Abstract
High Voltage Engineering has developed a high-current, light-ion 3.5 MV single-ended accelerator system to meet the stringent requirements on beam intensity and stability of the LUNA-MV project at Laboratori Nazionali del Gran Sasso (LNGS), L’Aquila, Italy. The accelerator has an all permanent magnet, 10 GHz ECR ion source to deliver intense beams of H (∼1 mA), He and C. The machine ensures energy stability below 10−5, terminal voltage ripple of 1.5 × 10−5 and uninterrupted operations time greater than 24 h as requested by LNGS. Various changes to the standard in-line Singletron accelerator were needed to satisfy these requirements. In this paper, we highlight design details about the accelerator and ECR source and present early performance results.
