The appearance of particle tracks in detectors
نویسندگان
چکیده
The phenomenon that a quantum particle propagating in detector, such as Wilson cloud chamber, leaves track close to classical trajectory is analyzed. We introduce an idealized quantum-mechanical model of charged periodically illuminated by pulses laser light resulting repeated indirect measurements the approximate position particle. For this we present mathematically rigorous analysis appearance tracks, assuming Hamiltonian quadratic position- and momentum operators, for freely moving or harmonic oscillator.

Optical appearance of alpha particle tracks in CR-39 SSNTD
A ray tracing method based on geometrical optics was used to study the tracks from alpha particles with different energies and with an incident angle of 50 . The transmission operation mode of the microscope is simulated. Considering the distribution of light intensities from the tracks, the mean and the 80% percentile gray levels from real experiments are proposed as quantitative variables to ...
متن کاملOptical appearance of alpha-particle tracks in CR-39 SSNTDs
The optical appearance of etched alpha-particle tracks in CR-39 SSNTDs under the transmission mode of the optical microscope were studied. The mean grey levels revealed using a digital camera installed on the microscope, together with the major and minor axes were systematically determined for tracks from alpha particles with different incident energies and angles. The grey level properties for...
متن کاملComputer program TRACK_VISION for simulating optical appearance of etched tracks in CR-39 nuclear track detectors
A computer program called TRACK_VISION for determining the optical appearances of tracks in nuclear track materials resulted from lightion irradiation and subsequent chemical etching was described. A previously published software, TRACK_TEST, was the starting point for the present software TRACK_VISION, which contained TRACK_TEST as its subset. The programming steps were outlined. Descriptions ...
متن کامل3-D imaging of particle tracks in solid state nuclear track detectors
It has been suggested that 3 to 5% of total lung cancer deaths in the UK may be associated with elevated radon concentration. Radon gas levels can be assessed using CR-39 plastic detectors which are often assessed by 2-D image analysis of surface images. 3-D analysis has the potential to provide information relating to the angle at which alpha particles impinge on the detector. In this study we...
متن کاملParticle detectors 1 28 . PARTICLE DETECTORS
Revised 2003 (see the various sections for authors). In this section we give various parameters for common detector components. The quoted numbers are usually based on typical devices, and should be regarded only as rough approximations for new designs. More detailed discussions of detectors and their underlying physics can be found in books by Ferbel [1], Grupen [2], Kleinknecht [3], Knoll [4]...
