“…A high-intensity C60 ion beam of a hundred pico-ampere level at an energy of 6 MeV can be available using a helium stripper gas and is mainly supplied to develop a highly sensitive surface analysis by means of time of flight mass spectrometry. All ions that form a stable negative ion, including cluster ions such as Cn (n = 2 to 10) and Aun (n = 2 to 4) [19] can be produced by the SNICS II, while negative C60 ions are produced with an electron attachment method originally developed at TIARA [20]. The charge exchange type RF ion source is used exclusively for production of unstable negative helium ions.…”

Abstract:The ion beam facility at the Takasaki Advanced Radiation Research Institute, the National Institutes for Quantum and Radiological Science and Technology, consists of a cyclotron and three electrostatic accelerators, and they are dedicated to studies of materials science and bio-technology. The paper reviews this unique accelerator complex in detail from the viewpoint of its configuration, accelerator specification, typical accelerator, or irradiation technologies and ion beam applications. The institute has also irradiation facilities for electron beams and 60 Co gamma-rays and has been leading research and development of radiation chemistry for industrial applications in Japan with the facilities since its establishment. The configuration and utilization of those facilities are outlined as well.

“…Cluster ion beams in the energy region mentioned above can be provided using a conventional tandem accelerator. The Takasaki Ion Accelerators for Advanced Radiation Application ͑TIARA͒ facility can produce and accelerate B n , C n , Si n , Al n , Ge n , Cu n , Ag n , Au n ͑n Ϲ 10: for carbon͒, 3 and C 60 cluster ions with a 3 MV tandem accelerator at energies of up to 12 MeV ͑C 60 3+ ͒. Some of the applications developed at the TIARA facility have already been reported in Refs.…”

The transmissions of carbon cluster ion beams through a tandem accelerator using several stripper gases (He, N2, CO2, and SF6) with a terminal voltage of 2.5 MV were measured as a function of the gas pressure in investigating the most suitable gas for cluster ion acceleration. This resulted in it being demonstrated that the highest transmission could be obtained using the smaller size gas, i.e., helium displayed the best performance of the four gases used. In addition, the ratio of transmissions of C(n) with helium and nitrogen increased with increases in the n, thus revealing that helium gas should prove the most effective in larger cluster ion acceleration using the same energy.

“…The ions were injected into the target PC films attached to an aluminum sample holder by double-sided conducting tape. The irradiations were performed at a primary particle fluence rate below 10 11 below 5ϫ10 Ϫ8 Torr, and the incident angle of the beam was normal to the sample surface. A current at the target I t and an emission current by secondary charged particles I s were simultaneously measured by two high-sensitivity electrometers ͑ADVANTEST model 8240͒.…”
