One should pay attention to quite a lot of factors when the emittance of high-current ion beam is measured. The background subtraction and threshold setting,the measuring method of pulsed beam emittance,as well as the...
To meet the requirements of developing SFRFQ and upgrading the 1 MeV ISR RFQ accelerator,an ECR O^+ ion source and LEBT system have been developed.Using two Einzel Lenses to focus the beam,more than 3mA O^+ beam with ...
This paper presents new beam test results for O^+ beam on a high current Integral Split Ring Radio Frequency Quadruple(ISR RFQ)accelerator.After the upgrading,a new designed 2.45GHz O^+ ECR Ion Source can provide a be...
