MOOMMH03 | First Results At 24 GHz With The Superconducting Source For Ions (SuSI) | ion, ion-source, plasma, operation | 1 |
|
|||
The superconducting ECR ion source SuSI at Michigan State University was designed to operate primarily at 18GHz and has demonstrated very good performance at this frequency especially when coupling two klystrons to the plasma [1]. Following a period of training, SuSI has been able to reach the magnetic field needed for operation in the high-B mode at 24 GHz. SuSI has several interesting features. First the axial magnetic profile is defined using 6 solenoids which provide some flexibility to adjust parameters such as field gradient at the resonance, Bminimum or plasma length. Second with a diameter of only 101mm, SuSI plasma chamber has a nominal volume of about 3.5 l. Therefore, power density in excess of 2kW/l could be reach and lead potentially to new insight on the maximum performance achievable with an ECR. In January 2014, a 10 kW 24 GHz Gyrotron obtained from the Russian company GYCOM was commissioned at MSU on a dummy load and then connected to SuSI. We report here on the first measurements done with SuSI at 24 GHz.

MOPPH002 | Production Of Metallic Stable Ion Beams For GANIL And SPIRAL2 | ion, ion-source, ECR, experiment | 45 |
|
|||
GANIL has been producing many stable beams for nearly 30 years. Constant progress have been obtained in terms of intensity, stability and reliability. The presentation highlights recent results obtained for 50Ti beam production from an organo-metallic compound using the MIVOC (Metallic Ions from Volatile Compounds) method with the ECR4 ion source. The synthesis of this compound has been studied and realized by the IPHC-Strasbourg team from isotopically enriched titanium metal. Preliminary tests using natural titanocene were performed to validate the production method in terms of beam intensity, stability and reliability. Results obtained allowed us to program a physics experiment in September 2013. A 50Ti10+ beam was maintained stable for 300 h with a mean intensity of 20 μA. Q/A=1/3 ion source of SPIRAL 2 facility, whom commissioning will be led by end of 2014, is Phoenix V2 ion source which has been developed by LPSC-Grenoble. Results obtained for nickel (58Ni19+) and calcium (40Ca16+) in collaboration with LPSC Grenoble will be presented in this report.

MOPPH016 | Modernization of the mVINIS Ion Source | ion, plasma, ion-source, extraction | 68 |
|
|||
The mVINIS ECR ion source was designed and constructed jointly by the team of specialists from FLNR JINR, Dubna and Laboratory of Physics, Vinča Institute, Belgrade. It was commissioned and put in operation in 1998. From that time it was widely used in the field of modification of materials by different kinds of multiply charged ions. Recently we decided to modernize mVINIS in order to improve its operation reliability. Our main goal was to refurbish its major components (vacuum pumps, microwave generator, control system etc.). Besides, we decided to enhance basic construction of the ECR ion source in order to improve the production of multiply charged ion beams from gaseous and solid elements. We changed the shape of the plasma chamber and consequently reconstructed the magnetic structure. Also we improved the construction of the injection chamber. All these improvements resulted in substantial increase of ion beam intensities, especially in the case of high charge state ions. | |||
WEOMMH03 | Development of the Magnetic System for New DECRIS-PM Ion Source | ion, permanent-magnet, extraction, cyclotron | 111 |
|
|||
Super-heavy-element factory is under development at the Flerov Laboratory for Nuclear Reactions, JINR, Dubna. The factory will include DC-280 cyclotron, which will be equipped with two 100 kV high voltage platforms. All-permanent magnet ECRIS will be installed on one of the platforms. The request for the source is a production of medium mass ions with A/q=4-7.5 such as 48Ca8+. Results of the detailed design of a magnetic structure for DECRIS-PM will be presented. | |||

WEOBMH01 | Experimental Activities with the LPSC Charge Breeder in the European Context | ion, plasma, ECR, ECRIS | 120 |
|
|||
Funding: NuPNET project (Enhanced Multi-Ionization of short-Lived Isotopes at EURISOL) One of the Work Packages of the "Enhanced Multi-Ionization of short-Lived Isotopes at EURISOL" NuPNET project focuses on the ECR charge breeding. The LPSC charge breeder is used for experimental studies in order to better understand the fundamental processes involved in the 1+ beam capture by a 14 GHz ECR plasma. Some improvements, like symmetrisation of the magnetic field at the injection side and higher pumping speed, have been carried out on the PHOENIX charge breeder. The impact of these modifications on the efficiencies and charge breeding times are presented. In the same time, the new LPSC 1+ source developments performed in order to ease the efficiency measurements with various elements are presented. |
