Development of a high brightness hydrogen ion source for the basic technology accelerator (BTA)

Abstract

A high brightness hydrogen ion source has been developed for the 10 MeV/10 mA proton beam accelerator, BTA, at JAERI. The bucket type ion source generates the source plasma by arc discharge using tungsten filaments, and the plasma is confined in the plasma chamber by strong cusp magnetic field for enough time to enhance the proton yield. Two stage extraction system is adopted to obtain convergent ion beams. Recently, the prototype ion source for BTA was constructed and the first experiment was performed at the negative ion source test facility (ITS-2M) to investigate the beam properties of the source. The results of the experiments are as follows; a hydrogen ion beam of 56 mA was extracted with a low normalized emittance of 0.5 {pi}mm{center_dot}mrad (90 %) and high proton yield of 80 %, at an acceleration voltage of 60 kV.
