Detection of Energetic Heavy Ions
The delta-ray theory of track structure, applied earlier to such 1-or-more hit detection systems as the inactivation of dry enzymes and viruses, the NaI(Tl) scintillation counter, and nuclear emulsion, is extended to the silver activated phosphate glass dosimeter, the LiF thermoluminescent dosimeter, the creation of free radicals in solid biological substances, solid and liquid organic scintill...
متن کاملInactivation of Dry Enzymes and Viruses by Energetic Heavy Ions
A newly developed corrected formula for the radial distribution of dose (RDD) has been used to calculate cross sections for the inactivation of dry enzymes and viruses by heavy ions ranging from 2He to 40 18Ar of energies ca. 10 MeV/a.m.u., spanning a range of LET of ca. 5–2,000 Me V cm2 g–1. In comparison with earlier “point-target” calculations of Butts and Katz where a linear range-energy re...
متن کاملTurbulent transport of energetic ions
Anomalous transport of heat and particles is known to be a key issue for fusion devices. In the present paper the anomalous transport of fast ions is investigated. High transit frequencies of the fast ions lead to the assumption that there is only very weak interaction with the low-frequency turbulence. However, our results indicate a significant fast ion particle transport due to the turbulenc...
متن کاملA fast algorithm for precise energy-loss calculations of high-energetic heavy ions
Motivated by the need of precise energy-loss predictions to identify heavy reaction products, several computer codes to calculate the energy loss of high-energetic heavy ions are tested. Some of them are found to deviate strongly, in some cases more than 10%, from the available experimental data. A new algorithm is presented which is particularly suited for technical applications. It combines h...
متن کاملThin Film Deposition Using Energetic Ions
One important recent trend in deposition technology is the continuous expansion of available processes towards higher ion assistance with the subsequent beneficial effects to film properties. Nowadays, a multitude of processes, including laser ablation and deposition, vacuum arc deposition, ion assisted deposition, high power impulse magnetron sputtering and plasma immersion ion implantation, a...
