Title: Effect of the plasma instability on the beam intensity from RIKEN 18 GHz electron cyclotron resonance ion source

Abstract

We measured the beam oscillation of RIKEN 18 GHz electron cyclotron resonance ion source for various conditions. In this experiment, the frequency of the beam oscillation increases with increasing the gas pressure and decreases with increasing rf power. The oscillation frequency is strongly dependent on the negative voltage of biased disk, i.e., the frequency increases with increasing the negative voltage. We observed that the frequency is strongly dependent on the mass of ionized gas.

  • Beam intensities of highly charged Ar ions (Ar{sup 11+,12+}) were measured as a function of plasma electrode position. We observed that the beam intensity of Ar{sup 11+,12+} increased when putting the electrode far from the electron-cyclotron-resonance zone. On the other hand, lower charged heavy ions (Ar{sup 8+,7+}) dramatically decreased. We observed that the intense beam extraction strongly affects the plasma condition. It may be due to the ion pumping effect.
  • In order to produce a high-intensity and stable {sup 48}Ca beam from the RIKEN 18-GHz electron cyclotron resonance ion source, we have begun testing the production of a calcium beam using a micro-oven. To minimize the consumption rate of the material ({sup 48}Ca), we introduced the “hot liner” method and investigated the effect of the liner on the material consumption rate. The micro-oven was first used to produce the {sup 48}Ca beam for experiments in the RIKEN radioisotope beam factory, and a stable beam could be supplied for a long time with low consumption rate.
  • We measured the main plasma parameters (density of electron, temperature of electrons, and ion confinement time) as a function of B{sub min} and B{sub inj} with laser ablation technique. We observed that the B{sub min} mainly affects the temperature and density of electrons and all of the three parameters increase with increasing the B{sub inj}. We also observed that the gas pressure of the plasma chamber at the rf injection side became minimum at the optimum value for B{sub min} at fixed gas flow. This result indicates that the ionization efficiency becomes maximum at optimum value for B{sub min}. Frommore » these results, it is concluded that the plasma production is strongly dependent on the B{sub min} (plasma generator). We also observed that the B{sub inj} affects the ion confinement time, temperature, and density of electrons. All of the three parameters increase with increasing B{sub inj}.« less
  • For the RIKEN radio isotope factory (RIBF) project, we produced the multicharged uranium beam with two methods. To produce lower charge state U ion beams (14+-20+) we used the UF{sub 6} gas as an ionized gas. The typical beam intensity of U{sup 14+-20+} was 2-1 particle {mu}A at the extraction voltage of 14 kV. To produce higher charge state U ion beam (U{sup 35+}), we chose the sputtering method. The beam intensity was 70 particle nA at the extraction voltage of 5.4 kV. Using this method, we successfully produced multicharged U beam continuously for one month without break for RIBFmore » commissioning.« less
  • A RIKEN 18 GHz electron cyclotron resonance ion source (18 GHz ECRIS) is used as an external ion source at the Radioactive Ion Beam Factory (RIBF) accelerator complex to produce an intense beam of medium-mass heavy ions (e.g., Ca and Ar). In most components that comprise the RIBF, the control systems (CSs) are integrated by the Experimental Physics and Industrial Control System (EPICS). On the other hand, a non-EPICS-based system has hardwired controllers, and it is used in the 18 GHz ECRIS CS as an independent system. In terms of efficient and effective operation, the 18 GHz ECRIS CS asmore » well as the RIBF CS should be renewed using EPICS. Therefore, we constructed an 18 GHz ECRIS CS by using programmable logic controllers with embedded EPICS technology. In the renewed system, an operational log system was developed as a new feature, for supporting of the 18 GHz ECRIS operation.« less
