SOME PRACTICAL MODIFICATIONS ON HIGH FREQUENCY ION SOURCES (in Hungarian)
A radiofrequency ion source was constructed for the 800-kv cascade type accelerator and 300-kv neutron generator built in the Institute. Besides the usual transversal magnetic field of 50 gauss, an axial magnetic field of 250 gauss intensity was also applied in the immediate neighborhood of the probe. As a result of this, the service life of the discharge tube was increased by several hundred hours but in comparison with the measurements of other authors the percentage of protons underwent no change. The quartz calyx which was built to surround the probe, contributed considerably to an increase of the service life. Measurements concerning the selection of the pre-focusing lens are summarized. With a probe of 1.3-mm canal diameter, a maximum 1.9 ma pre-focused ion current was obtained in H/sub 2/ with a gas consumption of 8 to 10 cm/sup 3//hr, (With a probe of 1.7-mm canal diameter, at a gas consumption of 25 cm/sup 3//hr, 2.7 ma current was obtained.) The total consumption of the ion source amounted to 800 w with prefocusing. The energy-spread of the ion beam was found to be 200 ev. Having built it into the cascade type accelerator 1 ma current was measured on the target at an accelerating voltage of 500 kv, where this amount included the secondary electrons as well. (auth)
