A beam of charged particles is scattered by a thin foil (16) 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 DEG , 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 (10) for stabilizing the beam energy and/or providing an energy interlock. |
