    摘要： The invention provides an ion source comprising first and second cathode pole pieces spaced apart from one another to form a cavity therebetween, an edge of the first cathode pole piece being spaced apart from an edge of the second cathode pole piece to define an elongate cathode gap between the respective edges of the pole pieces, the elongate cathode gap having a longitudinal axis; at least one magnet arranged for magnetising the first and second cathode pole pieces with opposite magnetic polarities; an elongate anode located in the cavity, the anode being spaced apart from the first and second cathode pole pieces and having a longitudinal axis, the longitudinal axis of the elongate anode and the longitudinal axis of the elongate cathode gap substantially coplanar; a first electrical connection which extends from outside the cavity to the anode; and a gas feed conduit which extends from outside the cavity to inside the cavity for introducing a gas into the cavity.

    摘要： A method for preparing zinc oxide nanostructures using arc discharge is disclosed. The method comprises the provision of an anode and a cathode in an arc discharge chamber. Current is supplied to the anode and the cathode to establish an arc discharge between the cathode and the anode to vaporise the anode and produce zinc oxide nanostructures. Contemplated is the use of the zinc oxide nanostructures to produce components that have applications in, for example, optoelectronics, energy storage devices, field emission devices, and sensors such as UV photosensors, gas sensors and humidity sensors. Disclosed is a gas sensor and method for its production, where said method comprises the provision of a sensor substrate comprising a conducting thin film at least partially covering at least two regions on at least one surface of a sensor substrate material to define a gap in the conducting thin film, the application of a mixture of zinc oxide nanostructures and a non-ionic polymer to at least a portion of the gap in the conducting thin film to thereby bridge the gap. Optionally contemplated is a step of annealing the mixture of zinc oxide nanostructures and non-ionic polymer applied to said sensor substrate to produce the sensor component.
