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. 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.

¶ Some intensities are limited by shielding requirements

Please also refer our tentative two-year plan of primary beams for BigRIPS-based experiments:

Autumn –Winter 2012 : 238U, 124Xe, and light ions (AVF-injection)
Spring 2013 : 238U, 78Kr, (48Ca)
Autumn –Winter 2013 : (open)

 

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 with User Support Office or CNS before you submit a proposal.
