OPTIMAL BEAMLINES FOR BEAMS WITH SPACE CHARGE EFFECT

Space charge effect is ever of fundamental importance for low-energy parts of accelerators. Simple and robust estimations of the emittance degradation in various space charge affected beamlines have been obtained analytically and numerically. Nonuniform longitudinal and transverse distributions of current, accelerating and bunching were taken into account. The parameters of optimal beamlines for space charge affected beams have been estimated
