摘要
兴建中的放射性次级束流线 ,是兰州重离子冷却储存环中连接主环和实验环的束运线的主要部分 .描述它的结构、离子光学 ,以及二。
A new radioactive ion beam line designed to work at higher energy equivalent up to a magnetic rigidity of 10.64Tm is going to be constructed at Lanzhou. It is to connect the main ring and the experiment ring of the HIRFL CSR complex. The separator is mirror symmetrically configured both in geometry and magnet strength, achieving a point point and parallel parallel image at its intermediate focal plane with maximum spatial dispersion. Achromatism is automatically realized at the final focal plane. The total length is about 26 meters. Its resolution power of magnetic rigidity is 1200 at ±1% momentum deviation and ±25mrad divergence simultaneously. With sextupole ?and octupole ?magnets carefully positioned and powered, second and third order aberrations are corrected to a large extent. The magnet design has already fulfilled.
