    Abstract: A radiation source includes an uncapped Mo/Si multilayer mirror, and a cleaning apparatus configured to remove a deposition comprising Sn on the uncapped Mo/Si multilayer mirror. The cleaning apparatus is configured to provide a gas comprising one or more of H2, D2 and HD and one or more additional compounds selected from hydrocarbon compounds and/or silane compounds in at least part of the radiation source, to produce hydrogen and/or deuterium radicals and radicals of the one or more additional compounds, from the gas, and to supply the hydrogen and/or deuterium radicals and radicals of the one or more additional compounds to the uncapped Mo/Si multilayer mirror to remove at least part of the deposition.
