Commissioning and first operation of a 500 mu A, 30 MeV, H- cyclotron: the TR30

A high-intensity 30-MeV H/sup -/ cyclotron has been constructed for NORDION International to be used for radioisotope production at the TRIUMF site. It is a four-sector radial ridge design with two 45 degrees dees in opposite valleys. An external multi-cusp DC ion source generates the beam for axial injection into the cyclotron. Two multiple-foil stripping mechanisms produce two simultaneous beams, each of intensities up to 250 mu A. First beam was achieved on May 9, 1990. The initial acceptance tests were completed on July 20, 1990, finishing the project within the 19-month construction schedule. Since then the machine has been used for regular isotope production and operator training.<
