Particle accelerators use electric fields to speed up and increase the energy of a beam of particles, which are steered and focused by magnetic fields. with other types of accelerator, such as betatrons and microtrons. More exotic particles, such as protons, neutrons, heavy ions and negative p mesons, all produced by special accelerators, are also sometimes used for radiotherapy; however, most contemporary radiotherapy is carried out with linacs or teletherapy cobalt units. 7.

A bend Se hela listan på accelerators-for-society.org The electron linear accelerator (linac) accelerates charged particles in a straight line, in contrast to the circular or racetrack orbits that characterize the cyclotron and synchrotron. The purpose of this primer is to explain the principles of opera-tion and use of the electron linear accelerator and to acquaint the reader with pertinent features and Introduction Particle accelerators, such as linear accelerator (LINAC) and cyclotron systems, increase the kinetic energy of particles for use in a variety of applications, ranging from scientific studies on particle physics to radiation therapy for cancer patients. In a linear accelerator (LINAC) the charged particles are accelerated in a straight line (whereas in a circular accelerator magnetic fields are used to move the particles in a circular trajectory - see the cyclotron next). The diagram below shows the principle of operation of a LINAC.

A linear particle accelerator functions to increase the velocity of charged subatomic particles or ions, by subjecting the charged particles to a series of oscillating electric potentials along a linear beamline. Advanced electronics are used to precisely control the rate of electron emission. for Linear Accelerators Melissa Martin, MS, FACR, FAAPM, FACMP Therapy Physics Inc., Gardena, CA 90248 Melissa@TherapyPhysics.com AAPM 51st Annual Meeting Anaheim, CA July 27, 2009 Page 2 Key Messages in This Presentation Each linear accelerator vault is unique Challenges in generating a shielding report
