Real-time determination of suprathermal electron local emission profile from hard X-ray measurements on Tore Supra

The Tore Supra tokamak is well adapted to sustain long-duration noninductive discharges using the lower hybrid (LH) heating and current drive as the main power source. In these conditions, the LH power deposition profile is strongly linked to the current density profile and can be deduced from the hard X-rays (HXRs) measurements which are produced by the suprathermal electrons generated by the abs...
