Abstract
A discharge tube is assembled from three sections formed of metal. A first discharge tube element and a second discharge tube element are connected with an insulator for forming a discharging gap and vacuum-sealing interposed between connecting flanges of both discharge tube elements along with an O-ring. The first discharge tube element and a third discharge tube element and a third discharge tube element are connected in a similar manner, and a discharge gap is formed between adjacent discharge tube elements. A high-frequency power supply is connected to each discharge tube element. Respective discharge tube elements are provided with cooling medium flow paths separately each other.
