Design of a multi-harmonic buncher for lince
Continuous beams delivered by the LINCE [1] ECR ions
source will be bunched by a multi-harmonic buncher in order
to be injected into an RFQ. Its numerical design is reported
along with electric field maps and beam dynamics studies
carried out with the codes TRACK [2] and GPT [3]. First
experiments with multi-harmonic bunchers were carried out
in 1970s at Argonne National Lab. (ANL) [4] and it is used
in the design of modern accelerator facilities e.g FRIB and

Elastic scattering of 8He + 208Pb at 22 MeV
The dynamics of 8He around the Coulomb barrier is investigated by measuring the energy and angular distribution of the elastic 8He and the 6He and 4He fragment yields in the collision process with a 208Pb target. The experiment was carried out at SPIRAL/GANIL in October 2010. The experimental results will provide information about the relevant reaction mechanisms and the validity of the optical model (OM) when applied to exotic nuclei. In this paper, details of the experimental setup and preliminary results on the elastic scattering for the collision at 22 MeV are presented
