    摘要： A method for controlling beam quality degradation from ISR and CSR and stabilizing the microbunching instability (μBI) in a high brightness electron beam. The method includes providing a super-periodic second order achromat line with each super period being individually linearly achromatic and isochronous, setting individual superperiod tunes to rational fractions of an integer (such as 4th or 6th integers), setting individual bend angles to be as small as practical to reduce driving terms due to dispersion and dispersive angle, and setting bend radii as large enough to suppress ISR but not negatively affect the radial dependence of CSR. The method includes setting the structure of the individual superperiods to minimize bend plane beam envelope values in the dipoles to reduce betatron response to a CSR event at a dispersed location, increasing beam angular divergence, and creating dispersion nodes in the dipoles to similarly reduce response to CSR events, and limit R56 modulation in order to mitigate μBI.

    摘要： There are provided CRT display systems. A CRT display system includes an electron gun assembly, a single plane sheath beam bender, and a digital processor. The electron gun assembly is configured to emit electron beams. The single plane sheath beam bender is configured to apply a deflection force to the electron beams. The digital processor is configured to receive and process an incoming video signal stream to provide signals there from to be delivered to individual cathodes of the electron gun assembly. The provided signals have a distortion applied thereto to effect a predetermined converged image. The applied distortion at least relates to a blue-bow convergence error.

    摘要： On an outer circumferential surface of a neck portion of a funnel, a CPU having a pair of quadrupole magnets and a pair of bar-shaped magnets each having magnetic poles on both sides in a major axis direction are provided. The pair of bar-shaped magnets sandwich the neck portion substantially in an in-line direction of an in-line type electron gun, and are provided so that identical poles are opposed to each other, between an end plate of an insulating frame of a deflection yoke and the CPU at a distance from the end plate. In the case where a rotational shift of electron beams is caused, electron beams R and B are corrected so as to move upward and downward (or downward and upward) respectively by a quadrupole magnetic field generated by the quadrupole magnets. Then, the electron beams R and B are corrected so as to move downward and upward (or upward and downward) respectively by the quadrupole magnetic field generated by the pair of bar-shaped magnets. Thus, a misconvergence due to the rotational shift of the electron beams can be corrected.

    摘要： A compensating circuit is for compensating distortion of a picture which is displayed on a display unit having a yoke. The compensating circuit controls a yoke current to compensate a picture distortion. The compensating circuit comprises a first generating section for generating a digital deflecting compensation signal in accordance with deflecting compensation data representative of compensation value of the picture. A second generating section generating a variable voltage (+B voltage) in accordance with a PWM pulse signal to control the yoke current on the basis of the variable voltage. A peak holding circuit holds a peak voltage of a flyback pulse based on the variable voltage to produce a peak voltage signal representative of the peak voltage. An A/D converter circuit converts the peak voltage signal into a digital peak signal. A PWM section produces the above-mentioned PWN pulse signal in accordance with the digital deflecting compensation signal and the digital peak signal.
