Photon and electron spins.
It is easy to draw an intuitive parallel between the classical free electromagnetic field and its corresponding quantum, the photon-a spin-1 object. The situation with a massive particle such as an electron is less clear, as a real-world analog of the classical field whose quantum is the massive particle is not available. It is concluded that the fermion particle perspective provides the best a...
متن کاملMeasurements of Photon Beam Flattening Filter Using an Anisotropic Analytical Algorithm and Electron Beam Employing Electron Monte Carlo
Introduction: This study aimed to report the measurement of photon and electron beams to configure the Analytical Anisotropic Algorithm and Electron Monte Carlo used in clinical treatment. Material and Methods: All measurements were performed in a large water phantom using a 3-dimensional scanning system (PTW, Germany). ...
متن کاملEvaluation of Electron Contamination in Cancer Treatment with Megavoltage Photon Beams: Monte Carlo Study
Background: Megavoltage beams used in radiotherapy are contaminated with secondary electrons. Different parts of linac head and air above patient act as a source of this contamination. This contamination can increase damage to skin and subcutaneous tissue during radiotherapy. Monte Carlo simulation is an accurate method for dose calculation in medical dosimetry and has an important role in opt...
متن کاملReduction of photon contamination in electron therapy of cancer with magnetic fields
Introduction: Photon contamination is a restriction on treatment with electron that increase dose to healthy tissue below the tumor. The aim of this study is to reduce the photon contamination using a magnet system. Materials and Methods: A mini-applicator equipped with two neodymium boron permanent magnets was designed which make it possible to adjust the d...
متن کاملHigh Energy Photon-photon and Electron-photon Collisions *
The advent of a next linear e ± e − collider and back-scatterd laser beams will allow the study of a vast array of high energy processes of the Standard Model through the fusion of real and virtual photons and other gauge bosons. As examples, I discuss virtual photon scattering γ * γ * → X in the region dominated by BFKL hard Pomeron exchange and report the predicted cross sections at present a...
