TI - Laser Ablation Ion Source for Highly Charge-State Ion Beams J2 - Proc. of Heavy Ion Accelerator Technology Conference (HIAT2015), Yokohama, Japan, 7-11 September 2015 AB - Acceleration experiments of gaseous heavy ions delivered from the ECR ion source are in progress in the KEK Digital Accelerator(KEK-DA)*. KEK Laser ablation ion source (KEK-LAIS) has been developed to generate highly ionized metal ions and fully ionized carbon ions since 2012**. Basic parameters such as a charge-state spectrum, momentum spectrum, spatial distribution of the plasma current, extracted ion beam current, and emittance have been obtained. Since diffusion of a laser ablated plasma is known to be controlled by magnetic guiding fields***, these parameters are measured as a function of solenoid guide fields and its length. Meanwhile, 10Hz continuous ablation plasma experiment, which is a crucial trial for accelerator applications, will be carried out with a newly developed moving target. The stability in accelerator beam parameters such as the pulse width and intensity is confirmed. At the conference, the extraction of heavy ion beams from the LAIS and post acceleration will be also discussed, including beam optics through the low energy beam transport line to the KEK-DA.
