Building the Heart of ITER
A new computer simulation helps explain the existence of puzzling supermassive black holes observed in the early universe. The simulation is based on a computer code used to understand the coupling of radiation and certain materials. "Supermassive bl
ack holes have a speed limit that governs how fast and how large they can grow," said Joseph Smidt of the Theoretical Design Division at Los Alamos National Laboratory. "The relatively recent discovery of supermassive black holes in the early development of the universe raised a fundamental question, how did they get so big so fast?" Using computer codes developed at Los Alamos for modeling the interaction of matter and radiation related to the Lab's stockpile stewardship mission, Smidt and colleagues created a simulation of collapsing stars that resulted in supermassive black holes forming in less time than expected, cosmologically speaking, in the first billion years of the universe. US ITER, with General Atomics and other industry partners, is now fabricating the heart of the ITER tokamak: The 60 foot tall central solenoid. This massive electromagnet will initiate and maintain plasma current in the international ITER fusion reactor now under construction in France. ITER is the first fusion device designed to produce a burning plasma--an essential step for fusion energy development. This short offers an inside view of the action at the GA Magnet Technologies Center in California where the central solenoid modules are being produced.
