Description
The design of highly controlled sample environments is a critical engineering challenge for the successful operation of modern neutron scattering facilities. The Argentine Neutron Beam Laboratory (LAHN), currently under construction, will host the Advanced Neutron Diffractometer for Engineering and Science (ANDES). This instrument is designed to characterize the crystallographic structures of a wide range of materials, including metals, ceramics, polymers, and soft matter. To meet diverse scientific requirements, ANDES demands a versatile sample chamber capable of maintaining precise environmental conditions, including controlled gas flow, pressure, temperature, and relative humidity.
In this work, we present the preliminary thermal analysis of the ANDES sample chamber design, conducted using Ansys® finite element simulation software. The primary objective is to evaluate the steady-state and transient thermal behavior of the chamber under various operational conditions. Through these simulations, we aim to optimize the chamber's geometry and material selection to ensure that the sample reliably reaches target temperatures. Furthermore, the analysis focuses on guaranteeing the structural integrity of the components, mitigating unwanted thermodynamic effects (such as severe thermal gradients), and minimizing background scattering to ensure optimal neutron transmission.
