Cesiation in Highly Efficient Surface Plasma Sources

Cesiation effect, a significant enhancement of negative ion emission from a gas discharge with decrease of coextracted electron current below negative ion current was observed for the first time on July 1, 1971 by location into discharge a compound with one milligram of cesium [1]. This observation became the basis for the development of Surface Plasma Sources (SPS) for highly efficient product...

Conceptual Design of a Sputter-type Negative Ion Source Based on Electron Cyclotron Resonance Plasma Heating

A design for a negative ion source based on electron cyclotron resonance plasma heating and ionization by surface sputtering is presented. The plasma chamber of the source is an rf-cavity designed for TE111 eigenmode at 2.45 GHz. The desired mode is excited with a loop antenna. The ionization process takes place on a cesiated surface of a biased converter electrode (cathode). The ion beam is fu...

Hydrogen pair-ion production by catalytic ionization

Pair plasmas consisting of only positiveand negative-charge particles of equal mass have attracted special attention because they maintain space-time symmetry. A fullerene pair-ion plasma, consisting of positive and negative ions of equal mass (C60 and C60), has been generated and its collective phenomena have been investigated experimentally [1]. In order to investigate more extensive physical...

Sheath structure in negative ion sources for fusion (invited).

In fusion negative ion sources, the negative ions are formed on the caesiated plasma grid predominantly by hydrogen atoms from the plasma. The space charge of the negative ions leaving the wall is not fully compensated by incoming positive ions and at high enough emission a virtual cathode is formed. This virtual cathode limits the flux of negative ions transported across the sheath to the plas...
