Developments of Ion Source Complex for Highly Intense Beam at Rcnp
نویسندگان
چکیده
Several developments of Ion Source Complex at RCNP have been carried for the purpose of beam quality improvement. For 18 GHz superconducting (SC)-ECR which produces highly charged heavy ions, the new extraction system to increase the beam current has been developed and the heavy ion current has been improved. Studied for relation between this extraction and beam emittance and transmission also has been done, and it is found that there are some aperture limitations and the beam transport line should be modified to obtain more ions. Highly intense proton (HIP)-ECR the 2.45GHz permanent magnet ECR which provides highly intense proton beam has also been developed for further beam brightness improvement. Some modifications have been done and the proton beam quality also has been improved.
