Hydrogen atomic pair-ion production on catalyst surface

Abstract

To generate a hydrogen pair-ion plasma consisting of only hydrogen atomic pair ions, i.e., H(+) and H(-) ions, the efficient production of pair ions is required. When discharged hydrogen plasma is irradiated to a Ni catalyst, pair ions are produced on the catalyst surface. It is clarified that hydrogen chemisorption on the catalyst affects pair-ion production.

Separation of ion components produced by plasma-assisted catalytic ionization

“…To overcome this difficulty, we have proposed a plasma-assisted catalytic ionization method for the production of positive and negative hydrogen ions. [23][24][25][26] When positive hydrogen ions produced by discharge are irradiated to a porous catalyst, the hydrogen ions are produced from the back of the irradiation plane. In this paper, the properties of the produced ions are discussed in detail.…”

Development of Hydrogen Pair-Ion Source on the Basis of Catalytic Ionization

“…In our previous work, a Penning ionization gauge (PIG) discharge plasma was used for positive-ion irradiation to a porous catalyst [11]. The both irradiation energy and flux of positive ions depend on the discharge power (anode voltage).…”

“…It is difficult to satisfy these requirements in surface production with a cesium admixture or in volume production. In order to solve this difficulty, we have suggested a catalytic ionization method with plasma assistance [11].…”

Landau damping of ion acoustic wave in Lorentzian multi-ion plasmas

“…1,2 The multi-ion plasmas are studied theoretically as well as experimentally in different ways such as bi-ion plasmas, [3][4][5] pure pair-ion plasmas, [6][7][8][9][10] and pair-ion with electron plasmas. 11,12 In order to study ion acoustic wave in negative ion plasma both Ar=SF 6 and K=SF 6 plasmas have been generated in Q-machines by dc discharges.…”
