Ion track technology has been developed to fill certain niche areas where conventional nanolithography fails, including: Direct shaping of radiation-resistant minerals, glasses and polymers [2] Generation of elongated structures with a resolution limit down to 8 nanometers [7] Meer weergeven Ion tracks are damage-trails created by swift heavy ions penetrating through solids, which may be sufficiently-contiguous for chemical etching in a variety of crystalline, glassy, and/or polymeric solids. They are associated … Meer weergeven Ion track technology deals with the production and application of ion tracks in microtechnology and nanotechnology. Ion tracks can be selectively etched in many insulating … Meer weergeven When a swift heavy ion penetrates through a solid, it leaves behind a trace of irregular and modified material confined to a cylinder of … Meer weergeven Etched ion tracks can be replicated by polymers or metals. Replica and template can be used as composite. A replica can be separated from its template mechanically or chemically. Polymer replicas are obtained by filling the etched track with a liquid precursor of … Meer weergeven The class of ion track recording materials is characterized by the following properties: • High homogeneity: Local density variations of … Meer weergeven Selective ion etching Selective ion track etching is closely related to the selective etching of grain boundaries and crystal dislocations. The etch process must be sufficiently slow to discriminate between the irradiated and the pristine … Meer weergeven Microtechnology: The common mechanical tools of the macroworld are being supplemented and complemented, and in some applications replaced by, particle beams. … Meer weergeven WebLinear energy transfer is best defined for monoenergetic ions, i.e. protons, alpha particles, and the heavier nuclei called HZE ions found in cosmic rays or produced by particle …

Web13 jul. 2012 · The ions are detected by a solid-state particle detector placed behind the sample. As soon as the detector has registered a single ion impact, the entire ion beam is deflected by an electrostatic chopper system. A schematic representation of the single-ion irradiation system is presented in Figure 1b. WebLinear energy transfer is best defined for monoenergetic ions, i.e. protons, alpha particles, and the heavier nuclei called HZE ions found in cosmic rays or produced by particle accelerators. These particles cause frequent direct ionizations within a narrow diameter around a relatively straight track, thus approximating continuous deceleration.
