Abstract

Production and acceleration system of multiply charged C60 and C70 fullerene ions are being designed for basic studies on cluster physics. Multiply charged fullerene ions are produced by electron impacts. Ions selected by the analyzing magnet are accelerated up to 100 kV through an acceleration column. The ion source generates C60+(8.4 nA), C602+(4.5 nA), C603+(1.6 nA). C60+, C602+, and C603+ are accelerated up to 100, 200, and 300 keV, respectively. The alternating phase focus (APF)-interdigital H-mode (IH) linac was designed to accelerate C60+ ion (e=1/720) and C70+ ion (e=1/840) from 0.2 to 3.2 keV/amu with an APF and an operation frequency of 10 MHz.

Abstract

We have developed a laser coupling with an electron cyclotron resonance (ECR) ion source for trace element analysis of mineral samples at University of Tsukuba. A compact Q-switched Nd:YAG laser at 1064 nm wavelength with a pulse width of 8 ns and a maximum energy of 50 mJ is employed to ablate the sample materials as a means of introducing samples into the ECR plasma. Preliminary experiments were performed to focus the laser beam on a pure metallic target (Cu). The mean kinetic energy of the laser produced Cu ions is measured to 470 eV for the laser energy of 50 mJ by a simple time-of-flight method. Design for a laser coupling with an ECR ion source as a new application of mass spectrometry are reported. © 2004 American Institute of Physics. [ABSTRACT FROM AUTHOR]
