摘要： A particle detection device includes a ceramic housing, a charge generator that adds electric charge generated in accordance with electric discharge to particles in gas introduced into a gas channel so as to turn the particles into charged particles, a collector that collects the charged particles, and a number measuring device that detects the number of particles based on an electric current that changes in accordance with the charged particles collected by the collector. The collector has a collection electrode exposed in the gas channel and a counter electrode facing the collection electrode with the gas channel interposed therebetween. The housing has a guard electrode that absorbs a leakage current flowing from the counter electrode toward the collection electrode via the housing.

摘要： The present invention is direct to a nano-probe corona tool and uses thereof. A nano-probe corona tool is disclosed having a tip with a diameter in the nano-scale, typically around 100 nm. The nano-probe corona tool is constructed of electrically conductive material. On the other end of the tool, a pulsed voltage source outputs a pulsed voltage to generate a pulsed electrical potential at the tip. The pulsed electrical potential at the tip causes a plasma discharge corona to occur. Uses of the corona discharge include, but are not limited to, optical emission spectroscopy, in the enhancement of deposition of coatings and nanoscale welding, e.g., nanotube or nanowires to a contact pad and welding two nanowires together, and in nanoscale surgery. For example, a nano-probe comprising CNTs may be inserted into cell membranes. The resulting corona discharge may be used to destroy tumors within the cell.

摘要： An aging treatment is performed by using cleaning gas obtained by mixing inert gas, as an impurity, to plasma gas. Plasma generation by dielectric-barrier discharge is performed until a predetermined period of time has elapsed by applying high AC voltage to an electrode while supplying the cleaning gas to a dielectric tube from a gas inlet.

摘要： An ion mobility spectrometer has a pair of electrodes and midway along the drill chamber. A high field is applied between the electrodes and sufficient to modify ions in the region of the electrodes such that they move at a different rate towards the collector plate. This is used to modify the time of flight of selected ions or ion clusters and enable identification of ambiguous peaks on the IMS spectrum.
