In this interview, David Zierler, Oral Historian for AIP, interviews Thomas Appelquist, Eugene Higgins Professor of Physics at Yale University. Appelquist recounts his upbringing in rural Iowa and then Indiana, where he attended Catholic high school. He describes his undergraduate experience at Illinois Benedictine College and explains his attraction to attend a small school for college. Appelquist discusses his decision to attend Cornell for his PhD, and recalls that, relative to others in his cohort who went to larger schools, he had the most catching up to do in quantum mechanics. He explains the development of his thesis topic under the direction of Don Yennie, which focused on aspects of renormalization theory using the Feynman parametric approach. Appelquist contextualizes some of the broader questions in quantum field theory and quantum electrodynamics at this time, and he describes the opportunities that led him to SLAC for his postdoctoral research. He describes his interests there as focused on theories of the weak interactions, and he describes his initial faculty appointment at Harvard where he joined the particle theory group led by Shelly Glashow and Sidney Coleman. Appelquist discusses his close collaboration with Helen Quinn on how to renormalize Yang-Mills theories, and he explains his decision to take a tenured position at Yale in consideration of the culture at Harvard, where the prospects of tenure were minimal. He describes the revolutionary discoveries of asymptotic freedom, QCD, and the “November Revolution” at SLAC and Brookhaven at the time. Appelquist describes his research and administrative activities to advance the particle theory group at Yale, and his overall efforts to improve the department as chair and in particular building up the condensed matter theory group. He discusses his tenure as Dean of the Graduate School and his long-term involvement with the Aspen Center. At the end of the interview, Appelquist describes his current interests in lattice gauge theory and explains why he expects that physics will see double beta decay in the next generation of experiments.

Gilchriese describes his subsequent work on the solenoidal detector and his transfer to Berkeley Lab to succeed George Trilling and to join the ATLAS collaboration. He explains the migration of talent and ideas from the SSC to CERN and discusses the research overlap of ATLAS and CMS and how this accelerated the discovery of the Higgs. Gilchriese describes his next interest in getting into cosmology and searching for dark matter as a deep underground science endeavor, and he explains why advances in the field have been so difficult to achieve. At the end of the interview, Gilchriese describes his current work on CMB-S4, his advisory work helping LBNL navigate the pandemic, and he reflects on the key advances in hardware that have pushed experimental physics forward during his career.

Interview with Malcolm Roy Beasley, Sidney and Theodore Rosenberg Professor of Applied Physics, Emeritus, at Stanford. Beasley recounts his passion for basketball in high school and the opportunities that led to his undergraduate study at Cornell, where he describes his focus on engineering physics as just the right blend of fundamental and applied research. He describes his relationship with Watt Webb, who would become his graduate advisor, and the origins of BCS theory. Beasley discusses his work taking magnetization measurements on type-II superconductors and his thesis research on flux creep and resistance. He discusses his postdoctoral appointment working with Mike Tinkham at Harvard and the developments leading to reduced dimensional superconductivity. Beasley explains the technological implications in the fluctuations of the order parameter, and he describes the speed with which Harvard made him a faculty offer. He discusses the circumstances that led to him joining the faculty at Stanford, his immediate connection with Ted Geballe, and his work on A15 superconductors. Beasley explains the significance of the 1976 Applied Superconductivity Conference and the important work in the field coming out of the Soviet Union at the time. He conveys the excitement regarding amorphous silicon and how the KT transition in superconductors became feasible. Beasley describes his interest in thermal fluctuation limits and coupled oscillators, and he describes Aharon Kapitulnik’s arrival at Stanford and the origins of the “KGB” group. He describes the group’s work on alloyed-based model systems and his idea to study high-resistance SNS Josephson junctions. Beasley explains “Pasteur’s quadrant” and why the KGB group was so well-attuned to dealing with it, and he discusses the impact of computational theory on the field and specifically that of Josephson junctions on digital electronics. He surmises what quantum superconductivity might look like, and he describes his work as dean and as founding director of GLAM, and some of the inherent challenges in the “trifurcation” at Stanford between the Departments of Physics and Applied Physics and SLAC. Beasley discusses his leadership at APS and the issue of corporate reform, and he explains his role in the Schön commission and what it taught him about scientific integrity. At the end of the interview, Beasley reflects on some of the “forgotten heroes” in the long history of superconductivity, he attempts to articulate his love for physics, and he explains why the achievements of the KGB group represent more than the sum of its parts.

This interview is part of a series conducted during research for the book Tunnel Visions, a history of the Superconducting Super Collider project. It mainly addresses parts of Sir Christopher Llewellyn Smith’s career prior to his time as CERN Director-General, a position he held from 1994 to 1999, focusing on international perspectives surrounding the proposal and construction of large collider facilities. It covers his service as the scientific advisor to the 1984 Kendrew inquiry, which assessed UK membership in CERN, and to another inquiry, led by Anatole Abragam, which assessed CERN’s management. The interview extensively covers CERN’s preparations to build what became the Large Hadron Collider (LHC) in the tunnel where the Large Electron-Positron (LEP) collider was built, and how those preparations were influenced by the U.S. move to build the SSC and, later, by the SSC’s declining political fortunes and termination. Llewellyn Smith offers his perspectives on whether it would have been politically feasible in the 1980s to build a “world accelerator,” as well as on Japanese perceptions of U.S. plans for the SSC and the prospect that the U.S. could have secured contributions to the project from Japan. He also discusses early cost estimates for the LHC and their role in efforts to secure support for building it. The interview concludes with discussions of how CERN, the SSC, and the ITER fusion facility project were organized, and of the distinct roles of major facility directors and project managers.

In this interview, AIP Oral Historian Jon Phillips interviews Dr. Sean Brennan, emeritus physicist at the Stanford Synchrotron Radiation Laboratory.

He discusses his early work at SLAC with Jo Stohr on X-Ray absorption experiments, and his post-doc at Exxon. Brennan goes on to discuss the development of the facilities and research at SLAC over the course of his tenure there, as well as his work on the NASA Stardust project analyzing asteroid and comet samples. The interview concludes with a discussion of Brennan’s activities after retirement, including programming apps and serving as a ski patrol rescue worker.
