| 1 | GANIL有机金属离子束流的现状报告(英文)显示文摘Previous experiments with organo-metallic compounds like ferrocene,nickelocene and magnesocene showed that a pure spectrum must be obtained on the residual gas mass analyser before running successfully on the ion source.In collaboration with the chemistry department of the University of Caen,LCMT-ENSI Caen,the synthesis of these metallocene compounds has been studied to provide enriched isotopic compounds to GANIL’s users.The chemical transformation yields were 90%,80% and 43%,respectively.Vanadocene, chromocene,colbatocene and ruthenocene compounds have first been studied with a gas mass analyser and then successfully tested on the ECR 4M ion source at GANIL.Some 15eμA of 51V11+,20eμA of 52Cr11+, 22eμA of 59Co11+,and 17eμA of 102Ru11+ were achieved.The comparison between the results obtained on the gas mass analyser and the ion beams provided by the source has allowed us to validate this method of determining whether or not an organo-metallic compound could be a candidate for running on our ECR ion source.As the ECR ion sources are tuned and used alternately on the GANIL injectors,the available time for the tests is rare,so this method could be an alternative for the validation of new compounds. | P.Lehérissier C.Barué C.Canet M.Dubois M.Dupuis J.L.Flambard P.A.Jaffres P.Jardin G.Gaubert N.Lecesne F.Lemagnen R.Leroy J.Y.Pacquet | 2007 | Chinese Physics C2007，31，S1： | 0 |
| 2 | 用于产生放射性离子束ECR离子源(英文)显示文摘ECRIS’s dedicated to radioactive ion production must be as efficient as those used for production of stable elements,but in addition they are subject to more specific constraints such as radiation hardness, short atom-to-ion transformation time,beam purity and low cost.Up to now,different target/ion-source systems(TISSs)have been designed,using singly-charged ECRISs,multi-charged ion sources or an association of singly-to-multi-charged ECRISs.The main goals,constraints and advantages of different existing ECR setups will be compared before a more detailed description is given of the one designed for the SPIRALⅡproject and its future improvements. | P.Jardin C.Canet J.C.Cornell M.Dupuis C.Eleon J.L.Flambard G.Gaubert N.Lecesne P.Leherissier F.Lemagnen R.Leroy J.Y.Pacquet M.G.Saint Laurent A.C.C.Villari | 2007 | Chinese Physics C2007，31，S1： | 0 |
