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

The transition radiation of a charged particle in the simplest case of incidence on an infinitely conductive, ideal plane can be described based on the well-known method of images from electrostatics. This method also enables finding the distribution of fields in more complex cases, such as the field of a point particle in the presence of two intersecting conducting planes, the angle between which divides the angle 180° evenly. Based on the method of images, we describe the transition radiation that occurs when a fast charged particle strikes a target consisting of two conducting half-planes intersecting at right angles (from the inside of a dihedral angle). The characteristics of radiation emitted by fast and slow particles are qualitatively examined, and their visual interpretation is given. The possibility of using interference effects arising from radiation for monitoring beams of charged particles is discussed.
