The Fusion Device Information System (FusDIS), developed and maintained by the IAEA, focuses on fusion devices worldwide. FusDIS contains information on fusion devices public or private with experimental and demonstration designs, which are currently in operation, under construction or being planned, as well as technical data of these devices and country statistics, including research statistics from the Fusion Energy Conference series. All information is collected by the IAEA and undergoes a process of review involving the International Fusion Research Council
