Simulation of Particle Tracks in Emulsion
Micrographs of energetic particles in nuclear emulsion are simulated by computing the spatial distribution of developed grains with the δ-ray theory of track structure, and representing the developed grains by points of light on an IBM 2250 visual display unit. The simulated tracks display many of the features of actual track structure and serve as a visual comparison between experiment and the...
متن کاملAutomatic microscopes for nuclear emulsion readout in high-energy and particle physics
Nuclear emulsions feature unequalled spatial precision and resolution (better than 1 micrometer) among the detectors used for high-energy and particle physics. They can be used to perform topological study of interaction and decays of subnuclear particles, but the traditional workflow is heavily manpower-dependent. The quick development of electronic devices in the ‘70s and ‘80s made them progr...
متن کاملAcoustic particle velocity horns.
The paper considers receiving acoustic horns designed for particle velocity amplification and suitable for use in vector sensing applications. Unlike conventional horns, designed for acoustic pressure amplification, acoustic velocity horns (AVHs) deliver significant velocity amplification even when the overall size of the horn is much less than an acoustic wavelength. An AVH requires an open-en...
متن کاملParticle production in very-high-energy cosmic-ray emulsion chamber events: Usual and unusual events.
We show that a simple scaling model of very forward particle production, consistent with accelerator and air shower data, can describe all features of the very high-energy interactions recorded with emulsion chambers. This is somewhat surprising after numerous claims that the same data implied large scaling violations or new dynamics. Interestingly, we cannot describe some of the Centauro event...
متن کاملStudying Peak Particle Velocity Due to Blast in Development Tunnels’ Face in Coal Stoping
The impact of blast-driven shocks on the safety and stability of the underground coal mines has been well established. The seismic imperfections resulting from blasting depend on the total explosive energy released during blasting and the closeness of the development tunnel face to the stope face. Also, the quality of the rock mass wherein the whole stope face is located might pose considerable...
