The effect of gas temperature on the transport of the CO2+ ion in its parent gas CO2 is studied. For this purpose, a Monte Carlo (MC) solution technique of the ion transport equation developed in the past by the authors, which was formally proven to provide the exact solution of the transport equation, is used. The study is performed first by benchmarking against experimental data and another MC code, using cross sections from literature and then changing the gas temperature. The solution is characterized through its moments such as reduced mobility, coefficients of its expansion in Legendre polynomials and three-dimensional ion velocity distribution function. It is shown that the gas temperature has a significant effect on all these quantities. This finding has important consequences for plasma modeling which are discussed.

气体温度对CO的影响₂ ⁺在CO离子迁移₂

研究了气体温度对其母气 CO2 中 CO2+ 离子传输的影响。为此，作者使用了过去开发的离子传输方程的蒙特卡罗 (MC) 求解技术，该技术已被正式证明可以提供传输方程的精确解。该研究首先通过对实验数据和另一个 MC 代码进行基准测试，使用文献中的横截面，然后改变气体温度来进行。该解的特征在于其矩量，例如降低的迁移率、其在勒让德多项式中的膨胀系数和三维离子速度分布函数。结果表明，气体温度对所有这些量都有显着影响。这一发现对讨论的等离子体建模具有重要意义。
