In an effort to put the world's largest scientific experiment back on track after delays and cost overruns, Europe is shaking up the agency overseeing its portion of the multinational ITER reactor.rnOn 16 February, Frank Briscoe, a British fusion scientist, will take the reins as interim director of Fusion for Energy (F4E), the agency in Barcelona, Spain, that manages Europe's ITER contribution - the largest of any partner's. Briscoe replaces Didier Gambier, a French physicist who joined the F4E as director when it formed in 2007. Gambier was originally appointed for a five-year term.rnThe European Union (EU) is also formulating a plan to complete construction on the multibillion-dollar machine in 2019, a year after currently scheduled, Nature has learned.rnITER aims to prove the viability of fusion power by using superconducting magnets to squeeze a plasma of heavy hydrogen isotopes to temperatures above 150 million ℃. When full-scale experiments begin in 2026, the machine should produce ten times the power it consumes.
