“…The bulk etch rate (V B ) is relatively easy to measure by direct and indirect methods, but information on the track etch rate (V T ) is relatively scarce and very scattered. Since DHM allows the 3D visualizing of etched tracks with good accuracy, track etch rates can be determined by the time dependent track length method [33,34] or by the 3D-track wall method [35]. For the last case, track wall coordinates should be extracted from reproduced 3D track images by means of image analysis and computer calculations.…”

An alternative method to visualize and analyze etched tracks in LR-115 detectors was developed. The method is based on digital holographic microscopy which provides three-dimensional track images. Virtual volumes of simulated tracks were generated considering the refractive index and thickness of etched detectors, and the 3D track profiles produced by the TRACK_TEST program. The developed technique can faithfully reproduce the 3D shape of simulated tracks and their geometric parameters. It was also possible to visualize the 3D shape of experimental tracks. The residual thickness of LR-115 detectors can be determined from tracks that completely perforated the active layer.

Recent developments in ultrasonic material testing have increased the need to evaluate the current status of the different applications of piezoelectric elements (PEs). This research have reviewed state-of-the-art emerging new technology and the role of PEs in tests for a number of mechanical properties, such as creep, fracture toughness, hardness, and impact toughness, among others. In this field, importance is given to the following variables, namely, (a) values of the natural frequency to PEs, (b) type and dimensions of specimens, and (c) purpose of the tests. All these variables are listed in three tables to illustrate the nature of their differences in these kinds of tests. Furthermore, recent achievements in this field are emphasized in addition to the many important studies that highlight the role of PEs.

High resolution imaging of radiation is required for such radioisotope distribution measurements as alpha particle detection in nuclear facilities or high energy physics experiments. For this purpose, we developed an ultrahigh resolution radiation imaging system using an optical fiber structure scintillator plate. We used a ~1-μm diameter fiber structured GdAlO3:Ce (GAP) /α-Al2O3 scintillator plate to reduce the light spread. The fiber structured scintillator plate was optically coupled to a tapered optical fiber plate to magnify the image and combined with a lens-based high sensitivity CCD camera. We observed the images of alpha particles with a spatial resolution of ~25 μm. For the beta particles, the images had various shapes, and the trajectories of the electrons were clearly observed in the images. For the gamma photons, the images also had various shapes, and the trajectories of the secondary electrons were observed in some of the images. These results show that combining an optical fiber structure scintillator plate with a tapered optical fiber plate and a high sensitivity CCD camera achieved ultrahigh resolution and is a promising method to observe the images of the interactions of radiation in a scintillator.
