Status of ion track technology—Prospects of single tracks

Radiation Measurements, 2005
Abstract A glimpse on the present status of ion track technology is provided: irradiation, etching and electro-replication of single and multiple ion tracks. The uses of an electrolytic cell for single and counted track studies are sketched. In connection with a data acquisition system such a device enables to determine in real-time: track and bulk ...

Formation of ion damage tracks

open access: yesPhysics Letters A, 1984
The formation of damage tracks in insulators from the passage of energetic (MeV/amu) ions indicates that the energy lost by an ion to electronic excitation is partially transferred to atomic motion. It is known that a track consists of localized regions of extended defects that are separated by lengths that exhibit only point defects.

Ion track doping

Radiation Effects and Defects in Solids, 1994
Abstract Longitudinal dopant distribution along ion tracks in soft (polymers [1–5]) and hard (diamond [6,7]) condensed carbonaceous matter have been studied by neutron depth profiling and cathodoluminesence. Both in-diffusion from the aqueous phase and energetic ion implantation were used in primary track doping.

Calculations of heavy-ion track structure

Radiation and Environmental Biophysics, 1994
A Monte Carlo model is presented to study details of the energy deposition inside tracks of heavy charged particles in water vapor. The input data for most of the calculations based on the binary encounter approximation are double-differential cross sections for electron emission after heavy-ion impact.

Microdosimetric measurements of heavy ion tracks

Advances in Space Research, 1992
The biological effectiveness of radiations depends on the spatial pattern of ionizations and excitations produced by the charged particle tracks involved. Ionizations produced by both the primary ion and by energetic delta rays may contribute to the production of biologically relevant damage and to the concentration of damage which may effect the ...

Ion-Track Etching

2004
Chemical etching of the ion-irradiated polymers is a process that transforms every latent track into a hole that, depending on conditions, may have a wide variety of shapes — long cylinders, short cones, hemispheres — and many others. All uses of ion-track etching are aimed either at getting information on the particles that created the tracks or at ...

Ion Tracking in Aqueous Sodium-Ion Batteries

ECS Meeting Abstracts, 2019
An energy economy based on renewable technologies will need energy storage capabilities on an enormous scale to combat power generation fluctuations. To provide the amount of energy storage that will be needed, low-cost batteries made with earth abundant elements will be a necessity for grid-scale storage.

Ion-Track Applications

2004
Just as low-energy ion irradiation of polymers has found a number of useful applications, also tracks of energetic heavy ions in polymers can be used in technology. In fact it took less than ten years after the detection of ion tracks (1958) for them to be applied (1967).
