| Abstract | The High Current Experiment (HCX) is exploring the physics of intense beams with high line-charge density. Superconducting focusing quadrupoles are being developed for future magnetic transport studies at the HCX. A baseline design was selected following the testing of several pre-series models. Optimization of the baseline design led to the development of a first prototype in 2003. This magnet achieved a conductor-limited gradient of 132 T/m in a 70 mm bore without training, with measured field errors at the 0.1% level. Based on these results, both the magnet geometry and the fabrications procedures were modified to further improve the field quality. These modifications were implemented in a second prototype. In this paper, comparisons between the design harmonics and magnetic measurements performed on the new prototype will be presented and discussed. |
