摘要:

在LISA Pathfinder(LPF)上进行的热实验将提供仪器与温度变化相关性的基本信息。必须对这些热实验进行建模和模拟,以便为飞行任务操作目的进行验证,并开发一种能够消除温度噪声对仪器性能影响的数据分析工具。在这里,我们将介绍开发的模型和模拟信号的一些实验以及相应的干涉仪读数,后者是通过结合热模型与全球LTP(LISA技术包)的LTP数据分析团队的模拟器计算。

英文摘要:

The thermal experiments to be carried out onboard LISA Pathfinder (LPF) will provide essential information of the dependences of the instrument with respect to temperature variations. These thermal experiments must be modelled and simulated both to be validated for mission operations purposes and also to develop a data analysis tool able to characterise the temperature noise contribution to the instrument performance. Here we will present the models developed and the simulated signals for some of the experiments together with the corresponding interferometer readouts, the latter being computed by combining the thermal models with the global LTP (LISA Technology Package) simulator of the LTP Data Analysis team.
