    6-GeV synchrotron radiation project : International conference on synchrotron radiation instrumentation (1989)

    Notes: This paper outlines the status of a 6-GeV synchrotron radiation designed at RIKEN. This facility consists of a main storage ring, a booster synchrotron, a 1.5-GeV preinjector linac, positron injection linacs, and others. The electronan GeV. The storage ring has a circumference of 1069.2 m and 7-m-long straight sections for insertion devices. The lattice of the main ring is a Chasman–Green-type one and has 36 periodicity. The low emittance (εx=8.2 nm rad) and large dynamic aperture are expected even with field errors and misalignments of magnetic elements. Three years of a preconstruction research and development period and 5 years of construction period are scheduled.

    Extraction of infrared radiation from SPring-8 : Proceedings of the 4th international conference on synchrotron radiation instrumentation (1992)

    Notes: Extraction of infrared beams from SPring-8 storage ring is investigated. SPring-8 is a third generation insertion device oriented synchrotron radiation source in x-ray region. It is noticeable, however, that a highly powerful radiation source in infrared region can be obtained from the bending magnet because of the large bending radius of 40 m. In this wavelength region, SPring-8 storage ring has a very sharp natural collimation in the vertical direction and the source size is very small. Extraction of infrared radiation in wavelength of 2–25 μm was designed. Source is a bending magnet and a water-cooled copper mirror is incorporated into the crotch laid just downstream by the bending magnet. The design of crotch and the transport system is carried out.

    Design of accelerator for negative ion beams by computer simulation (1985)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 58 (1985), S. 1701-1703

    Notes: We describe the computer simulation concerning the acceleration of the H− ion beams in the range of 150–450 eV. The method of H− ion production by bombarding the accelerated cluster ion beams with a small glancing incident angle on the cesiated metal surface is proposed. The computation of the spatial distribution and H− ion trajectory in the multiple stage ionizer is carried out by the iterative numerical method of Laplace equation. The numerical simulation indicates nearly 100% of the H− ion beams from the cesiated metal surface will be accelerated and appear in the output.

    Application of the electrostatic energy analyzer to cluster size measurement (1986)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 60 (1986), S. 1532-1534

    Topics: Physics
    Notes: An electrostatic energy analyzer with a deflection angle of 90° and a resolving power of about 4% up to 200 keV was used to analyze the distribution from a cluster ion source. The experiments were carried out with cluster-ion beams of nitrogen extracted from a specially designed cluster ionizer for controlling the cluster sizes. It is shown that the cluster size as large as ∼105 atoms/cluster is measurable with this energy analyzer.

    Multiply charged carbon ions produced from C2H2 and CH4 molecules in energetic, heavy ion impact (1986)

    Notes: Abstract Multiply charged carbon ions up to C5+ ions have been observed from C2H2 and CH4 molecules in 1.05 MeV/amu Ar12+ ion impact. These ions are believed to be produced through processes where multiply charged molecular ions are produced first by direct ionization and, then, dissociate via Coulomb explosion into atomic ions. The peak positions of ions from C2H2 molecules are found to be shifted with respect to those of ions from CH4 molecules and this shift is understood to be due to the initial kinetic energy provided through the Coulomb potential between the dissociating ions.
