ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

A compact diagnostic system for monitoring Hard X-Ray (HXR) in the KSTAR tokamak has been developed in this work. Its development aims for an extension of the counting rate limit, and a good time resolution in the hard X-ray diagnostic. The all-in-one compact HXR diagnostic system is based on NaI(Tl) scintillation detector, because this scintillator provides reliable identification of the X-ray energy spectra with high efficiency. And in addition, the electronic equipment such as preamplifier, main amplifier, high voltage power supply, and fast analog-to-digital converter (ADC) with a digital signal processor (DSP) system was built-in on boards as compact modules in the system. In particular, a fast ADC based on a DSP, and an amplifier with a shaping time of 100 ns was adopted to achieve 1 ms time resolution and a higher counting rate up to 1 MHz. This diagnostic system is intended to provide information on dynamic mechanisms of the high-energy electrons arising from when runaway electrons interact with plasma-facing components in the KSTAR tokamak.
