Abstract
An electron beam detection device () is arranged on an electron beam passing path so that a beam delay time tfrom a passing moment of an electron beam () to a moment when the beam reaches a predicted collision point () is longer than a laser delay time tfrom a moment when a command for generating laser light () is issued to the moment when the laser light reaches the predicted collision point () by at least a predetermined delay time Δt. The device () may detect passing therethrough without affecting the electron beam and output a laser light generation command from a laser light command delay circuit () when the predetermined delay time Δt (=t−t) has elapsed after the detection.
