A multi-scale approach to the physics of ion beam cancer therapy
We propose a multi-scale approach to understanding physics related to the ion/proton-beam cancer therapy and calculation of the probability of the DNA damage as a result of irradiation of patients with energetic (up to 430 MeV/u) ions. This approach is inclusive with respect to different scales starting from the long scale defined by the ion stopping followed by a smaller scale defined by secon...
متن کاملPhysics of ion beam cancer therapy: a multiscale approach.
We propose a multiscale approach to understand the physics related to ion-beam cancer therapy. It allows the calculation of the probability of DNA damage as a result of irradiation of tissues with energetic ions, up to 430 MeV/u. This approach covers different scales, starting from the large scale, defined by the ion stopping, followed by a smaller scale, defined by secondary electrons and radi...
متن کاملNano-Scale Lateral Milling with Focused Ion Beam for Ultra-Smooth Optical Device Surface
The effect of the nano-scale lateral milling process using a focused ion beam (FIB) was studied in order to prepare a flat and smooth surface suitable for the growth of optical device structures such as a distributed Bragg reflector (DBR) mirror on a rough gallium nitride (GaN) surface. A high-quality, smooth, and flat surface is very essential for high precision space optics. It was fabricated...
متن کاملIon-beam machining of millimeter scale optics.
An ion-beam microcontouring process is developed and implemented for figuring millimeter scale optics. Ion figuring is a noncontact machining technique in which a beam of high-energy ions is directed toward a target substrate to remove material in a predetermined and controlled fashion. Owing to this noncontact mode of material removal, problems associated with tool wear and edge effects, which...
متن کاملIon-Beam Induced Nano-Sized Ag Metal-Clusters in Glass
Silver metal clusters have been formed in soda lime glass by high-energy heavy ion diation at ISL. The metal cluster formation was detected with X-ray absorption spe copy (EXAFS) in fluorescence mode, and the shape of the clusters was imaged transmission electron microscopy. While annealing in reducing atmosphere alone a leads to the formation of metal clusters in Ag containing glasses, where t...
