About Paper:

The high luminosity upgrade for the Compact Muon Solenoid detector at CERN - LHC will push the limits of structural support materials with high radiation environment and the need for robust cooling. The detector support structure consists of a composite cross-section that acts as a thermal pathway for cooling silicon modules and chips. This study utilized Ansys Workbench to investigate the thermal runaway management methods for a carbon fiber plate integrated with detector chipsets, which generate substantial amounts of heat. Two different approaches were analyzed: a sandwich carbon foam design and a U-shaped carbon foam design. Both foam designs were bonded with epoxy interfaces to the plates and utilized stainless steel cooling pipes to conduct heat away from the assembly. Additionally, the study examined the impact of varying the thickness of the epoxy interfaces between the foams and carbon plate. The results indicated that the thickness of the epoxy interfaces had a negligible effect on the maximum temperatures experienced by the plates. Furthermore, the sandwich foam design exhibited significantly superior performance, with an average temperature difference of nearly 15 degrees Celsius compared to the U-shaped foam design. These findings emphasize the effectiveness of the sandwich carbon foam approach in mitigating thermal runaway in carbon fiber plates integrated with heat-generating detector chipsets. The results from this parametric study will be used to inform the design and prototyping phase for the Inner Tracker Forward Pixel Detector Dees at Cornell University.
