摘要： When using micro-resonant structures, a resonant structure may be turned on or off (e.g., when a display element is turned on or off in response to a changing image or when a communications switch is turned on or off to send data different data bits). Rather than turning the charged particle beam on and off, the beam may be moved to a position that does not excite the resonant structure, thereby turning off the resonant structure without having to turn off the charged particle beam. In one such embodiment, at least one deflector is placed between a source of charged particles and the resonant structure(s) to be excited. When the resonant structure is to be turned on (i.e., excited), the at least one deflector allows the beam to pass by undeflected. When the resonant structure is to be turned off, the at least one deflector deflects the beam away from the resonant structure by an amount sufficient to prevent the resonant structure from becoming excited.
摘要翻译：当使用微谐振结构时，可以打开或关闭谐振结构（例如，当响应于改变的图像打开或关闭显示元件时，或者当通信开关被打开或关闭以发送数据不同的数据位）。不是打开和关闭带电粒子束，而是可以将光束移动到不激发谐振结构的位置，从而关闭谐振结构，而不必关闭带电粒子束。在一个这样的实施例中，至少一个偏转器被放置在带电粒子源和待激发的谐振结构之间。当谐振结构要被接通（即激励）时，至少一个偏转器允许光束通过未偏转。当谐振结构要关闭时，至少一个偏转器将光束从谐振结构偏离足以防止谐振结构被激发的量。

摘要： An electron gun comprises an electron emitter, an electrode surrounding the electron emitter, an extraction electrode, and a double condenser lens assembly, the double condenser lens assembly comprising a magnetic immersion pre-condenser lens and a condenser lens. In combination with a probe forming objective lens, the electron gun apparatus can provide an electron beam of independently adjustable probe size and probe current, as is desirable in electron beam applications. The electron emitter is immersed in the magnetic field generated by a magnetic type pre-condenser lens. When activated, the pre-condenser lens collimates the beam effectively to increase its angular intensity while at the same time enlarging the virtual source as compared with non-immersion case, due to geometric magnification and aberrations of its lens action. The pre-condenser lens is followed by a condenser lens. If the condenser lens is of the magnetic type, its peak magnetic field is far enough away and thus its action does not significantly affect the size of the virtual source. Independent adjustment of the lenses, combined with suitable selection of final probe forming objective aperture size, allows various combination of the final probe size and probe current to be obtained in a range sufficient for most electron beam applications.

摘要： A cathode ray tube (CRT) having a glass envelope is disclosed. The glass envelope is formed of a rectangular faceplate panel and a tubular neck connected thereto by a funnel. An electron gun is positioned in the neck for directing electron beams toward the faceplate panel. A yoke is positioned in the neighborhood of the funnel-to-neck junction. The yoke has windings configured to apply a horizontal deflection yoke field and a vertical deflection yoke field to the beams. At least one magnetic field sensor is located near the glass envelope for sensing an ambient magnetic field environment of the CRT. A controller receives a signal from the magnetic field sensor. Register correction coils are mounted in the vicinity of the neck and are dynamically controlled by the controller to shift the beams. Quadrupole coils are applied to the neck and have adjacent poles of alternating polarity such that the resultant magnetic field being dynamically controlled by the controller based on the magnetic field sensor signal moves outer ones of the beams to correct the misconvergence caused by the register correction.
