Detector Cooling System Thermal Studies

Overview

The timing detector's electronics rely on a high-pressure, two-phase evaporative CO2 cooling system to stay within safe operating temperatures. I'm responsible for the thermal studies behind that system — from early R&D prototyping through to test setups that validate performance under the full range of detector operational scenarios.

My Role

  • Responsible for thermal studies of the detector's evaporative CO2-based cooling system.
  • Designed, assembled, and commissioned test setups to study the thermal performance of the high-pressure two-phase cooling system and detector electronics.
  • Coordinated and executed thermal tests under all detector operational scenarios, running optimization studies to increase the heat-transfer performance of the cooling system.
  • Carried out Finite Element Analysis (FEA) of complex detector cooling lines in accordance with EN 13445 and EN 13480.
  • Supervised students working on static-structural and thermal simulations in ANSYS.
  • Started on this topic as a Technical Student, contributing to early R&D prototyping of the cooling system and control system development for data acquisition.
