
