| 摘要 |
An electromagnetic radiation transmitter/reflector device (1), an apparatus and a method using said device are disclosed. The device includes a straight transparent quartz tube (2) with an end-to-end bore (3) extending therethrough along an axis (4) for retaining a pressurised ionising gas and defining the cross-section of the radiation transmitter beam, as well as a surface (7) for reflecting the transmitted radiation, which surface comprises two longitudinal side wings (14) that are symmetrical in relation to an axial plane (10) of the bore. Said reflective portion is at least partially secured to the tube. |
