Abstract
Collective Thomson scattering (CTS) system has been constructed at LHD making use of the high power ECRH system
in LHD. The necessary features for CTS, high power probing beams and receiving beams, both with well defined
Gaussian profile and with the fine controllability, are endowed in the ECRH system. The 32 channel radiometer with
sharp notch filter at the front end is attached to the ECRH system transmission line as a CTS receiver. The validation
of the CTS signal is performed by scanning the scattering volume. A new method to separate the CTS signal from
background ECE is developed and applied to derive the bulk and high energy ion components for several combinations
of NBI heated plasmas.
