Article: KEKCB electron cyclotron resonance charge breeder at TRIAC.
[show abstract] [hide abstract]
ABSTRACT: The KEKCB is an electron cyclotron resonance (ECR) ion source for converting singly charged ions to multicharged ones at Tokai Radioactive Ion Accelerator Complex. By using the KEKCB, singly charged gaseous and nongaseous ions were converted to multicharged ones of A/q approximately 7 with efficiencies of 7% and 2%, respectively. The conversion efficiency was found to be independent of the lifetime of the radioactive nuclei having lifetimes of the order of one second. Three collimators located at the entrance and the exit of the KEKCB defined the beam axis and facilitated beam injection. Grinding and washing the surfaces of aluminum electrode and plasma chamber dramatically reduced impurities originating from the ECR plasma of the KEKCB.Review of Scientific Instruments 03/2008; 79(2 Pt 2):02A906. · 1.37 Impact Factor -
Article: KEKCB-18GHz ECR charge breeder at TRIAC
[show abstract] [hide abstract]
ABSTRACT: The KEKCB is an electron cyclotron resonance ion source (ECRIS) operating at the microwave frequency of 18 GHz and has successfully operated as the charge breeder at Tokai Radioactive Ion Accelerator Complex (TRIAC). Following an overview of the TRIAC, the recent operating results of the KEKCB have been demonstrated. Special attention was paid on the element-dependent charge breeding efficiency and the beam impurity originating from the ECR plasma of the KEKCB.Nuclear Instruments and Methods in Physics Research Section B Beam Interactions with Materials and Atoms 266:4411-4414. · 1.21 Impact Factor
