Notes:
The metal ions from the volatile compounds (MIVOC) method was developed at the Accelerator Laboratory, University of Jyväskylä, in order to produce metal ion beams with the source material at or near room temperature conditions. It has been used with the JYFL-ECR ion source since 1993 and has turned out to be both simple and reliable. The method was adopted at several laboratories. Up to the present time, at least 17 MIVOC beams were produced (C, Mg, Si, Cl, Ti, V, Cr, Fe, Co, Ni, Ge, Mo, Ru, Sn, I, W, and Os). With the MIVOC technique it was found possible to operate the JYFL-ECR ion source with compounds of metals, either powders or liquids, that have a room temperature vapor pressure of the order of 1E–3 mbar or higher. The MIVOC method has turned out to be very economical in use since a typical material consumption rate is about 0.3 mg/h. This corresponds to the consumption rate of gases. Due to the simplicity of the system the duty-off time of the ion source is minimized. In this article, the basis of the MIVOC method, phenomena related to it and some results will be presented. © 1998 American Institute of Physics.
