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.

The fission chamber plays a key role in International Thermonuclear Experimental Reactor (ITER) neutron flux measurement. However, the matched preamplifier cannot tolerate the strong radiation of ITER. This can be solved by using a cable to transmit the signal from the detector to the preamplifier. The object of this project is to develop charge preamplifiers that admit a long cable as input. The input stage and gain stage of the charge preamplifier in previous work have been improved to reduce the rise time and noise degradation caused by the capacitance of the long cable. The experimental results confirm that the preamplifier can admit the fission chamber detector and a 20-m cable.
