Salime Boucher (CEO) is a cofounder of RadiaBeam and has led the company through two decades of consistent growth and expanding capabilities. After graduating magna cum laude with a BS in Physics from UCLA, where he first fell in love with accelerators, he worked as an engineer with SureBeam, a manufacturer of industrial accelerator systems. Founding RadiaBeam, he successfully commercialized a diverse line of products, first developing instrumentation for the laboratory market, and more recently focusing on the industrial and medical markets. He has successfully negotiated license agreements with universities, most importantly for a portfolio of patents related to radiation therapy from UCLA. This formed the foundation for a spin-off, Celestial Oncology Inc., that is developing a new robotic radiotherapy system. Mr. Boucher is currently serving as interim CEO of Celestial, and has guided it from founding through Series A ($6 million in 2020). “There’s something about a beam of high energy particles that is just plain awesome,” he explains. “I especially like it when they can be used for something that makes people’s lives better.”

Alex Murokh (Chief Technical Officer) is an accelerator physicist and cofounder of RadiaBeam. Dr. Murokh leads the R&D division, with a focus on the R&D pipeline that drives the company’s longer term strategy on compact industrial light sources and advanced accelerators. Dr. Murokh received his Ph.D. from UCLA in 2002 for his work on VISA Free Electron Laser. At RadiaBeam, he also oversees collaborative research projects with universities and national laboratories and serves as the Principal Investigator of multiple R&D projects, including development of the compact Inverse Compton Scattering light sources, and high efficiency Free Electron Lasers.

Ronald Agustsson (Vice President of Engineering) has over 20 years of proven experience in multiple aspects of accelerator engineering encompassing accelerator system mechanical design, simulations, design for manufacturing, fabrication and validation. Over the course of his career, he has trained many engineers who have gone on to successful appointments within national laboratories worldwide or into accelerator-based industries. This diverse experience base is regularly employed in his management responsibilities leading a team of over a dozen engineers and specialized production personnel. Further, he has led the engineering efforts for hundreds of differing RF cavities, magnetic beam optics and vacuum systems delivered to national laboratories and industry worldwide.

Marcos Ruelas (VP of Sales) earned his BS in Physics with Honors from the University of California, Los Angeles in 2006. He describes himself as “a junior physicist turned part-time salesman.” Mr. Ruelas joined RadiaBeam as a Development Engineer in 2007 and was promoted to Director of the Instrumentation Group in 2010, where he managed the product development process for over $2 million in new diagnostics products sales in his first two years in that role. His success in these efforts led to his taking over the responsibility of all sales and marketing activities at RadiaBeam and he has directly managed or developed over $5 million in direct sales. But Ruelas hasn’t forgotten his scientific roots: he has continued to develop new products for both the research and commercial sectors as a team member, technical lead, and project manager. Notably, Mr. Ruelas is skilled in developing and managing national lab and industrial customer requirements and translating them to scientific and engineering goals with RadiaBeam’s technical and management teams.

Pedro Frigola (Senior Researcher and Cofounder) has more than 20 years of experience in particle accelerator technology. He currently leads our research program in additive manufacturing, also known as 3D printing. In 2007, he pioneered the use of additive manufacturing (AM) for the production of RF accelerating cavities, and is an inventor on several related patents. In 2020, he was one of the founding members of The Consortium on the Properties of Additively Manufactured Copper, a consortium that includes Fortune 500 companies, Universities, and small businesses working to develop and commercialize copper 3D printing technologies. In addition, he is responsible for ITAR compliance and maintaining and growing our intellectual property portfolio. He holds a private pilot’s license, and enjoys flying his airplane for business and pleasure.

Robert Berry (VP of Integration, Testing, and Support) is an engineer who focuses on system integration, design, and testing of accelerators. After the rest of the team develops new technology, someone verifies and test the products – Robert Berry and his team do that. He graduated with an M.S. in Engineering from the University of the Pacific with a focus on materials testing. Robert Berry’s background prior to RadiaBeam includes working at Lawrence Livermore National Laboratories, where he led mechanical operations at the linac accelerator facility and was pivotal in the design, setup and associated logistics for experiment setups on three accelerators housed within the lab. Robert also has developed interest in the advancement of SRF technology into industry focusing specifically on projects that remove the dependence of cryo-plants on such systems, using cryocoolers as alternatives. Mr. Berry has a deep appreciation for the nuances in system operation that are not always clearly captured in the upfront engineering and physics but need to be sussed out through operation.

Sergey Kutsaev, PhD. (RF Group Leader) has more than 15 years of experience in accelerator physics, including as an RF Engineer at ScanTech Sciences and at the Argonne National Laboratory. Dr. Kutsaev graduated Summa Cum Laude from the National Research Nuclear University (MEPhI) in Moscow, Russia, and holds a doctoral degree in accelerator physics. He then developed an accelerator system for Homeland Security applications. His work includes RF, THz optics, quantum computing, electronics, electromagnetic design, multiphysics and beam dynamics simulations and software technologies. Dr. Kutsaev published about 30 papers in peer-reviewed journals and is a reviewer for such journals as Physical Reviews, Journal of Instrumentation and Nuclear Instruments and Methods in Physics Research. At RadiaBeam, Dr. Kutsaev oversees companywide efforts on accelerator systems design. He has developed several commercial products, including medical accelerators, with the latest example of a thermionic RF gun, delivered and installed in APS injectors at ANL. Two more guns were purchased afterwards. For his achievements in accelerator physics, Dr. Kutsaev was elected as an IEEE Senior Member in 2020.
