Novel small-angle collective Thomson scattering system.
A Thomson scattering opticals system is described with the following characteristics: (1) it allows scattering angles down to 1 mrad before collection optics interfere with beam dumping; (2) it gives excellent k resolution for angles of > or approximately 1.5 mrad; (3) it collects light from a scattering volume which can be variably positioned without optical realignment; and (4) it is compact ...
متن کاملSubterahertz gyrotron developments for collective Thomson scattering in LHD.
Collective Thomson scattering (CTS) is expected to provide the spatially resolved velocity distribution functions of not only thermal and tail ions but also alpha particles resulting from fusion reactions. CTS using gyrotrons with frequency higher than the conventional ones used for plasma heating would have advantages to alleviate refraction, cutoff effects, and background electron cyclotron e...
متن کاملNon-maxwellian Ion Velocity Distributions Observed Using Eiscat
Recent observations from the EISCAT neutral thermal speed. However, for larger incoherent scatter radar have revealed bursts of drifts the distribution function is predicted to poleward ion flow in the dayside auroral ionosbe highly non-Maxwellian and takes the form of a phere which are consistent with the ionospheric torus in velocity space (symmetric about the signature of flux transfer event...
متن کاملCollective Thomson Scattering Study Using Gyrotron in LHD
The collective Thomson scattering (CTS) is one of the most promising methods for evaluating the ion velocity distribution function. The study of CTS diagnostic has been started utilizing the gyrotron and antenna/transmission systems installed in LHD for high power local electron heating. One of the high power gyrotrons at 77 GHz is selected as a probing power source and a set of highly focused ...
متن کاملBenchmark and combined velocity-space tomography of fast-ion D-alpha spectroscopy and collective Thomson scattering measurements
Abstract. We demonstrate the combination of fast-ion D-alpha spectroscopy (FIDA) and collective Thomson scattering (CTS) measurements to determine a common best estimate of the fast-ion velocity distribution function by velocity-space tomography. We further demonstrate a benchmark of FIDA tomography and CTS measurements without using a numerical simulation as common reference. Combined velocity...
