High-resolution spectra emitted by laboratory plasmas provide invaluable diagnostic tools for the measurement of plasma properties. To be implemented, they require a large amount of atomic data and transition rates, which are available in several spectral codes. In this paper we present a new feature added to the CHIANTI code, which allows us to calculate the Zeeman splitting of spectral lines in the presence of a magnetic field with known intensity and orientation. When combined with the CHIANTI database and software to calculate level populations and line emissivities, this new feature returns the emissivities in all four Stokes parameters, that can be utilized for the measurement of the magnetic field inside laboratory plasma chambers, along with other plasma parameters. This new feature can be applied to the analysis of the emission of laboratory plasmas created in different devices.

CHIANTI中塞曼分裂的介绍

实验室等离子体发射的高分辨率光谱为测量等离子体特性提供了宝贵的诊断工具。要实施，它们需要大量的原子数据和转换速率，这些数据可以在几种光谱代码中获得。在本文中，我们提出了一个添加到 CHIANTI 代码的新功能，它允许我们在存在已知强度和方向的磁场的情况下计算谱线的塞曼分裂。当与 CHIANTI 数据库和软件结合以计算能级群和线发射率时，这一新功能会返回所有四个斯托克斯参数的发射率，可用于测量实验室等离子体室内的磁场以及其他等离子体参数。
