Abstract

<p>Nuclear track emulsion is a unique presence as a high spatial resolution and a three dimension detector in the field of fundamental physics. And the emulsion that Nobel Prize scholars Powell of the United Kingdom was introduced, has entered a new phase researchers to their own development. In this paper, the author organizes with respect to the prior knowledge of the fine grain emulsion and then discusses the emulsion design to discriminate the track of interest more precisely. First, the author presents a mechanism of photographic sensitivity to ionizing radiations, then introduces the latest high resolution emulsion and at the end discusses technologies of recombination prevention, of high-intensity reciprocity low failure and of track discrimination being an important in nuclear emulsion.</p>
