Abstract: A vaporizer generating feed gas for the arc chamber of an ion source has a crucible which is heated to a temperature at which material in the crucible sublimes to produce a vapour for use as the feed gas. In addition to the heating element for heating the crucible, there is a cooling element in the form of a cooling duct extending along the length of the crucible for receiving the cooling fluid. Forced cooling of the crucible when the heating element is switched off enables the crucible to be cooled more quickly so that the supply of a feed gas can be terminated sooner. This is important if an ion source is being switched from one feed gas to another. Also, the crucible may be forced cooled simultaneously while energizing the heating element to enable the crucible to be accurately controlled at a lower operating temperature if desired.

Abstract: A computer program and method for controlling the manner in which an operating system associated with a computer launches a plurality of application programs. Briefly described, one of many possible embodiments is a computer program for use in a computer having an operating system. The computer program may comprise code for: determining application programs that are to be launched by the operating system; determining a program launch procedure associated with the application programs, the program launch procedure defining a sequence in which the application programs are to be launched by the operating system, the sequence based on the functionality of at least one of the application programs; and launching the application programs with the operating system based on the program launch procedure.

Abstract: Systems and methods are described herein for managing remote transmission destinations for a fax/scan device connected—directly or indirectly—to a network. When a fax/scan device is set to a “Receive Fax to PC” or “Scan-To PC” mode, a master host identifier that uniquely identifies a master host on the network is stored at the master host and at the fax/scan device. If another network computer attempts to supercede an existing master host for the fax/scan device, it is prevented from doing so because of the presence of the master host identifier in the fax/scan device. When the “Receive Fax to PC” or “Scan-To PC” mode is cleared, the master host identifier is also cleared. Only then may a network computer configure itself as a master host for the fax/scan device.

Abstract: An ion implanter has an ion source (10) and an ion beam extraction assembly (50) for extracting the ions. The extraction assembly (50) is a tetrode structure and one of the pairs of extraction electrodes (51) has left and right ports (54, 55) located in opposite sides of the ion beam emerging from the ion source (10). The left and right electrode ports (54, 55) are electrically isolated from each other and connected to independent voltage sources (210, 230). The ion implanter also has a baffle plate (60) at the entrance to a mass analyser (90) downstream of the extraction assembly (50). The baffle plate (60) is also split into two halves (60? and 60?). By measuring the beam current incident on the two halves (60?, 60?) of the baffle (60), the relative voltages supplied to the left and right electrode parts (54, 55) may be adjusted so as to steer the ion beam and adjust the angle of incidence of the longitudinal axis thereof relative to the input of the analysing magnet (90).

Abstract: An implementation of a technology, described herein, for facilitating the ease of handling and exchange of digital images. With at least one implementation of the invention, described herein, a set of selected digital images are collected together into a self-contained package called a photo album. This album includes the selected images and executable software to view such images. This album may be transmitted (typically, via email) to another via a network, such as the Internet. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.

Abstract: An ion beam apparatus comprises a source of ions (1), an evacuatable chamber (11), first and second electrodes (3, 5) disposed within the chamber for forming an ion beam from ions from the ion source, the first electrode being electrically insulated from the second electrode. At least one insulating member (31, 33), at least part of which is within the chamber provides the insulation, wherein a part of the insulating member is positioned adjacent the wall of the chamber. Alternatively, means for feeding coolant proximate the insulating member is provided to withdraw heat from the insulating member.
