Surface production of negative hydrogen ions
- 1. Department of Physics and Engineering Physics, Stevens Institute of Technology, Hoboken, NJ 07030 (United States)
Description
Experimental data on generation of negative hydrogen ions on cesiated molybdenum surfaces are presented. The following processes are discussed: backscattering of protons and H2+ ions, sputtering of adsorbed hydrogen by cesium ion bombardment, and backscattering of a thermal or superthermal distribution of hydrogen atoms. The data are compared with theoretical calculations. Surface production is an important process in most negative hydrogen ion sources. An example of a negative hydrogen ion gun using hyperthermal hydrogen atoms incident on an external converter is presented
