Research

I started my career pursuing a PhD in accelerator physics at State University of New York at Stony Brook. My research topics were performance limiting beamdynamics mechanisms with the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory (BNL). During the next 35 years, my research has been on accelerator physics and engineering pertaining to frontier accelerator facilities including RHIC at BNL, the U.S. part of the Large Hadron Collider at CERN, the Spallation Neutron Source at Oak Ridge National Laboratory in collaboration with Lawrence Berkeley, Los Alamos, Thomas Jefferson, Brookhaven, and Argonne National Laboratories, the China Spallation Neutron Source project, the Compact Pulsed Hadron Source in China, and now FRIB. The accelerator profession is so uniquely rewarding in that a physical idea can be turned into reality through the execution of a construction project. Throughout its completion one experiences endless learning in physics, technology, teamwork, and creating friendships.

I serve as the FRIB Accelerator Systems Division Director responsible for the design, R&D, construction, commissioning, and operations of the accelerator complex. My team includes accelerator faculties and staff of subject-matter experts, many from major national laboratories and institutes worldwide. The accelerators at FRIB are among the most powerful and technically demanding hadron accelerators in the world. The design and development of the FRIB driver accelerator requires the most advanced knowledge in accelerator physics and engineering involving beam dynamics with electroncyclotron-resonance (ECR) ion sources, radio-frequency quadrupole (RFQ) linac, superconducting RF linac; space charge and beam halo; charge stripping mechanisms based on solid film, liquid-metal film, and gases; highpower targetry; mechanisms of beam loss, collimation, and collection; mechanisms of vibration, microphonics, and compensation; and mechanisms of gas dissorption, electron cloud, and mitigations; and rare-isotope beams.

My scientific research involves accelerator physics of highenergy colliders and high-intensity hadron accelerators; beam cooling and crystallization; development of spallation neutron sources; development of compact pulsed hadron sources; development of hadron therapy facilities; development of accelerator driven sub-critical reactor programs for thorium energy utilization and nuclear waste transmutation; and development of accelerators for rare-isotope beams. Our team covers accelerator research and engineering fields of superconducting material and technology; low-temperature cryogenics; permanent and electromagnetic magnets and power supplies; radio-frequency vacuum; beam diagnostics instrumentation and electronics; accelerator controls and machine protection; and beam collimation and shielding. Design, R&D, construction, commissioning, and upgrade of the FRIB accelerator complex involve fascinating and challenging works across multiple disciplines at Michigan State University and in collaboration with major accelerator institutes and laboratories in United States and throughout the world.
