Max Planck’s ELISE reaches record values for ITER plasma heating

Posted by in category: particle physics

To do this, hydrogen ions are first generated, extremely accelerated in an electric field, and then neutralized to enter in the magnetic cage of the ITER tokamak where the plasma is confined. Such a powerful NBI heating—two particle beams are to deliver 16.5 megawatts each—has never been built before.

The aim of the Max Planck ELISE experiments is to generate a hydrogen ion beam with a reliably high current density and demonstrate quasicontinuous operation. The ion source of ELISE is half the size of the ion source for ITER.

What it means: The record ion current density means that ELISE has already achieved the ITER target, even though only a maximum of 75 percent of the high-frequency power available at ITER is available to generate the ion source plasma at the experimental testing facility.
