MOCO-A01	Recent Results and Operation at 18 GHz with SECRAL	1
	H. W. Zhao, L. T. Sun IMP, Lanzhou
	An advanced superconducting ECR ion source SECRAL with 18GHz has been put into operation to provide highly charged heavy ion beams for HIRFL (Heavy Ion Research Facility in Lanzhou) cyclotron since May 2007. The paper will give an overview of recent operation status and test results for enhancing performance of the SECRAL ECR ion source. Detailed experimental results with an aluminium chamber, 14+18 GHz double frequency heating, emittance measurements, and bremsstrahlung measurements will be presented. Finally some upgrading program for SECRAL will be reported.

MOCO-B05	The High Charge State All-Permanent Magnet ECRIS Operated on 320 kV HV Platform	23
	L. T. Sun IMP, Lanzhou
	An all-permanent magnet ECR ion source named LAPECR2 (Lanzhou All-permanent magnet ECR ion source No. 2) has been built and tested at IMP. This ion source is designed and operated to produce intense ion beams of both low charge states (such as H+, He2+, Xe3+) and high charge states (such as Ar14+, Xe30+) for the 320 kV high voltage (HV) platform at IMP. Many good results have been obtained on LAPECR2, such as 1emA O6+, 130 eμA O7+, 166 eμA Ar11+, 0.33eμA Ar17+, 85 eμA Xe20+, 24eμA Xe27+, 2eμA Xe31+. This ion source was designed to fulfill the various requirements of all of the experimental terminals, such as the delivery of metallic ion beams. A high temperature micro-oven has been fabricated and installed on the source to produce stable metal vapor. This HV platform has been successfully biased to 395 kV without ion beam. And ion beams with the energy up to 150 keV/q have already been delivered to the successive experimental terminals. After a brief introduction of the source LAPECR2, the operation status on the HV platform is discussed. The typical performance of the source of both gaseous and some metallic ion beams will be given in this paper.
