110277 - MAN-PORTABLE LINAC-BASED X-RAY SOURCES FOR NDT AND NUCLEAR SECURITY APPLICATIONS 

Electron accelerators operating at energies of 1-10 MeV and power levels of 1-30 kW are used for many industrial applications, including medical device sterilization, non-destructive testing (NDT), cargo inspection, and radiotherapy. However, many of these applications, especially novel ones, require that size, weight, and costs of the accelerators are significantly reduced to be considered as a suitable source of radiation. Some examples of such applications include field radiography, mobile cargo inspection, radioactive source replacement and industrial irradiation such as wastewater treatment. The dramatic level of miniaturization and cost-reduction is achieved thanks to the implementation of such innovative technologies as high-frequency magnetrons, split accelerating structure fabrication technology, and solid-state Marx modulators.

RadiaBeam is an accelerator technology R&D company that designs and manufactures linear accelerators and systems for such applications, as well as electron beam sources, instrumentation, and diagnostic systems for research laboratories. Simultaneous engagement with the research and industrial markets often guides RadiaBeam towards developing custom and semi-custom irradiation systems, specifically tailored to address the needs of customers either in niche markets or engaged in the experimental application studies, where off the shelf accelerator solutions are not readily available. In this presentation we will review some examples of such custom systems developed in recent years, including self-contained irradiator systems, custom linacs for medical applications, energy modulated high current accelerators for NDT, and other systems, where our case studies of the accelerator system optimization for specific applications could be of interest to the broader community.

Presenting Author Biography: Sergey V Kutsaev, Ph.D. is a Senior Scientist and RF Group Leader at RadiaBeam. Dr. Kutsaev’s two-decades experience in accelerator physics includes work as an RF Engineer at ScanTech Sciences, LLC, where he developed an accelerator system for Homeland Security applications. Next, he worked in the Linac Development Group at the Physics Division of Argonne National Laboratory on a wide spectrum of problems including heavy-ion linacs and superconducting RF cavities. At RadiaBeam, Dr. Kutsaev leads multiple projects and oversees companywide efforts on accelerator systems design and electromagnetic simulations. Dr. Kutsaev is a project leader or PI of many DOE SBIR grants that include RF, accelerator, magnet, THz optics, quantum computing, electronics, and software technologies. Dr. Kutsaev has developed several commercial products, including medical accelerators, sold by RadiaBeam, and the thermionic RF gun, installed in the APS injector at ANL. For this development, RadiaBeam received the Small Business of the Year award from the U.S. Department of Energy in 2022. For his achievements in accelerator physics, Dr. Kutsaev was elected as an IEEE Senior Member in 2020. From 2021, Dr. Kutsaev serves as an Expert for the International Atomic Energy Agency (IAEA) in questions of radioactive sources development.
Dr. Kutsaev has strong experience in multiple aspects of accelerator development such as electromagnetic design, RF engineering, multiphysics, and beam dynamics simulations. His experience in Quantum Information Systems includes the design and cryogenic testing of superconducting qubit cavities. Dr. Kutsaev published more than 50 papers in peer-reviewed journals, including invited and topical reviews, and more than 70 conference papers, and had multiple invited and plenary talks at International Conferences and Workshops. His papers were named as “Featured” and” Editor’s Suggestion” in Phys. Rev. Applied and Rev. Sci. Instrum. journals. Dr. Kutsaev has served as Guest Editor in Applied Sciences journal (IF~2.8), and as a reviewer for such journals as PRL, NIMA, JINST, RPC, IEEE TNS, and many others, as well as Session Chairmen at several conferences, including CAARI’22.
Academically, Dr. Kutsaev graduated Summa Cum Laude with the highest honors from Moscow Engineering-Physics Institute (MEPhI) under the supervision of prof. N.P. Sobenin and holds a doctoral degree in accelerator physics, earned through extensive work on design, fabrication, and testing of a dual energy electron linac for a cargo inspection system.
