(a) Front and side views of the probe head (schematic), (b) top view of the Aditya tokamak showing toroidal separation between the limiter and the probe head.
The I-V characteristic of the unmagnetized probe. The fitted line indicates , where a = 0.812, b = −0.049, and c = −0.412 and the regression coefficient, R-square = 0.99.
(a) Radial profile of electron temperature measured by a Langmuir probe mounted on the top port in discharges similar to the presented ones; (b)floating potential profile in identical discharges.
Schematic diagram showing plasma position (exaggerated). The probe positions (on both radial and top ports) are fixed with respect to the limiter, but plasma positions in different discharges may be different.
(a) Radial profile of mean plasma densities measured by the Mach probe at radial port, and (b) radial profile of plasma density measured by the single Langmuir probe at the top port. The error bars indicate the scatter in the data.
(a) Radial profile of the Mach numbers, and (b) dependence of Mach numbers on the mean plasma density. The error bars indicate scatter in the data.
Schematic diagram of Aditya SOL flows. “R” and “T” indicate physical locations of Mach probe on the radial and top ports respectively and “Measured” indicates the measured flow direction. The hatched lines indicate two faces of the limiter and “Plasma contact point” indicates the contact of the plasma LCFS with the limiter [see Fig. 4 ]. Note that the connection length at the top probe is as explained.
