A gas inlet (), in particular for use in an ion thruster, comprises a housing () which is made of a gas-tight ceramics material and which is provided with a first gas feed channel () and a second gas feed channel () arranged downstream of the first gas feed channel (). The gas inlet () further comprises an insert () which is arranged in the second gas feed channel () and is made of a porous ceramics material, wherein the geometry and pore structure of the insert () are such that the insert () forms a desired flow resistance for a gas stream flowing through the second gas feed channel () which is greater than a flow resistance acting on a gas stream flowing through the first gas feed channel (), and wherein a ratio of a length () of the first gas feed channel () to a length () of the insert () is at least 1:2.
