Hydrogen as an impurity in deuterium discharges has been studied using three different experimental methods on a pulse by pulse basis over seven months of JET operation as well as regarding its behaviour during single pulses. Evidence concerning the primary sources and the dynamics of recycling and removal of hydrogen has been obtained. A transient enrichment of hydrogen in high performance plasmas has been found and studied.
