- Interaction between ion source plasma and ion source wall
WADA Motoi; KASUYA Toshiro; NISHIURA Masaki
Condition of the wall largely affects the performance of an ion source. Several fundamental mechanisms are responsible for the change in extractable amount of ions from the source. These include change of particle/energy reflection coefficient at the source wall due to formation of deposition layers, and alteration of dc electromagnetic structures near the source wall. Time-of-flight energy analysis for neutral particles, optical emission spectroscopy, and electrostatic probes were the three major tools employed to investigate factors governing the plasma-surface interactions in ion source plasmas. Peaks of velocity distribution functions of neutrals effusing out of plasma, shift toward the higher energy side with the increasing discharge power into the ion source. Vacuum ultraviolet spectra of hydrogen gas in a negative hydrogen ion source have shown the coverage of high temperature cathode materials alters distributions of molecular excitation levels of the gas confined in the ion source. High frequency electrical powers can excite plasma without any cathodes acting as sputtering/evaporation particle sources, but they still form deposition layers on ion source walls. The deposition layers formed by high frequency discharge power often show insulating characteristics causing change in local potential distributions around the ion extraction holes. The penetration of local electrical potential into plasma has been measured with the extraction potential turned on. The result has clearly shown the presence of field attracting ions to be extracted from the source. The extraction probability calculated from the local electric field has been compared with the experimental result. Plasma flow speed which is an input parameter for the theoretical model to predict extraction probability has been measured experimentally by dc laser photodetachment method. Other diagnostic methods to characterize plasma surface interaction like laser induced photoelectron emission have been developed to further deepen the understanding the plasma-surface interaction for ion source and process plasmas., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2005 -2007, Grant-in-Aid for Scientific Research (B), Doshisha University - Clarification of fundamental processes in negative ion plasma
WADA Motoi; KASUYA Toshiro; NISHIURA Masaki
Formation and destruction processes of negative ions were studied to clarify the factors affected by plasma-surface interaction at the wall of a plasma source confining a negative ion plasma. Simple dependence of negative ion density upon surface characteristic parameter like work function or tungsten coverage rate was not found obvious, but the negative ion density and/or the VUV spectrum of the light emission from the plasma appeared to be dependent upon plasma volume parameters as well. Electron energy distribution functions, perturbation upon extracted negative hydrogen ion (H^-) current due to laser injection into the ion source extraction region, and transport of perturbed plasma by photodetachement were investigated to clarify the effect of neutral collisions. A precise measurement of electron energy distribution function revealed the high energy component occupied larger portion than the one in a simple Maxwell distribution function. This corresponds to more frequent formation of vibrationally excited hydrogen molecules in the plasma. The collision processes were found influential upon the transport of H^- in hydrogen plasma through two mechanisms. The first is the deceleration of plasma due to neutral collision damping, and the second is an enhanced transport of H^- toward the extraction hole, which is presumed caused by a combination with the local electric field. Velocity distribution functions of neutral hydrogen atoms and molecules were measured by mass separated time-of-flight analysis. When the velocity distribution functions of D_2 molecules were fitted to Maxwell distribution functions, the molecular translational temperature increased with the discharge power up to a critical one, and then decreased against further increase of the power. The above experimental observations should form a set of key components to be taken into account for modeling the atomic and molecular processes in a negative ion containing plasma., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2002 -2004, Grant-in-Aid for Scientific Research (B), Doshisha University - physical pehnomena in strongly coupled plasma
