LTCalcoli is pleased to announce the publication of a new scientific paper showcasing a multidisciplinary optimisation strategy for the Thermal Shield of the Volumetric Neutron Source (VNS)—a key facility for advancing fusion nuclear technology. 

The study presents an integrated approach combining electromagnetic, thermal, and structural analyses to enhance the performance and reliability of the VNS Thermal Shield. This component is essential for protecting superconducting magnets and cryogenic systems by limiting heat transfer from hotter regions of the tokamak. 

The research explores multiple design iterations aimed at reducing electromagnetic forces during magnet charge and discharge cycles. By introducing targeted cuts, reinforcements, and evaluating advanced aluminium alloys and composite materials, the team optimised both rigidity and weight while ensuring robust structural integrity. 

A dedicated thermal study was also conducted to maintain the shield at around 80 K, incorporating cooling channels to improve temperature uniformity and reduce thermal gradients. 

The results demonstrate that innovative material choices and integrated design strategies can significantly improve the shield’s thermal and mechanical behaviour, reinforcing the importance of the VNS as a platform for validating critical fusion technologies under realistic operating conditions. 

With this work, LTCalcoli confirms its leadership in advanced simulation and engineering solutions for next-generation fusion systems.
