RF system for electron and positron orbit separation at VEPP-4M

The method for RF orbit separation of electron and positron beams in the VEPP-4M collider is developed and demonstrated. This system is designed to replace the conventional electrostatic orbit separator in the prospective CPT test experiment based on comparison of the spin precession frequencies of electron and positron. The electrostatic separator may yield an unacceptable systematic error of 10(-6) in the experiment against the required one of better than 10(-8) which can be provided with the RF system.
