Abstract:
Because of the large emittance and momentum spread of injection beam, the edge field of magnets will affect beam optic property during injection into the experimental ring of HIRFL-CSR (Heavy ion Research Facility in Lanzhou-Cooling Storage Ring). The influence of edge field is probed in this paper by numeric tracking of particles through it. The influence is reduced to tolerable range by modifying injection central orbit and field distribution of the magnet.
