A new method for internal calibration of nuclear track detectors

Inter-comparison of geometrical track parameters and depth dependent track etch rates measured for Li-7 ions in two types of CR-39

“…The group from the Kobe University of Mercantile Marine (KUMM) has worked from a slightly different point of view, based on the measurements of both the track radius and the thickness of layer removed without the assumption of the constant track etch rate (Oda et al, 1992(Oda et al, , 1993. For the latter, we discovered that under certain conditions of incident energy and angle, the response near the Bragg peak doesn't reflect on the pit radius growth curves in principle, «missing track effect» (Yamauchi et al, 1995a(Yamauchi et al, , 1995b.…”

Observation of the inhomogeneous spatial distribution of MeV ions accelerated by the hydrodynamic ambipolar expansion of clusters

“…Each CR-39 detector was covered by a 6 m Al filter to protect it from damage induced by the transmitted portion of the main laser pulses and to block low energy particles below 0.6 MeV/n.

Potential Application of Nanoporous Materials in Biomedical Field

“…For the purpose of observation of rectification current voltage curves are used. [44,45] Ion current rectification is behavior seen in many nanoporous system. A biological nanopore as well as artificial nanopores shows rectifying behavior.…”
