Abstract
A method for direct momentum correction of a selected beam particle using a controllable induction-voltage modulator is proposed for a low-flux ion beam. The corrected ion beam has a small momentum error restricted by a detection error at a kinetic energy analyzer and a voltage fluctuation at the induction-voltage modulator. Numerical simulations indicate that the scheme using a multiturn correction in a storage ring can considerably reduce the requirement of the amplitude and the tolerance level of the correction voltage. The results also show the final momentum error of the order of can be rapidly achieved at total flight time of when repetitive correction voltages are applied during the revolutions in the ring.
