摘要： An X-ray tube with a rotating, motor-driven anode made up from a disc of graphite covered on a major portion of its convex surface which is turned away from its axis of rotation by a layer of an X-ray emissive refractory metal or alloy which has a much lower coefficient of thermal emissivity than the other face of graphite. To reduce thermal radiation in the direction of the rotor to which the anode is secured, the X-ray emissive, convex, covered surface of the anode, which is subjected to electron bombardment, is turned toward the rotor and the cathode lies on the same side of the anode as the rotor of the driving motor, resulting in reduced operational temperatures of these parts. Additional thermal protection for the rotor and bearing is afforded by providing a reflective surface on the rotor or by installing a protective disc-shaped shield between the rotor and the anode. The reduced temperatures of rotor and bearing permit increased output power and lengthened operating periods of the X-ray tube. In addition, a coolant may be circulated through the hollow anode shaft to further reduce the bearing temperatures.
摘要翻译：一种具有旋转的电动机阳极的X射线管，其由覆盖在其凸形表面的主要部分上的石墨盘构成，其通过X射线发射难熔金属层离开其旋转轴线，合金的散热系数比石墨的另一面低得多。为了减少阳极固定在转子方向上的热辐射，经受电子轰击的阳极的X射线发射凸面覆盖表面转向转子，阴极位于相同的位置作为驱动电动机的转子的阳极侧，导致这些部件的工作温度降低。通过在转子上提供反射表面或通过在转子和阳极之间安装保护性盘形屏蔽来提供转子和轴承的附加热保护。转子和轴承的温度降低允许增加输出功率和延长X射线管的工作周期。此外，冷却剂可以通过中空阳极轴循环，以进一步降低轴承温度。

摘要： A rotating anode for an X-ray tube is constructed with a broad rim on to which the radiation - exciting electron beam is focused from a direction perpendicular to the axis of rotation. In order to distribute the thermal loading over the surface of the rim a transverse scanning motion is applied to the electron beam. Viewing the source conventionally from a direction nearly parallel to the axis of rotation the scanning spot is required to appear stationary and this is achieved by forming the surface of the anode rim in a uniform pattern of transverse channels. The scanning waveform must conform generally to the cross-section of the channels and the frequency and phase of the scanning motion must bear a defined relationship to the rate of rotation of the channel pattern.
摘要翻译：用于X射线管的旋转阳极被构造成具有宽边缘，辐射激发电子束从垂直于旋转轴线的方向聚焦在该边缘上。为了将热负荷分布在边缘表面上，横向扫描运动被施加到电子束。通常从几乎平行于旋转轴的方向观察源，扫描点需要显示为静止的，这通过以横向通道的均匀图案形成阳极边缘的表面来实现。扫描波形通常必须符合通道的横截面，扫描运动的频率和相位必须与通道图案的旋转速率保持一定的关系。

摘要： Electron emissive device such as an x-ray tube having a cathode for generating electrons and an anode for receiving the same is provided with an auxiliary electrode insulated from the focusing cup electrode and positioned behind the cathode filament. A positive potential may be applied to such auxiliary electrode relative to the filament so that such auxiliary electrode attract electrons and prevent their flow to the anode.
