| 英文摘要 | An advanced superconducting ECR ion source named as SECRAL was successfully built to produce intense beams of highly charged ions for HIRFL in Lanzhou. A unique feature of SECRAL is that the three axial solenoid coils are located inside of the sextupole bore in order to reduce the interaction forces between the sextupole coils and the solenoid coils. For 28 GHz operation, the magnet assembly can produce peak mirror fields on axis 3.6 Tesla at injection, 2.2 Tesla at extraction and a radial sextupole field of 2.0 Tesla at plasma chamber wall. During the commissioning phase at 18 GHz with a stainless steel chamber, tests with various gases and some metals have been conducted with microwave power less than 3.5 kW by two 18GHz rf generators. Record beam intensities of some highly charged ions have been produced, for instance, 810eμA of O7+, 505eμA of Xe20+, 306 eμA of Xe27+and so on. Dependences of the rf power, the magnetic field configuration on the ion source performance and bremsstrahlung spectra have been studied experimentally. Beam emittance from SECRAL was measured and preliminary results are given. SECRAL has been put into operation to provide highly charged heavy ion beams for HIRFL cyclotrons since May 2007. Operation status is presented. |
