NorthStar Medical Radioisotopes is an innovative radiopharmaceutical company utilizing an electron beam to produce radioisotopes for diagnosis and treatment of cancer. The team has designed an electronic signal producing sensor to characterize the transverse profile of their beam. The team also simulated energy deposition, heat transfer and electromagnetic fields to optimize the design’s operation in a high radiation and high vacuum environment. The sensor will help NorthStar adjust their beam parameters to ensure efficient power delivery and improved product quality.
