Title: A gas circulation and purification system for gas-cell-based low-energy RI-beam production

Abstract

A gas circulation and purification system was developed at the RIKEN Radioactive Isotope Beam Factory that can be used for gas-cell-based low-energy RI-beam production. A high-flow-rate gas cell filled with one atmosphere of buffer gas (argon or helium) is used for the deceleration and thermalization of high-energy RI-beams. The exhausted buffer gas is efficiently collected using a compact dry pump and returned to the gas cell with a recovery efficiency of >97%. The buffer gas is efficiently purified using two gas purifiers as well as collision cleaning, which eliminates impurities in the gas. An impurity level of one part per billion is achieved with this method.

  • A system is described for the circulation purification of neon during the operation of a large number of spark chambers. The system ensures purification of 800 liter/h of neon (under a pressure ranging from 0 to 2 mm of water and a maximum diffusion of 10 liter/h) and the composition of the gas mixture required for the operation of the chambers.
  • Energy straggling in a charge exchange cell, which is frequently used for negative ion production, was studied experimentally and compared with the results of theoretical evaluation. The change of the energy spectrum of a He{sup +} beam due to charge exchange processes in argon gas was measured in the energy range of 2-6 keV. Energy straggling by multiple collisions is expressed by the energy loss formula due to inelastic and elastic processes. The impact parameter is related to the elastic scattering angle, and the geometry of the charge exchange cell and other components of the beam transportation system determines themore » maximum acceptable scattering angle. The energy spread was evaluated taking the integral limit over the impact parameter into consideration. The theoretical results showed good agreement with those of actual measurement.« less
  • A beam energy recovery system for future neutral beam injectors based on negative ions has been designed. Residual negative ions are recovered electrically, while residual positive ions are decelerated on a soft-landing beam dump. This design simplifies the beam energy recovery power supply system an reduces the heat flux on the beam dump. Residual ions are separated into negative and positive ions by the stray magnetic field from the Fusion Engineering Reactor (FER). The next Japanese tokamak reactor. Each ion beam is also guided to the collector electrode and the soft-landing beam dump by the stray magnetic field. In themore » 500-keV/20-MW injector designed for FER, the total power efficiency can be improved from 46 to 59% by recovering the negative ions.« less
  • This paper reports on a beam direct energy convertor (BDC) designed to recover unneutralized ion beam energies in a 500-keV negative-ion-based deuterium neutral injection system for the Fusion Experimental Reactor of Japan Atomic Energy Research Institute. A newly developed three-dimensional beam transport code KUNABE-3 is used. Due to approximately equal fractions of unneutralized D{sup +} and D{sup {minus}} beams flowing from the gas neutralizer, electrostatic electron suppression is efficient. Also, magnetic separation and deflection of both species by a 1-kG magnetic field are efficiently applicable. Under suitable energy recovery conditions, perfect collection of both positive and negative ion beams ismore » theoretically achievable, even for a collector voltage of {plus minus}480 kV, resulting in 96% energy recovery efficiency. Within {plus minus}10% deviation from the reference parameters, the designed BDC shows excellent performance for such parameters as magnetic fields, incident beam energies, and gas line densities.« less
  • A beam emission spectroscopy (BES) system was developed for density gradient and fluctuation diagnostics in the Large Helical Device (LHD). In order to cover the large Doppler shift of the H{alpha} beam emission because of the high-energy negative-ion-based neutral beam atom (acceleration voltage V{sub acc}=90-170 kV) and the large motional Stark splitting due to the large vxB field (magnetic field B=3.0 T), a grating spectrometer was used instead of a conventional interference filter system. The reciprocal linear dispersion is about 2 nm/mm, which is sufficient to cover the motional Stark effect spectra using an optical fiber with a diameter ofmore » 1 mm.« less
