Fusion Energy Science at UW Madison HSX stellarator Pegasus - III Large Facility Collaborations Fusion Neutronics Wi. PPL Theory & Computation

On-campus innovation and excellence paired with a strong large-facility collaboration program is the basis for success • Now: leading university fusion research and education program • A synergistically integrated program for research and education: advanced classes; on-campus research; off-campus large facility collaboration • Local experiments have unique international niches and are undergoing substantial upgrades • • Pegasus-III: non-solenoidal startup in spherical tokamak HSX-U: quasi-symmetry in stellarator geometry Wi. PPL: Frontier Plasma Science DOE user facility • Off-campus collaborations link local activities to the high performance domain • Collaborations at W 7 -X, DIII-D, NSTX-U, KSTAR, EAST, ASDEX-Upgrade • Fusion technology and plasma theory/computation are foundational for the scientific and technical depth in the program Future: new and exciting ideas are evolving from present program • Magnetic confinement: a new stellarator concept to demonstrate transport by design • Fusion technology: new neutron sources for material development; approached as public-private partnership with local company SHINE and Commonwealth Fusion

This is a successful model to produce top-notch science results and emit the largest amount of fusion and plasma graduates into the field • To date, more than 450 fusion and plasma graduates were emitted into the field – many of whom have become leaders at their institutions and in the community Whereabouts of UW Madison Fusion graduates

What is the role of fusion going to be in Physics going forward? • • Role of fusion research in Physics is strongly diminished since MST funding was lost and the US RFP program was cancelled Collaboration on facilities elsewhere is becoming a more common (Iter, DIII-D) Fusion technology Demographics
