About
C.J. Liaw is a leading engineer and applied physicist specializing in accelerator vacuum technology and surface engineering for high-energy particle colliders. Their major contributions center on developing robotic, in-situ plasma deposition systems to solve critical performance limitations in the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. Liaw designed and fabricated a novel "plasma magnetron mole"—a mobile robotic device capable of depositing thick, oxygen-free high-conductivity copper (OFHC) coatings inside long, narrow vacuum tubes. This innovation simultaneously addresses two major challenges: unacceptable resistive heating in stainless steel beam pipes and electron cloud formation that degrades machine performance. By creating low secondary electron yield (SEY) copper surfaces directly inside the accelerator's cold bore, Liaw's work provides a practical, in-situ solution without requiring tube disassembly. Though highly specialized, their key papers (each cited 3-4 times) represent foundational techniques for accelerator maintenance and performance enhancement. Liaw's achievements demonstrate how creative robotic surface engineering can extend the operational lifetime and beam quality of major research facilities like RHIC.
