An ion beam device according to the present invention includes a gas field ion source () including an emitter tip () supported by an emitter base mount (), a ionization chamber () including an extraction electrode () and being configured to surround the emitter tip (), and a gas supply tube (). A center axis line of the extraction electrode () overlaps or is parallel to a center axis line (A) of the ion irradiation light system, and a center axis line () passing the emitter tip () and the emitter base mount () is inclinable with respect to a center axis line of the ionization chamber (). Accordingly, an ion beam device including a gas field ion source capable of adjusting the direction of the emitter tip is provided.

Provided is an ion beam device provided with a gas electric field ionization ion source which can prevent an emitter tip from vibrating in a non-contact manner. The gas electric field ionization ion source is comprised of an emitter tip () for generating ions; an emitter base mount () for supporting the emitter tip; an ionizing chamber which has an extraction electrode () opposed to the emitter tip and which is configured so as to surround the emitter tip (); and a gas supply tube () for supplying gas to the vicinity of the emitter tip. The emitter base mount and a vacuum container magnetically interact with each other.

Provided are a large-current and highly stable gas field ionization ion source, and a high-resolution ion microscope with a large focal depth. The present invention relates to an ion microscope provided with a gas field ionization ion source, in which disposed are a refrigerator for cooling the gas field ionization ion source independent of the main body of the ion microscope, and a refrigerant circulation circuit cooling mechanism for circulating a refrigerant between the gas field ionization ion source and the refrigerator. Consequently it is possible to reduce the mechanical vibration of the refrigerator, which propagates to the gas field ionization ion source, and to achieve both the improvement of the brightness of the ion source and the improvement of ion beam focusing performance.

A waste water purification system for purifying polluted salt water including oil and the like by coagulating and separating pollutant matter in the polluted salt water can regenerate and reuse a coagulant in the system while scarcely resupplying the coagulant, an acid solution and an alkaline solution. The acid and alkaline solutions are required for disintegrating coagulated flocs from the polluted salt water and regenerating the coagulant from sludge. Alkaline water enriched in sodium hydroxide and an acidic aqueous solution containing hydrochloric acid and the like are generated by electrolyzing the purified salt water. The flocs in the separated sludge are disintegrated by use of the alkaline water, pollutant matter is removed from the disintegrated aqueous solution, and the strong acidic containing the hydrochloric acid is added to the aqueous solution removed of the pollutant matter to have the coagulant. The coagulant can be thus regenerated from the recovered sludge.
