Title of speech: Shared talk on FELs: A Historical Perspective (with Andrea Doria)
George Neil was the Senior Team Lead for the LCLS-II Project at the Thomas Jefferson National Accelerator Facility (Jefferson Lab), a Department of Energy particle accelerator facility run for nuclear physics research. The LCLS-II Project was a new DOE Basic Energy Sciences program centered at Stanford National Accelerator Facility involving the construction of an X-ray Free Electron Laser powered by a 4 GeV continuous wave superconducting accelerator. Jefferson Lab’s responsibility included constructing roughly half of the accelerator and the cryogenics plant.
Neil’s past responsibilities as Principal Scientist of the lab included serving as Laboratory Associate Director and Manager of the Free Electron Laser Division while developing the Free-Electron Laser (FEL) systems that converted electron-beam energy into light and applied that light for materials processing. These systems set world records for Free Electron Laser average power in 1996 and held the record since that time producing up to 14 kW of continuous average power. During the construction of the CEBAF accelerator, he managed the development and maintenance of roughly 350 radio-frequency sources at 1500 MHz for the linear accelerator and the development and operation of what was at that time, the world’s largest 2K helium refrigeration plant.

Fritz Keilmann
Affiliation: Fakultät für Physik & Center for NanoScience (CeNS) Ludwig-Maximilians-Universität München, Germany
Title of speech: The Roots of THz Near-Field Microscopy
Fritz Keilmann began his career in science at the age of 14, when he became the local meteorologist for his Alpine community southwest of Munich, Germany. From 1967 to 1971, he worked at Garching as it transitioned to the Max Planck Institute for Plasma Physics. He did a post-doctoral appointment at MIT between 1972–1973 and then took up a post at the Max Planck Institute for Solid-State Research (Festkörperforschung) in Stuttgart. Except for a short Visiting Scientist appointment at University of California, Santa Barbara, USA, in 1987, he remained at Stuttgart through 1995, earning a permanent position at the Max Planck Gesellschaft in 1977. From 1995–2007, he did research at the Max Planck Institute for Biochemistry in Martinsried where he worked until his formal retirement from Max Planck. He started two companies, Lasnix in 1984 and Neaspecs in 2007, upon leaving Max Planck. Keilmann returned to Max Planck as a Distinguished Scientist in 2008, forming a new group at the Institute for Quantum Optics in Garching focused on mid IR broadband laser sources. His most recent move was to the historic Ludwig Maximilians University in Munich, where he has set up a laboratory in the Department of Soft Matter Physics to work on nanoscopy of biomaterials.
Dr. Keilmann has explored many areas and applications in infrared physics and spectroscopy. His interests were always focused in the infrared, but he was often drawn into biochemistry and biophysics, where he initially worked on molecular spectroscopy of biomolecules and later on microwave effects on cell systems. Today, he is focusing on understanding the basic structure, evolution and impact of mineralization in osteoporosis. Dr. Keilmann also worked extensively on high power laser sources, especially optically pumped IR lasers and their applications for plasma science and nonlinear solid-state spectroscopy. He is credited with inventing the scattering-type scanning near-field optical microscope, the nano-FTIR, and the dual-frequency-comb spectrometer.
He has published more than 150 peer reviewed papers, holds 14 patents, and has contributed to five textbooks. He is an internationally recognized speaker and has given more than a hundred invited presentations at workshops, conferences and seminars. He is a recipient of the 2009 Kenneth J Button Prize.
