Fusion diagnostics heat up across the US


Teams are developing tools to monitor and control ITER plasma ―Lynne Degitz  ITER, the world’s largest tokamak now under construction in France, will have over 60 diagnostic systems installed to enable plasma control, optimize plasma performance, and support machine protection¬. Princeton Plasma Physics Laboratory and Oak Ridge National Laboratory, in collaboration with industry and universities, […]

Building the heartbeat of ITER: Preparing a unique fabrication line for the central solenoid modules


―Lynne Degitz  With winding of the first production module for ITER’s central solenoid well underway, US ITER and its contractor, General Atomics, are now commissioning all of the necessary tooling stations for the 13 Tesla 1,000 metric ton electromagnet. Eleven unique stations will form the module manufacturing line at the GA Magnet Technologies Center, a […]

A 61,000-gallon drain tank manufactured by Joseph Oat Corporation in Camden, N.J. is part of the first shipment from the United States for the ITER tokamak cooling water system.

US delivers multiple “firsts” for ITER site


Conductor for toroidal field magnets, drain tanks and electrical components are being delivered to Europe for installation at the ITER site ―Lynne Degitz  As the international ITER magnetic fusion facility rises out of the ground in southern France, US ITER is ramping up hardware deliveries to Europe. In January, the United-States delivered its first batch […]

US ITER Diagnostics are poised to advance designs, place contracts


The United States has made important progress this fall to advance contributions to ITER international fusion experiment diagnostic instruments and port plugs. As of October 29, 2014, procurement arrangements governing all 11 US ITER diagnostic systems have been signed with the ITER Organization; these arrangements define and assign the design, procurement and delivery responsibilities for […]

Mitigating plasma disruptions in ITER: Using large cryogenic pellets, US ITER advances new fusion technology


The international ITER fusion project is building “a sun on earth” that will produce a self-heated, burning plasma—a key step toward industrial-scale fusion energy production. Controlling that plasma can be tricky, though, because disruptions may occur that cool and collapse the plasma. Sudden losses of plasma energy and current have the potential to erode plasma-facing […]

The 800-meter sample toroidal field conductor was transferred to a container ship at the port of Charleston, S.C., on May 28, 2014 for its voyage to La Spezia, Italy.

US ITER ships 30,000 pounds of magnet system hardware to Europe


An 800-meter length of sample toroidal field conductor is en route to La Spezia, Italy ―Lynne Degitz  ITER is a unique international scientific partnership that aims to demonstrate industrial-scale fusion power in the world’s largest experimental tokamak. An unusual aspect of the project is the often long and intricate journey some hardware components take from […]
