Rotating Beam Dump (2024-2026)
High-power beam interception motivates the study of water-cooled rotating designs. Thermal-structural analysis evaluates heat deposition and stress, alongside electromagnetic effects from nearby dipole magnets.
Post-Target Shielding (2025-2026)
As FRIB ramps up power, the post-target shielding (PTS) requires optimized cooling channel design and structural stress analysis due to thermal stresses. The heat distribution calculated from PHITS Monte Carlo simulations was coupled with COMSOL to minimize stress and develop a practical design for field implementation.
Plasma Chamber (2025-2026)
Plasma-chamber temperature predictions compared between ANSYS and COMSOL.
Thermal and structural analyses in ANSYS and COMSOL were compared to assess RF-power thermal limits. This is a cross-code comparison, distinct from experimental validation. Transient analysis also evaluated the temperature and assembly time needed for interference fitting of the cooling-channel components.
Low-Power Charge Selector (2025-2026)
Simulated and measured temperatures used to estimate beam energy deposition.
Performed transient and stationary thermal simulations of the Low-Power Charge Selector (LPCS) to determine power limits based on thermal stress. By comparing simulation results with experimental measurements, the beam deposit on the drift tube was predicted.
Target System (2024-2025)
Performed system-level thermal analysis for the graphite-based rotating target, including radiation effects on the target door cooling and flow rate requirements. Simulations and experiments were conducted to evaluate the thermal conductance and operational limits of the bearing system.
