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, […]

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 […]

Solutions developed for housing ITER diagnostics


When the ITER experimental fusion reactor begins operation in the 2020s, over 40 diagnostic tools will provide essential data to researchers seeking to understand plasma behavior and optimize fusion performance. But before the ITER tokamak is built, researchers need to determine an efficient way of fitting all of these tools into a limited number of […]
