Fission Fragments Track- Etched Pores in Borate Glass
نویسندگان
چکیده
A study has been made to investigate the detection sensitivity of Borate Glass for the heavily ionizing fission fragment tracks. The latent damage tracks produced by fission fragments in Borate Glass, with and without Aluminium Oxide as an additive, have been studied under a high resolution scanning electron microscope. Tracks have been found and studied only in the Borate Glass samples with no added Aluminium Oxide. Analysis has been carried out according to an etching model and in comparison to Cu ion tracks in CR-39.

Ion-Track Annealing Kinetics in Apatite
Fission tracks in minerals, such as apatite and zircon, generated by energetic nuclear fragments that result from spontaneous fission of U, are used for determining the age and thermal history of Earth’s crust. Taken together with other techniques, the data infer rates of tectonic uplift and landscape evolution [1]. At elevated temperatures, these tracks shrink in size and fragment into section...
متن کاملPhoto-Spectro-Metric Study of CR-39 Detectors Irradiated with Heavy Ions
The fission fragments and heavy ions tracks in CR-39 detectors registered by Cf-252 radioactive source have been observed by using photo-spectrometric techniques. CR39 detectors were exposed at 5 cm distance from radioactive source for registering nuclear tracks created by nuclear particles emitted from Cf-252 radioactive source. Cr-39 detectors were etched in 6N NaOH solution at 70 C for 400 m...
متن کاملNanopores with controlled profiles in track-etched membranes
The production of the track-etched membranes is well known in membrane science. Latent ion tracks are the result of the passage of swift ions through solid matter, they can be etched selectively in many materials. As a result, conical, cylindrical or other shape channels can be obtained. The increasing interest in polymer track-etched membranes with nano-channels is connected with the developme...
متن کاملImproved fission-track length measurements using ion irradiation
Apatite [Ca5(PO4)3(F,Cl)] is a common mineral in rocks that contains ~10 ppm U. U disintegrates by spontaneous fission and the fission fragments produce linear damage trails of ~20 μm length and 5-10 nm width. The lattice damage along such a fission track is repaired at elevated temperatures, leading to a gradual decrease of its etchable length. Since fresh tracks are formed as existing tracks ...
متن کاملCharacterization of track-etched membranes by small-angle x-ray scattering
Track-etched membranes are polymer foils irradiated with swift heavy ions and subsequently wet-etched to create pores by dissolving defects formed along the ion trajectories. Under suitable conditions, the resulting pores are of cylindrical shape and uniform in size. Such membranes are commonly used for filtration or as templates for nanowires, grown inside the pores, e.g., by electrochemical d...
