Title Understanding Extraction and Beam Transport in the ISIS H− Penning Surface Plasma Ion Source
Abstract The ISIS particle accelerator H− Penning surface plasma source has been developed to produce beam currents up to 70 mA and pulse lengths up to 1.5 ms at 50 Hz. This paper details the investigation into beam extraction and beam transport in an attempt to understand the beam emittance and to try to improve the emittance. A scintillator profile measurement technique has been developed to assess the performance of different plasma electrode apertures, extraction electrode geometries, and post extraction acceleration configurations. This work shows that the present extraction, beam transport, and post acceleration system are suboptimal and further work is required to improve it.
