Transition Radiation on a Conducting Target Shaped as a Right Dihedral Angle

The transition radiation of a charged particle in the simplest case of its incidence onto an infinite, perfectly conducting plane can be described using the method of images known from electrostatics. The same method makes it possible to find the field distribution in more complex cases, such as the field created by a point particle in the presence of two intercepting conducting planes, the angle between which divides exactly the angle of 180°. Based on the method of images, a description is given of the transition radiation that occurs when a fast-charged particle falls on a target in the form of two conducting half-planes intersecting at the right angle (on the inside of the dihedral angle). The features of the radiation emitted by fast and slow particles are qualitatively considered, and their visual interpretation is given. The possibility of using interference effects arising from radiation to monitor beams of charged particles is discussed.
