Recent applications of nuclear track emulsion

Abstract

Application of the nuclear track emulsion technique (NTE) in radioactivity and nuclear fission studies is discussed. It is suggested to use a HSP-1000 automated microscope for searching for a collinear cluster tri-partition of heavy nuclei implanted in NTE. Calibrations of α-particles and ion ranges in a novel NTE are carried out. Surface exposures of NTE samples to a Cf-252 source started. Planar events containing fragments and long-range α-particles as well as fragment triples only are studied. NTE samples are calibrated by ions Kr and Xe of energy of 1.2 and 3 A MeV. Use of the image recognition program "ImageJ" for obtaining characteristics of individual events and for events from the large scan area is presented. *

“…Vertex and track reconstruction play a crucial role in various particle physics experiments, including those focused on neutrinos, dark matter, and other phenomena. A wide range of technologies are used for this purpose, such as emulsion film [1][2][3], cloud chamber [4], bubble chamber [5], spark chamber [6], multi-wire proportional chamber [7], TPC [8], Si strip [9], Si pixel [10], and others. In photon-based detection, commonly used techniques for timing, intensity, and rough spatial reconstruction include PMT or SiPM.…”
