'''Goal'''. We propose to explore the feasibility of measuring the phase relation between density and temperature fluctuations using a combined diagnostic based on Retarting Field Analyzer (RFA) and Langmuir probes that has been recently developed in the TJ-II stellarator. | '''Goal'''.

In addition, the unique capabilities of the dual HIBP system would allow the investigation of density and potential fluctuations in the TJ-II stellarator, from plasma core to plasma edge. Simultaneous, spatially overlapping, measurement of plasma parameters, using HIBP and electrostatic probes, would allow novel probe configurations [e.g. baffled probes] to be tested, and would provide plasma boundary conditions for HIBP calibration. | |||
