Abstract: In a method for producing a directed gas jet wherein a guided sample gas beam is generated and an auxiliary gas beam is generated and directed and guided in the same direction as, but separated from, the sample gas beam, a pulsed carrier gas stream is generated and combined with the sample gas beam such that the sample gas beam is separated into spaced pulses which are embedded between the axially spaced pulses of the carrier gas beam and the carrier gas beam with the sample gas beam embedded therein is combined with the auxiliary gas beam such that the carrier and sample gas beam is radially enveloped by the auxiliary gas beam to from the directed gas jet of a carrier and sample gas pulses enveloped in the auxiliary gas beam.

Abstract: A field emission device having emitter tips and a support layer for a gate electrode is provided. Openings in the support layer and the gate layer are sized to provide mechanical support for the gate electrode. Cavities may be formed and mechanically supported by walls between cavities or columns within a cavity. Dielectric layers having openings of different sizes between the emission tips and the gate electrode can decrease leakage current between emitter tips and the gate layer. The emitter tips may comprise a carbon-based material. The device can be formed using processing operations similar to those used in conventional semiconductor device manufacturing.

Abstract: An electron collector assembly for an electron beam tube comprises an electr on collector (2), which is at least partially surrounded by dielectric material , such as a dielectric fluid (5). A heat pipe (6), in communication with the dielectric fluid, is provided. Heat energy from the collector is transferred to the dielectric fluid, and hence to the heat pipe. By pumping coolant through the heat pipe, heat energy is removed from the vicinity of the collector. Previous proposals for cooling electron collectors necessarily involved non-conducting fluids as coolants. The provision of a dielectric fluid as an intermediary between the collector and the heat pipe allows greater freedom in the choice of coolant.

Abstract: The invention relates to a monochromator on the basis of Wien filters. According to a first aspect, four Wien filters are arranged in series along a common optical axis of which the two center Wien filters are each rotated by 90° relative to the two outer Wien filters. The two center Wien filters (W2, W3) are orientated simultaneously anti-parallel to each other. Such a monochromator has inherent stigmatic imaging characteristics and is, as a unit, free of dispersion. According to a further aspect, each of the Wien filters is configured symmetrically with reference to a 90° rotation about the optical axis. The magnetic and the electrostatic poles of the Wien filter are identically dimensioned so that the orientation of the Wien filter azimuthally about the optical axis (OA) can be varied by a corresponding drive of the particular contacts for the voltage supply and current supply of the electrodes and coils.

Abstract: A cold cathode closed drift ion source is provided with segregated gas flow. A first gas may be caused to flow through or along a path around a peripheral portion of an anode so as to pass through the electric gap between the anode and cathode. A second gas (different from the first gas) may be caused to flow toward the ion emitting slit, without much of the second gas having to pass through the electric gap(s). If it is desired to utilize a gas which produces insulative material (e.g., an organosilicon gas), this gas may be used as the second gas. Accordingly, insulative material buildup in the electric gap between the anode and cathode may be reduced, and changes in beam chemistry can be achieved without unduly altering ion beam characteristics.

Abstract: An ion source (12) embodying the present invention is for use in an ion implanter (10). The ion source comprises a gas confinement chamber (76) havi ng conductive chamber walls that bound a gas ionization zone. The gas confineme nt chamber includes an exit opening (78) to allow ions to exit the chamber. A b ase (120) positions the gas confinement chamber relative to structure for formin g an ion beam from ions exiting the gas confinement chamber. A gas supply is in communication with the gas confinement chamber for conducing an ionizable ga s into the gas confinement chamber. A cathode (124) is supported by the base and positioned with respect to said gas confinement chamber to emit ionizaing el ectrons into the gas ionization zone. The cathode comprises a tubular conductive bod y (160, 162) that partially extends into the gas confinement chamber and includes a conductive cap (164) that faces into the gas confinement chamber for emittin g ionizaing electrons into the gas confinement chamber. A filament (178) is su pported by the base (120) at a position inside the tubular conductive body of the ca thode for heating the cap and cause the ionizing electrons to be emitted from the cap into the gas confinement chamber.

Abstract: Prior art quiet docking and undocking methods used an interface that was located within the notebook computer, thus adding to the cost, complexity, weight, and power consumption of the notebook computer. The present invention provides for an apparatus for quiet docking of a notebook computer to a docking station, including interface circuitry located within the docking station. The interface detects when the notebook computer has been inserted within the docking station, and correspondingly enables a switch such that a common system bus is coupled between the notebook computer and the docking station. The interface also generates events to allow a software routine to configure the notebook computer and docking station without prior user intervention. The interface also includes circuitry to detect an undock request, and correspondingly undock the computer such that a transaction occurring on the system bus is not affected.

Abstract: A data conversion system and method which converts data between different software and hardware platforms. The DCLE of the present invention converts data from any number of different types or formats from any of various platforms to a single common data standard having a pre-defined generic data type, and the data is then converted from this generic type to a new desired format or type and stored on an existing or new destination platform. Thus, the system and method of the present invention allows for multiple database conversions to be created easily and efficiently. The data conversion process begins by first defining a complete data map of the input and output data environments, as well as zero or more intermediate environments. Data objects referred to as data bridges and streams are created to logically connect or associate the input and output environments as well as the tables in the input and output data environments. In response to user input, the data conversion system and method creates an association between fields or parts in the tables (units) in the input environment and the fields in the output environment. This essentially involves creating user specified mappings between fields in the input data environment and fields in the output data environment. When an execute command is received, the data conversion system and method accesses data from the first input environment, i.e., accesses data from the storage medium storing the data to be converted, and converts the data from the first input data environment to data having a pre-defined generic data type. Converting the data first to a pre-defined generic data type greatly simplifies the conversion process, since conversion code is only required to and from the generic data type and is not required between every possible data format. Thus, the development of conversion code is much simpler and more efficient. Once data has been converted to the generic data object, the associations are executed to convert the data from the pre-defined genetic data type to the output data using the second data format.
