摘要： A method for building hollow insulator cylinders that can have each end closed off with a high voltage electrode to contain a vacuum. A series of fused-silica round flat plates are fabricated with a large central hole and equal inside and outside diameters. The thickness of each is related to the electron orbit diameter of electrons that escape the material surface, loop, and return back. Electrons in such electron orbits can support avalanche mechanisms that result in surface flashover. For example, the thickness of each of the fused-silica round flat plates is about 0.5 millimeter. In general, the thinner the better. Metal, such as gold, is deposited onto each top and bottom surface of the fused-silica round flat plates using chemical vapor deposition (CVD). Eutectic metals can also be used with one alloy constituent on the top and the other on the bottom. The CVD, or a separate diffusion step, can be used to defuse the deposited metal deep into each fused-silica round flat plate. The conductive layer may also be applied by ion implantation or gas diffusion into the surface. The resulting structure may then be fused together into an insulator stack. The coated plates are aligned and then stacked, head-to-toe. Such stack is heated and pressed together enough to cause the metal interfaces to fuse, e.g., by welding, brazing or eutectic bonding. Such fusing is preferably complete enough to maintain a vacuum within the inner core of the assembled structure. A hollow cylinder structure results that can be used as a core liner in a dielectric wall accelerator and as a vacuum envelope for a vacuum tube device where the voltage gradients exceed 150 kV/cm.

摘要： A CT Fluoro system which, in one embodiment, includes an integrated controller, image reconstruction algorithms for increasing the speed of image display, and an enhanced image display, is described. The integrated controller enables the radiologist to maintain control of the system throughout the fluoro scan. The image reconstruction algorithms are generally directed to increasing the image frame rate or reducing image artifacts, or both, in the CT fluoro scan. The image display generally provides enhanced images and control to the radiologist during a scan procedure.

摘要： A system and method including an apparatus for use in electrically loading RF coils of an MRI system is disclosed. The apparatus includes a polymer interdispersed with an electrically conductive additive such that the apparatus provides the necessary electrical loading of the RF coils for testing and calibration of the MRI system but is free of liquid. Furthermore, the apparatus is capable of providing the requisite electrical load in high magnet magnetic fields without introducing image distortion as a result of standing waves within the apparatus.

摘要： An RF coil loop assembly technique that maintains coil isolation at varying coil positions is presented. A mutual inductance compensation circuit connected in series with each RF coil loop of the coil loop assembly substantially minimizes the coupling, or mutual inductance, that forms between the RF coil loops. The mutual inductance of the compensation circuit substantially equals, and is opposite in phase or polarity, to the mutual inductance that forms between the RF coil loops as the RF coil loops move or rotate with respect to each other.

摘要： A computer numeric control for metal forming which allows the automatic selecting of gauge position and ram position allowing both variables to act to produce bends in forming materials with different flange lengths and angles. The system also offers programming and calibration features comprising significant improvements over prior art apparatus and methods. The system integrates the press control circuitry and all precise control of flange length which can be programmed and offers precise control of the bend angle which can be programmed. Multiple programs can be stored and later retrieved. The apparatus can be calibrated in either English or metric units. Magnetic cassettes and printers can be utilized for permanent storage of programs and to produce permanent records on paper.
