TWP-W150 Microcomputer based Electrostatic Field Plotter Introduction: In engineering technology, it is often necessary to know the electric field distribution of the electrode system in order to study the movement of electrons or charged particles in the electric field. For example, in order to study the focusing and deflection of the electron beam in the oscilloscope tube, it is necessary to know the distribution of the electrode electric field in the oscilloscope tube. In the electron tube, it is necessary to study the influence of the introduction of new electrodes on the movement of electrons, and also to know the distribution of the electric field. In general, in order to obtain the distribution of electric field, analytical method and simulation experiment method can be used. However, only in a few simple cases can the electric field distribution be obtained analytically. For general or more complex electrode systems, the simulation experiment method is usually used. The disadvantage of the simulation experiment method is that the precision is not high, but for general engineering design, it can meet the requirements. This instrument is an integrated instrument with compact design and intuitive panel. The new method of using CCD camera for space positioning and software to describe electrostatic field is convenient to operate, and the measurement data is stable and reliable.
