Abstract:
The Main Injector tune vs momentum error was measured, with trim octupole at 0, -10, and +10 Amps. These data sets were compared to the I90 simulation results. Analysis implied that the residual machine octupole content is about 30% stronger than expected, and that the trim octupole magnet strength is consistent with result reported on TM-1412.
