On the optical contrast of particle tracks in nuclear track detectors
Nuclear Instruments and Methods, 1976Abstract A study was made of the optical contrast of alpha-particle tracks normally incident on cellulose nitrate at all the phases of their development. Measurements of the optical contrast of the spots were performed using a microdensitometer. It was found that the maximum contrast corresponds to the point at which the particle reaches the end of ...

Particle identification by dielectric track detectors
Radiation Effects, 1970Abstract Chemical reactivity along the trajectory of a charged particle in a dielectric solid depends on the density of radiation-damaged species. In inorganic crystals such as are found in meteorites, cosmic rays can be identified by etching for a long time and measuring the entire etchable ranges of the slowing particles, which are related to their ...

Hollow particle tracks in AgCI-detectors
Radiation Measurements, 1995Abstract In selected Cd-doped monocristalline silverchloride detectors we observe developed tracks from particles at LET values > 300 keV/μm AgCl and charge state values > 9, without a visible central region: the “hollow track”. The microdensitometric lateral profile shows a density decrease near the track axis, up to a radial extension of some ...

Optimization of detector positioning in the radioactive particle tracking technique
Applied Radiation and Isotopes, 2014The radioactive particle tracking (RPT) technique is a non-intrusive experimental velocimetry and tomography technique extensively applied to the study of hydrodynamics in a great variety of systems. In this technique, arrays of scintillation detector are used to track the motion of a single radioactive tracer particle emitting isotropic γ-rays.

Object tracking by deep object detectors and particle filtering
2018 26th Signal Processing and Communications Applications Conference (SIU), 2018Developing object tracking techniques robust to blur, scale changes, occlusion and illumination changes is a challenging problem for several applications. Recently many algorithms using deep learning for visual object tracking are proposed. These algorithms mostly perform object detection without using the temporal information for video object tracking.

Nuclear track detector characterization for alpha-particle spectroscopy
Radiation Measurements, 2013Abstract Solid State Nuclear Track Detectors (SSNTDs), CR-39™ type, are usually adopted in many applications in which it could be necessary to select tracks according to the incident alpha-particle energy; so several authors have argued that track parameters such as the major/minor axis being the most often reported, can be used to determine the ...

Development of a Triple GEM Detector for Particle Tracking
IEEE Nuclear Science Symposium Conference Record, 2005, 2006Results of studies for the feasibility of a triple GEM detector as the inner tracking system of the LHCb inner tracker are presented. This is the first time full scale prototypes of triple GEM detectors have been built. The timing resolution of the triple GEM detector was investigated using a special amplifier. In several beam tests the performances in

Mechanism of particle track etching in polymeric nuclear track detectors
Nuclear Instruments and Methods in Physics Research, 1982Abstract A mechanism of particle track etching in polymers is proposed, which is based on the assumption that a free reaction volume is required for enhanced chemical degradation in a particle track. The free reaction volume ν ∗ is supposed to be formed from the holes with a free volume νf, which were produced in the latent track by ...

A new method of imaging particle tracks in solid state nuclear track detectors
Journal of Microscopy, 2009SummarySolid state nuclear track detectors are used to determine the concentration of α particles in the environment. The standard method for assessing exposed detectors involves 2D image analysis. However 3D imaging has the potential to provide additional information relating to angle as well as to differentiate clustered hit sequences and possibly ...
