Alex Bien
Accel System Operator I, SLAC National Accelerator Laboratory
BioI am a 2022 graduate with a B.S. in physics from the University of Maryland at College Park, and I currently operate the world's longest and most powerful linear particle accelerator administrated by Stanford University under the direction of the US Department of Energy. Here I interface directly with the machinery, controls, and safety systems for three linear accelerator facilities: FACET-II where electron-pair beams are shot thru hot plasma to study novel wakefield acceleration techniques, LCLS where coherent x-rays of very high energy (and inversely low wavelength) probe deep into matter for imaging at atomic scales, and LCLS-II where commissioning is underway to produce a much more powerful megahertz rep rate superconducting beam that can leverage the same XFEL mechanism to (instead of just taking snapshots) also resolve the dynamics of chemical reactions in situ.

Olivier N. Bonin
Digital Media Specialist, SLAC National Accelerator Laboratory
BioBorn in the French Alps, I did a Master in Electrical and Micro-Electronic Engineering. I was an engineer in the Silicon Valley for 10 years developing semiconductor libraries of components for use on chips by many of the big names in the industry. After the last company I worked with was sold in parts, I left the industry to work on a full feature documentary about Burning Man. The film, Dust & Illusions, focused on a 30-year history that surprisingly nobody ever explored before. That lead me to develop video content for various companies, such as Whole Foods, Samsung, Stanford until I joined WildAid for a year producing videos to help stop the illegal wildlife trade (that potentially led to the covid-19 pandemic). Finally today I am the video and multimedia producer for SLAC National Accelerator Laboratory with the goal of bringing attention to the fundamental research in physics and biology that the Lab focuses on.

Cameron Bravo
Project Scientist, SLAC National Accelerator Laboratory
BioBorn in Kansas City, Missouri and attended high school in Peculiar (Ray-Pec). Undergraduate studies at the University of Nebraska - Lincoln, the Paul Scherrer Institute, and the Swiss Federal Institute of Technology (ETH Zurich). Studied ASIC design after helping characterize the PSI46 pixel chip used in the CMS detector. Graduate education at UCLA searching for Electroweak Sphalerons in proton-proton collisions with the CMS experiment while working on the muon system. Wrote BaryoGEN, a new Monte Carlo generator, to study all possible B+L violating fermion configurations potentially generated via Sphalerons and/or Instantons. Interests include front-end detector electronics, DAQ systems, gas detectors, Si detectors, non-perturbative physics (especially within the Standard Model), High-Multiplicity Electroweak Boson production, and exotic dark matter models. Currently working with the Heavy Photon Search (HPS) experiment on the Silicon Vertex Tracker (SVT) sub-system and searching dark sector models with an A' lighter than the dark matter threshold, SIMPs, and true muonium.

Martin Breidenbach
Professor of Particle Physics and Astrophysics, Emeritus
BioI have worked for more than 45 years in experimental particle physics, often in developing new kinds of electronics and instruments critical to the detectors that enable the physics experiments of interest. In 1965 through 1971, I was involved in the electron scattering program at SLAC. The deep inelastic experiments that discovered the scaling and point like structure in the nucleon, later interpreted as quarks, was my Ph.D. thesis. I then spent a year at CERN, mostly doing an experiment on minimum bias behavior of proton-proton scattering at the newly operating Intersecting Storage Rings. Despite intentions to stay longer at CERN, I was persuaded by Professor Richter to return to SLAC and join his SPEAR storage ring group. In the 1974 “November Revolution”, we discovered the and ’ particles, soon interpreted as bound states of charm-anti-charm quarks, which caused essentially complete acceptance of the quark model as real. Another critical discovery at SPEAR was the lepton, leading to the third family of the Standard Model.
Subsequently Professor Charles Baltay and I were co-spokesmen of the SLD, a comprehensive large detector for the SLAC Linear Collider (SLC), where we did Z physics, particularly polarization asymmetries possible because of the SLC polarized electron beam which led to a (correct) prediction of the Higgs mass, and precision b physics with a 300 MPixel CCD vertex detector.
I am now involved in the design of a detector for the International Linear Collider which may be built in Japan, which has led to substantial involvement in Si detector sensors and associated readout ASIC’s. I believe we have developed the first wafer scale sensors with on sensor traces leading to a relative small area “readout system on a chip” that delivers processed digital signals to a DAQ.
I also work on a search for neutrinoless double beta decay (02) in 136 Xe. The 02 experiment utilizes a liquid xenon TPC requiring ultra-low background materials, techniques, and locations, which was an education into rather different experimental techniques from collider detectors.
I am working on a new concept for an e+e- linear collider called C^3 for the Cool Copper Collider. The Cool Copper Collider (C3) is an advanced concept for a high energy e+e- linear collider. It is based on a new SLAC technology that dramatically improves efficiency and breakdown rate. C3 uses distributed power to each cavity from a common RF manifold and operates at cryogenic temperatures (LN2, ~80K). This makes it robust at high gradient: 120~MeV/m.
C3 is a promising option for a next-generation e+e- collider. It has the potential to reach energies of up to 1 TeV, which would allow it to study the properties of particles that are difficult to access with current experiments. C3 is also relatively affordable, which makes it a more viable option than some of the other proposed linear colliders.
Finally, these recent experiences have led to exploratory collaborative efforts in neuroscience, where we believe our SLAC expertise in sensors and electronics could be rather synergistic with Stanford efforts in tACs and in neural recording probes. -

BioPhil Bucksbaum holds the Marguerite Blake Wilbur Chair in Natural Science at Stanford University, with appointments in Physics, Applied Physics, and in Photon Science at SLAC. He conducts his research in the Stanford PULSE Institute (https://web.stanford.edu/~phbuck). He and his wife Roberta Morris live in Menlo Park, California with their cat. Their grown daughter lives in Toronto.
Bucksbaum was born and raised in Iowa, and graduated from Harvard in 1975. He attended U.C. Berkeley on a National Science Foundation Graduate Fellowship and received his Ph.D. in 1980 for atomic parity violation experiments under Professor Eugene Commins, with whom he also has co-authored a textbook, “Weak Interactions of Leptons and Quarks.” In 1981 he joined Bell Laboratories, where he pursued new applications of ultrafast coherent radiation from terahertz to vacuum ultraviolet, including time-resolved VUV ARPES, and strong-field laser-atom physics.
He joined the University of Michigan in 1990 and stayed for sixteen years, becoming Otto Laporte Collegiate Professor and then Peter Franken University Professor. He was founding Director of FOCUS, a National Science Foundation Physics Frontier Center, where he pioneered research using ultrafast lasers to control quantum systems. He also launched the first experiments in ultrafast x-ray science at the Advanced Photon Source at Argonne National Lab. In 2006 Bucksbaum moved to Stanford and SLAC, and organized the PULSE Institute to develop research utilizing the world’s first hard x-ray free-electron laser, LCLS. In addition to directing PULSE, he has previously served as Department Chair of Photon Science and Division Director for Chemical Science at SLAC. His current research is in laser interrogation of atoms and molecules to explore and image structure and dynamics on the femtosecond scale. He currently has more than 250 publications.
