We present Citlalmitl (the word for meteorite in the Nahuatl language), a new experimental device designed and built to simulate high-temperature processes relevant for meteoritics, including chondrule formation and the atmospheric entry of micrometeorites (MMs). The main component of Citlalmitl is a 50 W CO 2 laser, used to melt samples that simulate the precursors of meteoritical materials. As examples of the operation of our device, we have irradiated silicate samples controlling the laser duty cycle to reproduce heating profiles predicted by shock-wave simulations. Citlalmitl records the sample temperature during and after irradiation, a unique feature that allows us to directly measure the thermal history of the sample, a key parameter for the characteristics observed in MMs and chondrules. We demonstrate that Citlalmitl can reproduce different heating profiles useful to mimic thermal histories in meteoritical processes.

Citlalmitl：具有任意热历史的基于激光的气象样品制造设备

我们介绍Citlalmitl（纳瓦特尔语中的陨石一词），这是一种设计和制造用于模拟与气象学有关的高温过程的新实验设备，包括软骨形成和微陨石（MMs）的大气进入。Citlalmitl的主要成分是50 W CO 2激光器，用于熔化模拟气象材料前体的样品。作为我们设备操作的示例，我们已照射了控制激光工作周期的硅酸盐样品，以再现通过冲击波模拟预测的加热曲线。Citlalmitl记录辐照期间和辐照后的样品温度，这一独特功能使我们能够直接测量样品的热历史，这是在MM和软骨中观察到的特性的关键参数。
