Description
After the development in the 90’s of the mono-charged ion source [1] based on a axisymmetric magnetic structure, the next step towards multicharged ion source has been undertaken with the Multigan ion source [2]. The preliminary results did not fully demonstrate the ability of this source to produce high charge states. Therefore, GANIL and Pantechnik got both involved in a collaboration to develop an ECRIS prototype using an optimized axisymmetric magnetic structure devoted to the production of high charge state ions at 10 GHz of RF frequency.
Magnetic structure has been designed, mechanic parts have been machined and assembled before setting this ion source called PKGANESA on a dedicated test bench at the Pantechnik company.
This contribution shall present the PKGANESA characteristics: magnetic structure, mechanical design, RF design as well as measurements done at Pantechnik on the charge states distributions obtained with Ar and the evolutions of CSD regarding RF power, bias electrodes and buffer gases.
