A target supplier accelerates a target material injected from a nozzle
such that a velocity of the target material after accelerated is kept
within a predetermined range. The target supplier includes: a target
nozzle that injects a target material in a liquid droplet state or solid
particle state; an electric charge supplying unit that supplies electric
charge to the target material; a charge amount measuring unit that
measures an amount of the electric charge supplied to the target material
by the electric charge supplying unit; a control unit that controls the
electric charge supplying unit in a feedback manner based on a
measurement result obtained by the charge amount measuring unit; and an
accelerator that accelerates the target material supplied with the
electric charge by the electric charge supplying unit.
