on the operation conditions considering that moderate electron temperature (below 800 keV) are desirable to favour shorter stabilization times. Using off-axis ECRH injection may also help to reduce L/R time. | on the operation conditions considering that moderate electron temperature (below 800 keV) are desirable to favour shorter stabilization times.

However, since both bootstrap and NBCD are contributing to the toroidal plasma current, the validation of NBCD needs first a numerical computation of the bootstrap contribution, ideally with a validated tool. | However, since both bootstrap and NBCD are contributing to the toroidal plasma current, the validation of NBCD needs first a numerical computation of the bootstrap contribution, ideally with a validated tool. |
