IN-LINE ELECTRON BEAM ENERGY MONITOR AND CONTROL

摘要

13 A beam of charged particles is scattered by a thin foil and the flux at two angles, .theta.1 and .theta.2, is sampled to yield an exponential function of the respective energy difference, E(.theta.2) - E.theta.1). For .theta.1 = 0.degree., a signal representative of the energy stability of the beam is obtained and compared with a reference to form an error signal for application to the accelerator for stabilizing the beam energy and/or providing an energy interlock.
