Abstract

PURPOSE:To give flash light high brightness and stabilization by supressing a horizontal end-play of flash light basing on the fluctuation in a plasma state. CONSTITUTION:Magnets 5a and 5b are arranged while opposing together negative poles on the perphery of a tube body 1 and along the orbit of a flash light between the anode 2 and the cathode 3. As in this way the magnets 5a and 5b are opposingly arranged along the orbit of the flash light F, the flash light F is also to be sealed in a fixed position all over the orbit and accordingly, a horizontal end-play as in the case of the former xenon flash lamp can be checked thus giving the flash light high brightness and stabilization.
