The system for forming charged particles beams with small energy spread is proposed and studied. It is constructed on the basis of the Undulative Induction Accelerator (EH-accelerator). The obtained results of numerical modeling show that the proposed system allows to reduce the beam energy spread more than ~40 times. The mechanism of energy “equalization” of electrons during the accelerating beam is investigated. This mechanism is called the "effective cooling".
