R-500 Flight tube


The flight tube is a stainless steel tube with conflat ports for the reflectron vacuum vessel, the detector assembly, a pump (not supplied), the extraction and octopole lens assembly and a spare. The ports are tilted so that the ion beam passes down the optical axis of the extraction lens and is then directed at a small angle to the reflectron normal. This allows the outgoing and returning ions to be separated, making room for the detector. By using the reflectron rather than deflector plates distortion in the ion beam is minimised.
