We present a novel design of a pulsed plasma discharge ion source for the creation of a vast variety of anions, especially hydrated water clusters. The ions are produced inside a glow discharge plasma and characterised via a Wiley-McLaren mass spectrometer. We report the successful creation of different species of anions from various gas compositions. In future experiments, the water clusters ions will be stored in a hybrid atom-ion trap for studies of chemical reactions at ultralow temperatures.
