This patent describes a radiation detection apparatus for a FTIR spectrometer which is capable to receiving liquid coolant. It comprises: a detector having inner and outer vessels connected together to define a dewar, the inner vessel adapted to contain liquid coolant, the detector having a fill port extending from an outer surface of the detector to the interior of the inner vessel by which liquid coolant can be introduced in the inner vessel; a liquid coolant inlet port including a funnel having a top opening and extending to a bottom; a gas discharge prot including a funnel co-axial with, surrounding and spaced outwardly from the funnel of the liquid inlet port and extending from a top opening at substantially the same level as the top opening of the inlet port funnel to a bottom; a liquid delivery tube extending from the bottom of the inlet port funnel and into the inner vessel of the detector to deliver liquid coolant from the inlet port funnel to the interior of the inner vessel of the detector; a gas discharge tube co-axial with the spaced outwardly from the delivery tube and extending from connection with the detector at the fill port of the detector to the bottom of the gas outlet port funnel to direct gas resulting from evaporation of the liquid coolant in the inner vessel to the gas outlet port.
