摘要： The invention relates to vacuum tubes and especially to electron tubes. To produce the tube, and especially an electron collector comprising several electrodes, the electrodes are produced in the form of blocks of ceramic having a high thermal conductivity. The blocks are electrically conducting (at least on the surface). They are preferably made of an insulating ceramic such as aluminium nitride, and are made conductive over part of their surface. The conductive surface part is preferably formed by a conductive ceramic, preferably based on titanium nitride, or on similar conductive ceramic materials. Thus, increased strength, better heat dissipation and weight reduction are achieved.

摘要： A low-loss magnetic structure that provides an electron beam focusing field that can be accessed without field reversal. More specifically, the structure provides a uniform magnetic field that can be accessed from an adjacent field-free chamber within which an electron beam source of any size can be housed. The field-free chamber is separated from uniform field by a passive ferromagnet having a hole through which the electron beam can pass. The passive ferromagnet is instrumental in preventing the uniform field from entering the field-free chamber.

摘要： An electron collector is provided for collecting spent electrons generated by a charged particle device after passage though an interaction region of a RF circuit. The collector has a centerline and comprises an outer structure which is coupled to the RF circuit. An inner structure is within the outer structure, and receives the spent electrons. A negative voltage is applied to the inner structure, which forms an electric field between the inner and outer structures. A plurality of thermally conductive and electrically insulative standoff assemblies extend between the outer and inner structures. Each of the assemblies comprise a ceramic planar member centered within outer walls providing a double-ended cup shape, and conductive plugs which adjoin each side of the planar member with the respective one of the inner and outer structures. An axis of symmetry of the assemblies lies perpendicular to a radial vector extending from the centerline, and lies parallel to the electric field vector. Since the conductive plugs are partially surrounded by the outer walls, a relatively long surface voltage breakdown path is provided between the plugs, while the thermal path through the planar member is relatively short.

摘要： A PROCESS FOR THE PRETREATMENT OF COAL AND SIMILAR SOLIDS TWO-STAGE GASIFICATION FOR THE PRODUCTION OF A METHANE RICH GAS. THE COAL IS PRETREATED BY REACTING A BED OF FLUIDIZED COAL, OR A SLURRY OF COAL AND RECYCLED OILS, WITH A HYDROGEN RICH PRODUCT GAS AT TEMPERATURES MUCH LOWER THAN THOSE REQUIRED FOR HYDROGASIFICATION. THE PRETREATED COAL IS MIXED WITH STEAM AND REACTED IN A SECOND GASIFICATION STAGE WITH THE SYNTHESIS GAS PRODUCED IN THE FIRST GASIFICATION STAGE. THE REACTION IN THE SECOND STAGE PRODUCES CHAR ENTRAINED IN A HYDROGEN RICH PRODUCT GAS CONTAINING METHANE, WHICH PRODUCT GAS IS SEPARATED FROM THE CHAR AND IS PASSED THROUGH PURIFICATION REACTIONS AND METHANATED TO PRODUCE A METHANE RICH GAS. THE SEPARATED CHAR IS RECYCLED TO THE FIRST STAGE AND REACTED WITH STEAM AND OXYGEN TO PRODUCE THE SYNTHESIS GAS FOR THE SECOND STAGE. TEMPERATURES IN THE FIRST STAGE EXCEED 2500*F. AND TEMPERATURES IN THE SECOND STAGE EXCEED 1,600*F., WITH THE PRESSURE IN BOTH STAGES MAINTAINED IN EXCEED OF 50 ATMOSPHERES. THE COAL PRETREATMENT IS CONDUCTED IN A SINGLE STAGE OR IN MULTIPLE STAGES.

摘要： An efficient high power beam tube includes a gridded convergent flow electron gun for forming and projecting a beam of electrons through a centrally apertured accelerating anode to a fly-trap type depressed beam collector structure. A tapered conductive probe is axially disposed within the beam collector for cooperation with a collector focus electrode structure to shape the equipotentials at the mouth of the fly-trap beam collector, in the presence of space charge depression within the collector, such as to retain laminar electron flow and uniform current density transversely across the beam as the beam decelerates and expands into the beam collector structure, whereby increased depressed collector efficiency is obtained.

摘要： A charged particle collector comprising a stack of apertured electrode plates which lie within an imaginary sphere is provided. The plate closet to a charged particle emitter forms a portion of the imaginary sphere and is at zero volts potential with respect to the emitter. The plate farthest away from the charged particle emitter is of conical shape with the apex pointing toward the emitter and includes a spike extending toward the emitter. The conical plate has either a negative or positive potential with respect to the emitter, depending on whether the charged particles are negative or positive. A plurality of intermediate apertured electrode plates are positioned between the plate which forms a portion of the sphere and the conical plate, each of the plates being at a slightly lower potential than the preceding plate moving in a direction toward the emitter. These intermediate plates approximate the shape of an equipotential line which would be plotted for the particular voltage applied to the plate.
