Technical Information – Beam intensity
SRC
For those who plan to propose an SRC-use experiment in the next PAC, please take a primary beam from the table, and the “expected" current also given in the table for its current. The 48Ca beam will be unavailable until the 48Ca ion source material becomes ready. If you plan to use an unavailable beam which is denoted by “N/A” or not listed in the table, it is essentially important to make a contact with the RNC Accelerator Group well in advance before the proposal submission.

RRC
RRCのビームはAVF又はRILAC入射により提供されます。Neより重いビームをAVF入射で利用したい場合、東大 CNSと共同研究によりビーム開発する必要があります。実験提案の際は、事前に CNS の担当者とコンタクトを取るようお願いします。
Beams from RRC are delivered in the schemes of AVF or RILAC injection. If you plan to use RRC beams heavier than Ne isotopes in the AVF-injection scheme, they need to be developed in collaboration with CNS, University of Tokyo. It is essentially important to contact User Support Office or CNS before you submit a proposal.
