METHOD AND DEVICE FOR VISUALIZING IMAGES OF CHARGED-PARTICLE EMITTING OBJECTS Russian patent published in 2003 - IPC

FIELD: electronic devices including emitting video devices. SUBSTANCE: method for visualizing images of analyzed objects emitting charged particles by means of recorder involves restriction of their transversal displacement by building up magnetic field in working area of particle motion from object to recorder. Magnetic field is built up so that it uniformly rises in working area from analyzed object toward recorder. Device implementing this method has hollow multiturn coil for building up gradually rising magnetic field in working area, analyzed object fastening member or fastening unit for holding device in position in front of analyzed object surface, and recorder. Coil has number of ampere-turns rising from object toward recorder. Magnetic system may be made either in the form of solenoid or as residual-magnetization rod. Proposed transport magnetic systems provide for rising magnetic-field structure in working area in the from of small-curvature lines of force converging relative to longitudinal axis of device. Working area between analyzed object and recorder is shaped as truncated cone where analyzed object and its fastening member are disposed at larger-section cone base and recorder is installed at smaller-section cone base. EFFECT: enlarged areas of analyzed object images obtained. 6 cl, 2 dwg
