A model for MeV Cn track damage in YIG
نویسنده
چکیده
An experiment by groups at Ecole Polytechnique and Institute de Physique Nucl eaire (Orsay) used high resolution TEM to study the morphology of MeV C60 and C20 tracks in Y3Fe5O12 (YIG). Their data consist of measurements of latent track radii, total track lengths, and the length over which the radius remains constant. The one parameter in the model presented here is determined separately from the tracks of MeV/amu heavy ions in YIG; thus, the model uses no free parameters for ®tting the Cn data. The predicted track radii, the total track lengths, and the lengths with constant radius agree with the data to within 10%. The extension of this model to other details of track morphology will also be discussed. Ó 1998 Elsevier Science B.V. All rights reserved. PACS: 31.15.Qg; 34.50.-s; 34.50.Dy; 36.40.Sx

Evolution of the structure and morphology of latent tracks as a function of elec- tronic energy deposition
The creation of latent tracks in insulating materials exposed to energetic heavy ions has been studied in a large number of targets. In particular detailed results were obtained in yttrium iron garnet (YIG) Y3Fe5O12 irradiated in a broad range of electronic energy deposition (dE/dx)e both with monoatomic and cluster ions [1-4]. By means of Transmission Electron Microscopy (TEM) and channeling R...
متن کاملProton beam dosimetry by CR-39 track-etched detector
Background: High and intermediate energy protons are not able to form a track in a solid state nuclear track detector (SSNTD) directly. However, such tracks can be formed through secondary particles created during primary radiation nuclear reactions in a SSNTD. Materials and Methods: The protons with primary energies of 9.6 and 30 MeV available at the cyclotron accelerator with corresponding lo...

A new model is presented herein to calculate optimal value for ultra-cold neutron (UCN) production rate of a UCN source. The cold neutron (CN) converter is the main component of UCN source. In this paper, we study the UCN source which contains the D2O neutron moderator, the sD2 converter, 590 Mev proton beam, and the spallation target (a mixture of Pb, D2O and Zr). In order to determine the qua...
متن کاملPositron Annihilation Doppler Broadening Spectroscopy as Convenient Method to Detect Radiation Effect on CR-39 Track Detector
Positron Annihilation Doppler Broadening Spectroscopy (PADBS) is a characterization technique that is sensitive to damage of radiation in polymers. A damage zone or defect will be created due to the irradiation of Polyallyl diglycol carbonate (CR-39) with α-particles. It is convenient to study this defect caused by α-particle energies using both PADBS and track diameter measurements. An abrupt ...
متن کاملEffects of track characteristics on dynamic responses of train-bridge systems
High speed trains are an indispensable part of rapid transportation systems in many countries. As the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. Geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...
