Abstract: A cluster tool includes multiple tools for microscopic processing of a sample positioned around a rotatable base. A sample holder on the base rotates the sample between the working areas of the tools. A slidable vacuum seal maintains a vacuum in a sample chamber for tools that require a vacuum.

Abstract: An improved system for delivering propane or other consumable liquid to remotely located storage tanks including a novel combination of remote monitoring of customer tanks and an improved method of using the remote monitoring data to optimally schedule deliveries, improve safety, and more efficiently operate a propane dealership. More accurate and timely information concerning the status of customer tanks serves to improve operational efficiencies and increase safety. Data received from remote sensors can be collected and organized so that it is easily understood and utilized through the implementation of a user interface accessible via the Internet that allows the information to be presented in an efficient graphical and contextual fashion. Operational efficiencies can also be improved by taking historical propane usage for each tank, weather conditions, and projected fuel usage into account.

Abstract: The invention provides an electron source suitable for use in a charged-particle apparatus, in which source a beam of electrons can be extracted from an electrode that is subjected to at least one of an electric potential, thermal excitation and photonic excitation, whereby at least part of the electrode comprises semiconductor material having a conduction band that is quantized into discrete energy levels. Such a source enjoys a relatively low energy spread, typically much smaller than that of a Cold Field Emission Gun (CFEG). The semiconductor material may, for example, comprise a semiconductor nanowire including InAs and GaInAs.

Abstract: The invention describes a particle-optical apparatus arranged to focus a beam (1) of electrically charged particles with the aid of two particle-optical lens systems (10, 20). The lens action is achieved by magnetic fields, which fields are generated by permanent-magnetic materials (13, 23). In contrast to magnetic lenses equipped with a coil, it is not easy in the case of lenses equipped with permanent-magnetic material to alter the focusing magnetic field with the aim of altering the optical power. In an apparatus according to the invention, the optical power of the lens systems is altered by altering the energy with which the beam (1) traverses the lens systems (10, 20). This can easily happen by altering the voltage of electrical power supplies (14, 24).

Abstract: A method and system for organizing windows associated with an application are described. In one embodiment, a user command pertaining to multiple internal windows is received. The multiple internal windows are contained within a first frame controlled by an application. In response to the user command, a second frame controlled by the application is opened. Further, one or more of the multiple internal windows are moved to the second frame. In one embodiment, the internal windows are moved to the second frame in response to an operation performed by a user (e.g., a drag-and-drop operation). Alternatively, the internal windows are moved to the second frame automatically based on a criterion controlling the organization of the internal frames.

Abstract: A nanostructure is fabricated using charged particle deposition to deposit a catalyst on a substrate. A charged particle beam is directed to location on the substrate where the catalyst is to be deposited, with a beam-activated precursor gas also being directed to the location. For example, a nickel dot can be selectively deposited onto a substrate by using a charged particle beam to decompose a nickel-containing precursor gas, and then a carbon nanotube can be grown on the nickel dot, with the diameter of the nanotube conforming to the size of the nickel dot.

Abstract: The present invention provides an inductively coupled, magnetically enhanced ion beam source, suitable to be used in conjunction with probe-forming optics to produce an ion beam without kinetic energy oscillations induced by the source.
