Abstract

This report concerns the injection of lower hybrid (LH) wave power at 8 GHz into IGNITOR shear reversal scenarios, characterized by a reduced plasma current and density. Power deposition calculations are performed to establish whether LH waves can be used both as central heating and an off axis current drive tool. It turns out that LH waves can be used:

- For central plasma heating purposes during the current vamp phase, to freeze the shear reversed configuration, at the power level of approximately 10 MW.
- To drive a current in the outer part of the plasma at the power level of 20 MW. In this way between one sixth and one third of the total current in the proper plasma position is driven.
