Electron Density Profile Reconstruction by Maximum Entropy Method with Multichannel HCN Laser Interferometer System on Spac 7

摘要

A multichannel HCN laser interferometer system has been developed to investigate the plasma electron confinement properties in a SPAC 7 device. The maximum entropy method is applied to reconstruct the electron density profile from measured line integrated data. Particle diffusion coefficient in the peripheral region of the REB ring core spherator was obtained from the evolution of the density profile.
