Clockwise response-field

The EO behavior is also clearly chiral a clockwise response to a force applied perpendicular to the clock face, with a counterclockwise response to a force of opposite orientation. Furthermore, domains of opposite handedness can also be seen in these LC cells. That is, while the brushes in some domains rotate counterclockwise in response to an applied field of positive sign, other domains rotate clockwise in response to the same field. The EO behavior of a pair of such domains is enantiomorphous, implying that the domains themselves are heterochiral. 

When a particle and its antiparticle, such as an electron and a positron, or a proton and an antiproton, are used in head-on collision experiments, acceleration of the particles can be accomplished in one ring. This is because electrons and positrons, for example, behave m the same way in terms of their response to magnetic and electric fields. Thus, both particles can be injected into the same ring, one to follow an orbit in a clockwise direction the other in a counterclockwise direction. Upon injection of a cluster of each type of particle, collisions occur at two points diametrically opposed. This arrangement provides maximum utilization of the equipment.
