Abstract
A universal pocket PIG ion source with a permanent magnet has been dev eloped by our institute. Usually the source can produce single and mul tiple charged ions of gas or metal elements. At 20-30 kV extraction vo ltage, milliamperes of gas ions, and tens of mu A A Of metal ions can be extracted with less than 50 W of discharge power consumption. And n egative ions of some elements with larger electron affinity can be ext racted directly from the source. Thus far, using LaB6 as a cathode, mo re than 50 mu A Of H-, about 1.4 mA of O-, and 1.8 mA of F- ions in to tal beam have been extracted at 15-20 kV extraction voltage. The power consumptions are less than 40, 50, and 100 W, respectively. (C) 1996 American Institute of Physics.
