Model-based estimation of tokamak plasma profiles and physics parameters: algorithm overview and application to ITER

Nuclear Fusion
Combining dynamic models and measurements into a consistent plasma state estimate is an important challenge for ITER and DEMO, due to the inherent limitations regarding diagnostic coverage in a nuclear fusion reactor environment.

Full radius integrated modelling of ohmic ramp-up at TCV including self consistent density prediction

Nuclear Fusion
The ramp-up is a critical phase in the operations of a Tokamak, during which engineering and physics aspects must be taken into account to ensure stability, minimize flux consumption and avoid disruptions.

Predictive integrated modelling of the hybrid and baseline scenarios of JT-60SA in view of the second operational phase

Nuclear Fusion
The integrated modelling of two plasma scenarios, hybrid and baseline, envisaged for the second operational phase (OP2) of the JT-60SA tokamak has been performed using the 1.5-dimensional JINTRAC suite of codes and the Bohm/gyro-Bohm (BgB) semi-empirical

Detection of alpha heating in JET-ILW DT plasmas by a study of the electron temperature response to ICRH modulation [PDF]

In the JET DTE2 campaign a new method was successfully tested to detect the heating of bulk electrons by α-particles, using the dynamic response of the electron temperature T e to the modulation of ion cyclotron resonance heating (ICRH).

Control of the hydrogen : deuterium isotope mixture using pellets in JET [PDF]

, 2019
Deuterium pellets are injected into an initially pure hydrogen H-mode plasma in order to control the hydrogen: deuterium (H:D) isotope mixture. The pellets are deposited in the outer 20% of the minor radius, similar to that expected in ITER, creating ...
