ASDEX Upgrade
Project
To make experiments under reactor-like conditions possible essential plasma properties, particularly the plasma density and pressure and the wall load, have been adapted in ASDEX Upgrade to the conditions that will be present in a future fusion reactor. This experiment is thus providing essential know-how for the ITER test reactor, which is to produce the first energy-yielding plasma.
The heating facilities for achieving the high plasma temperatures comprise max. 20 megawatts of neutral injection of atomic hydrogen or deuterium and 6 megawatts of radiofrequency heating, tunable between 30 and 120 MHz, and 4 megawatts of microwave heating at 140 GHz. The neutral beams of the two injectors are injected into the plasma through two large ports. The radiofrequency heating is coupled in through four integrated antennas, each powered by its own generator.
The plasmas are investigated with about 40 diagnostics. Some of the test data are already available for feedback control of the plasma after less than 10 milliseconds.
