This research and development initiative focuses on the mechanical aspects of target wheel systems, specifically the magnetic immersion effects as demonstrated in the Daresbury experiment. Key areas of study include pass-through sealing methods to address vacuum and water leaks, thermal loading impacts, and radiation hardness material behavior. The project explores repeated loading effects, including creep and fatigue, with an emphasis on stress-thermal interactions. It also delves into alternative materials, design validation for cooling channels, and advanced instrumentation for control systems, aiming to enhance target wheel performance and lifespan.
