Relating to time-of-flight mass analysers

Abstract

The present invention relates to an apparatus for out-gassing to remove contaminants from surfaces within a vacuum chamber by heating and subsequently cooling the surfaces. The apparatus includes the vacuum chamber for housing a mass analyser. A heater is arranged to heat the surfaces within the vacuum chamber. One or more cooling channel(s) are present, in which the one or more cooling channels are arranged to cool the surfaces within the vacuum chamber by transporting a cooling medium through the one or more channel(s). An insulating material surrounds an outer surface of the vacuum chamber.
