Abstract :
The proposed K500-K1200 cyclotron coupling project calls for a redesign of both the inflector and central region of the K500. An increased injection voltage will be needed to reduce space charge effects in the higher intensity beam. In order to obtain stripping injection matching with the K1200, the K500 will operate in the second harmonic RF mode. To meet the requirements of this higher energy beam (and new RF mode) a new spiral inflector and central region geometry were designed. Results of beam orbit calculations and experimental data concerning phase selection and central region acceptance will be presented
