| MOZZO04 | New Metallic Stable Ion Beams for GANIL | 54 |
|
||
| GANIL has been producing many stable beams for nearly 40 years. Constant progress has been made in terms of intensity, stability and reliability. The intensity for some stable metallic beams now exceeds or approaches the pµA level at an energy up to 95 MeV/u: 1.14 pµA for 36S (65% enriched) at 77 MeV/u, 0.35 pµA for 58Ni (63%) at 74 MeV/u. The presentation highlights recent results obtained for 28Si, 184W and 130Te using the GANIL ‘s LCO (Large Capacity Oven) on the ECR4 ion source. To produce the tungsten beam, two injection methods were compared. For the first one, we evaporated some tungsten trioxide (WO3) with GANIL ‘s LCO. For the second one, the injection in the plasma chamber was made by using MIVOC (Metallic Ions from VOlatile compounds) with a tungsten hexacarbonyl (W(CO)6) compound. It was the first time that we used metal carbonyl compounds and the result is promising. All the tests have been qualified to obtain the level of intensity and beam stability. Theses good results led us to propose them for Physics experiments. | ||

| WEZZO01 | Role of the 1+ Beam Optics Upstream the SPIRAL1 Charge Breeder | 146 |
|
||
|
The SPIRAL1 charge breeder (SP1CB) is under opera-tion. Radioactive ion beam (RIB) has already been deliv-ered [1] to Physicist for experiments. Charge breeding efficiencies demonstrated high performances for stable ion beams than RIB’s. The beam optics, prior to the injection of the 1+ ions into the SP1CB, is of prime im-portance [2] for obtaining such high efficiencies. Moreo-ver, the intensities of the RIB’s are so low, and indeed difficult to tune the SP1CB. A stable beam having a close B’ is required to find out the set of optic parameters preceding the tuning of the RIB. Hence, it has been de-cided to focus our effort on the control of 1+ beam optics leading to high charge breeding efficiencies whatever the 1+ mass, energy and Target Ion Source System (TISS) used. This contribution will show the strategy undertaken to overcome that problem and the results obtained.
