2X scaled Penning source developments
Abstract
To meet the full 2 ms 50 Hz 60 mA beam requirements for the Front End Test Stand (FETS) at the Rutherford Appleton Laboratory (RAL), a new cesiated Penning Surface Plasma Source (SPS) has been developed with a larger plasma volume with 2X (double) the linear dimensions of the standard ISIS source. This paper outlines the development work through preliminary tests and two prototypes. The latest results have demonstrated that operation at full duty cycle is possible but with a `noisy' beam. A `clean' beam was obtained at lower duty cycles and high cesium flux.
