Profile Optimization and High Beta Discharges and Stability of High Elongation Plasmas in the DIII-D Tokamak Open
The maximum experimental volume average toroidal beta in DIII-D scales with the plasma current divided by the plasma minor radius and the toroidal field, βT α I/aB. βT = 11% has been achieved at high normalized current by operating at high…

Achievement of ion temperatures in excess of 100 million degrees Kelvin in the compact high-field spherical tokamak ST40 Open
Ion temperatures of over 100 million degrees Kelvin (8.6 keV) have been produced in the ST40 compact high-field spherical tokamak (ST). Ion temperatures in excess of 5 keV have not previously been reached in any ST and have only been obtai…

Sparse representation of signals: from astrophysics to real-time data analysis for fusion plasmas and system optimization analysis for ITER and TCV Open
Efficient, real-time and automated data analysis is one of the key elements for achieving scientific success in complex engineering and physical systems, two examples of which include the JET and ITER tokamaks. One problem which is common …
