摘要：

In the last two years the development of the large-capacity oven was continued. First tests on-line with calcium, lead, tin and magnesium beams were achieved. We successfully produced 30 mu A of Ca9+, 13 mu A of Pb23+, 8 mu A of Sr21+, and 50 mu A of Mg7+. Some deformation of the filament appeared when working at high temperature. Several configurations of the filament and the use of an alternate power supply have been tested to solve this problem. The beam's intensities and the ionization efficiencies were improved in comparison with the standard microoven performances. The results of magnesium beam, 110 mu A of Mg5+ obtained with the "MIVOC" method are compared with those using the oven technique. (c) 2006 American Institute of Physics.
