High‑voltage power supplies are vital in nuclear instruments, providing the stable energy needed for detectors, accelerators, and isotope production systems. They are used in applications such as radiation monitoring, particle accelerators, nuclear reactors, and portable nuclear instruments, where precise voltage control ensures accurate measurements and safe operation. Reliable high‑voltage performance is crucial because even small fluctuations can compromise data integrity or device safety, making these supplies the backbone of modern nuclear science and radiation technology
