Mechanical synchronous modulator for colliding beams

In order to increase the range of particle detection in crossed beam experiments, a mechanical synchronous modulator is proposed has an interrupter fitted with a fixer made in the form of a hollow cone with a 180 deg - αdeg angle at the vertex, where αdeg - stands for the angle of an angle intersection. The surface of the cone at its base and one of the sections perpendicular to its axis have each a row of modulation grooves. Such an interrupter design results in the scattering zone remaining outside the interrupter. This eliminates the effect of the walls of the interrupter on the scattered particles and allows the scattered particle detection range to be increased
