摘要： An X-ray tube (100) comprises a rotor shaft (106); a rotor seat (108), which is an integral structure, electrically conductive and thermally insulating, and connected to the rotor shaft in a fixed manner; a bearing (104), which is connected in a fixed manner to the rotor seat. The X-ray tube increases the radiative cooling capability of the anode, and reduces the thermal effect on the rotor and bearing. The anode can be used at a high temperature, so that the entire anode can be made of TZM molybdenum alloy with no need for graphite brazing. Compared with X-ray tubes having fixed-anode, the X-ray tube has a relatively high short-time pulse power and small size, and compared with large-size rotary tubes, has a relatively high continuous power.

摘要： Portable x-ray devices and methods for using such devices are described. The devices have an x-ray tube powered by an integrated power system. The x-ray tube is shielded with a low-density insulating material containing a high-Z substance. The devices can also have an integrated display component. With these components, the size and weight of the x-ray devices can be reduced and the portability of the devices enhanced. The x-ray devices also have an x-ray detecting means that is not structurally attached to the device and therefore is free standing. Consequently, the x-ray devices can also be used as a digital x-ray camera. The portable x-ray devices are especially useful for applications where portability is an important feature such as in field work, remote operations, and mobile operations such as nursing homes, home healthcare, or teaching classrooms. This portability feature can be particularly useful in multi-suite medical and dental offices where a single x-ray device can be used as a digital xray camera in multiple offices instead of requiring a separate device in every office.

摘要： An integral cathode (200) for use with x-ray devices (102). The integral cathode (200) includes an emitter (202) made of a refractory metal such as tungsten, preferably doped with rhenium to afford malleability during constructions and assembly. The integral ctahode (200) also includes a support cartridge (204), preferably composed of an electrically non-conductive material such as ceramic, in which the emitter (202) is received. The support cartridge (204) electrically isolates the cathode (200) from the other components and structures of the x-ray device (102). Additionally, the support cartridge (204) serves to impose, and maintain, a parbolic curve in the emitter (202). The parabolic form of the emitter (202) naturally shapes an electron beam by causing electrons discharged from the emitter to converge at a focal spot (106). In this way, both the emission and focusing functions of the cathode (200) are integrated and performed by a single part.

摘要： The present invention relates to an X-ray tube structure for obtaining a high anode current output within a predetermined range of working voltages. The anode current output can be increased by neutralising the negative volumetric charge of the electrons emitted by the cathode using the positive ions from a gas which is inert relative to the cathode material. The positive ions are generated in the cathode-anode gap of the X-ray tube by the ionising interaction between the flow of electrons and the gas molecules moving from the cathode to the anode. The X-ray tube of the present invention includes a cathode and an anode arranged in a working volume filled with a gas which is inert relative to the cathode material at a pressure of up to (0.001 DIVIDED 0.5)P. The pressure P is selected in the left branch of a Paschen's curve according to the maximal voltage value at the anode and to the cathode-anode distance of the X-ray tube. This structure provides for a high anode current output, can be easily manufactured and also increases the service duration of the cathode and the anode due to the convection cooling mechanism in the rarefied gas, which is particularly important during pulse-mode operation.

摘要： A laser plasma X-ray generator which has a high X-ray conversion efficiency and produces little debris, a semiconductor aligner using the generator and a semiconductor exposure method are disclosed. In the laser plasma X-ray generator, the target to be irradiated with a laser beam is a metal oxide. The semiconductor aligner comprising such a laser plasma X-ray generator is characterized by further comprising a collecting mirror which directs X-rays generated by the plasma X-ray generator to a mask, and an X-ray convergence exposure mirror which converges the X-rays reflected by the mask and projects the X-rays onto a semiconductor wafer. In the semiconductor exposure method, X-rays generated by a laser plasma X-ray generator where the target is a metal oxide are collected, applied to a mask, and reflected by the mask, the reflected X-rays are converged, and a semiconductor mask pattern is projected onto a semiconductor wafer to expose it.
