The influence of the conditions of laser initiation on soft X-rays emission of vacuum spark

Abstract

Abstract. For exploring the influence of the conditions of laser initiation on soft x-ray emission of the laser-triggered vacuum spark we performed a series of experiments under different conditions of the laser beam focus on the cathode(anode) of the discharge system.

Micro-pinch formation and extreme ultraviolet emission of laser-induced discharge plasma*

“…[34] Although the Z-pinch plasma can reach a higher temperature, which is beneficial to the EUV production, micro-pinch plasma has its advantages, i.e., a relatively low energy injection and a more concentrated emission zone. [35] The small plasma size can reduce the optical depth and selfabsorption, so it is easier for EUV collection. [36] delay between laser and micro pinch in band EUV emission The formation of micro-pinch has more requirements for the parameters of laser.…”
