Title: Measurements Of Plasma Edge Electron Temperature And Density Using Visible Spectroscopy In Nova-unicamp Tokamak
Author: Do Nascimento F.

Abstract: The electron temperature (Te) and density (ne) at the edge of NOVA-UNICAMP tokamak plasma were determined along the discharge using the concept of particle confinement time (τP) uniqueness and spectroscopic measurements of hydrogen Balmer series emissions. We have used three absolutely intensity calibrated spectrometers with photomultipliers for simultaneous measurements of hydrogen alpha, beta and gamma emissions throughout the discharges. With the use of data from Johnson and Hinnov's table, we have performed an interactive method to find electron temperatures and densities that satisfy the τP uniqueness to obtain the temporal evolution of Te and ne parameters. The results achieved are in agreement with the expected values for these parameters at the edge of the NOVA-UNICAMP tokamak plasma.
