The radial tunable periodic cusped magnet (RTPCM) focusing system is designed in this paper. It is shown that a radial divergent sheet beam with 1800V, 84.9mA can be transported smoothly through the drift tunnel with height of 0.36mm and length of 18.8mm focused by this RTPCM system.
The radial divergent sheet beam electron optical system focused by a radial uniform magnetic field is designed in this paper. It is shown that the radial divergent sheet beam with size of 8 deg×0.23 mm, generated by the electron gun with 1700V, 151 mA, can stably pass through the beam drift tunnel with transverse size of 20 deg×0.52 mm and the length of 20 mm in a radial quasi-uniform magnetic field.
A new current transformer based on planar air core coil was presented in this article. The secondary coil of sensor was implemented on printed circuit boards and each PCB contains two coils in opposite directions to eliminate the impacts of outside magnetic field by the greatest degree. Moreover, multilayer boards were connected to improve mutual inductance. The PCBs were embedded in the primary coil...
This paper proposes a new type of display system Electron Beam Plane Display Panel (for short EBPDP). Its working principle is different from the traditional CRT. EBPDP uses the refraction field as frame scan, uses the correction plate to correct arc grating and fan-shaped aberration, and uses the zoom electron gun to focus electron beam. The process is simple and easy to implement. In aspects of...
