Abstract

A Salt Lake City (Utah) based Component Division of Varian Medical was spun-off in 2016 and has become an independent public company Varex Imaging Corporation (VREX, NASDAQ) in January 2017. Since the spin-off, we have designed, produced, and tested several Accelerator Beam Centerline (ABC) prototypes to meet or exceed the parameters of the Varian-built predecessors, and some ABC models have been released to production. The primary objective set by the Sunny Sanyal, CEO of Varex, was to develop Varex’s own Linac technology that would be a step ahead of current technologies and form the basis of future high energy applications roadmap for Varex; namely, build 3 MeV, 6 MeV, and 9 MeV basic models, in the first place, and eventually, develop advanced products and make Varex an undisputed leader in the field. The fundamental objective has been accomplished and our pilot production line produced 20, 65, and finally, more than twice that much, way exceeding 100, in consecutive fiscal years of 2022, 2023, and 2024, correspondingly. Our LINAC high-power testing was performed only at our Las Vegas facility, but recently, a test cell at our production facility in Salt Lake City was built in May 2024. A LINAC utilizing 6 MeV ABC represents bulk of Varex units shipped in 2024, the LINAC has been fully tested and released to production in a Diode Electron Gun (DEG) and a Triode Electron Gun (TEG) based versions. A LINAC system Mi6SSM-T is designed based on Mi6SSM product, utilizing TEG and TEG High Voltage (HV) Driver (TEGD). Over 100 new LINAC Systems based on our new ABCs have been shipped to Varex customers. The TEGD is composed in a 19” Mi6SSM rack-mounted assembly, but it can be installed in the LINAC X-ray or Electron Beam Head for designs based on the “legacy” LINATRON models. In addition, we are developing new linac models, and some are groundbreaking designs. We have designed and tested MicroBeam LINATRON^TM with ABC-6-S-M-X-T-SUBMM, delivering less than 500 m spot size (estimated 350+150 m) and only 12.5% maximum dose rate reduction (700 R/min@1m), compared to a standard ABC-6-S-M-X-T (800 R/min@1m). We have bench-tested a new upgraded M9V accelerator, operating at 9 MeV and delivering substantially higher dose rate (maximum over 5000 R/min@1m) of its predecessor M9 (rated at 3000 R/min@1m). Our new K15V, or V15 (under development) will operate at our common frequency 2998 MHz, and it utilizes a patented hybrid standing and traveling wave design. The first 9 MeV section can be a separate machine (V9), that will deliver very high dose rates, while drastically reducing the produced neutron yields, compared to K-15.

A LINAC system Mi6SSM-T is designed based on Mi6SSM product, utilizing TEG and TEG High Voltage (HV) Driver (TEGD). Over 100 new LINAC Systems based on our new ABCs have been shipped to Varex customers. The TEGD is composed in a 19” Mi6SSM rack-mounted assembly, but it can be installed in the LINAC X-ray or Electron Beam Head for designs based on the “legacy” LINATRON models. In addition, we are developing new linac models, and some are groundbreaking designs. We have designed and tested MicroBeam LINATRONTM with ABC-6-S-M-X-T-SUBMM, delivering less than 500 m spot size (estimated 350+150 m) and only 12.5% maximum dose rate reduction (700 R/min@1m), compared to a standard ABC-6-S-M-X-T (800 R/min@1m). We have bench-tested a new upgraded M9V accelerator, operating at 9 MeV and delivering substantially higher dose rate (maximum over 5000 R/min@1m) of its predecessor M9 (rated at 3000 R/min@1m). Our new K15V, or V15 (under development) will operate at our common frequency 2998 MHz, and it utilizes a patented hybrid standing and traveling wave design. The first 9 MeV section can be a separate machine (V9), that will deliver very high dose rates, while drastically reducing the produced neutron yields, compared to K-15.},

AB  - A Salt Lake City (Utah) based Component Division of Varian Medical was spun-off in 2016 and has become an independent public company Varex Imaging Corporation (VREX, NASDAQ) in January 2017. Since the spin-off, we have designed, produced, and tested several Accelerator Beam Centerline (ABC) prototypes to meet or exceed the parameters of the Varian-built predecessors, and some ABC models have been released to production. The primary objective set by the Sunny Sanyal, CEO of Varex, was to develop Varex’s own Linac technology that would be a step ahead of current technologies and form the basis of future high energy applications roadmap for Varex; namely, build 3 MeV, 6 MeV, and 9 MeV basic models, in the first place, and eventually, develop advanced products and make Varex an undisputed leader in the field. The fundamental objective has been accomplished and our pilot production line produced 20, 65, and finally, more than twice that much, way exceeding 100, in consecutive fiscal years of 2022, 2023, and 2024, correspondingly. Our LINAC high-power testing was performed only at our Las Vegas facility, but recently, a test cell at our production facility in Salt Lake City was built in May 2024. A LINAC utilizing 6 MeV ABC represents bulk of Varex units shipped in 2024, the LINAC has been fully tested and released to production in a Diode Electron Gun (DEG) and a Triode Electron Gun (TEG) based versions. A LINAC system Mi6SSM-T is designed based on Mi6SSM product, utilizing TEG and TEG High Voltage (HV) Driver (TEGD). Over 100 new LINAC Systems based on our new ABCs have been shipped to Varex customers. The TEGD is composed in a 19” Mi6SSM rack-mounted assembly, but it can be installed in the LINAC X-ray or Electron Beam Head for designs based on the “legacy” LINATRON models.
