Electron density diagnostics by Fe XXII line intensity ratio
The electron density of a tokamak plasma is obtained from the 114.41 and 117.17Å line intensities of Fe XXII. This measurement is found to be useful for electron densities in the range 1012−1015 cm−3, on account of its weak dependence on temperature and of the proximity of these spectral lines.
期刊介绍：
Physics Letters A offers an exciting publication outlet for novel and frontier physics. It encourages the submission of new research on: condensed matter physics, theoretical physics, nonlinear science, statistical physics, mathematical and computational physics, general and cross-disciplinary physics (including foundations), atomic, molecular and cluster physics, plasma and fluid physics, optical physics, biological physics and nanoscience. No articles on High Energy and Nuclear Physics are published in Physics Letters A. The journal''s high standard and wide dissemination ensures a broad readership amongst the physics community. Rapid publication times and flexible length restrictions give Physics Letters A the edge over other journals in the field.
