The improvement program for higher intensity and better quality in the Princeton University cyclotron

A new design of the second-harmonic central region for the Princeton cyclotron has been carried out. Extensive beam extraction studies based on the new design have also been performed. These studies suggest that modifications to the shape of the electrostatic deflector can lead to greater extraction efficiency. This result is consistent with the observed burn marks created by the beam in the present extraction region. Further improvements will also be introduced to increase the power dissipation that can be tolerated in the extraction septum
