conventional x-ray machine. When a charged particle accelerates it radiates photons or x-rays. For example‚ in a conventional x-ray tube the electron beam accelerates from a fila ment to an anode‚ where it decelerates rapidly at the anode and emits x-rays (shown schematically in Fig. 2). A different approach is to accelerate (or decelerate) the particle by passing it through a magnetic field. This is what really happens in an accelerator. When the particles curve in the magnetic field‚ x-rays are emitted

determine how the numbers of simulated particles‚ inhomogenities in the medium and the voxel size affect the simulations ability to calculate dose‚ as well as to understand the effects of cutoff energy on the Monte Carlo simulation (MC). Particle interactions are the cause of everything we know to exist‚ such as the bright lights that illuminate the room you are in or the heat you feel when you stay in the sun for too long. To understand how these particle interactions occur we need to be able to

Non-existent? Pentaquarks‚ Elusive or Non-existent? Outline: Beginning in 2003‚ scientists claim to have experimental evidence of a five-quark combination‚ and it is now being called a pentaquark. Pentaquarks are postulated subatomic particles consisting of four quarks and one antiquart. Scientists that have done research believe it to exist; others are doubtful skeptics that are against its existence. I. Introduction of Pentaquarks A. Definition B. Picture explanation II. History

neutrinos are‚ how they were discovered and the experiments that are conducted to learn more about them. I learned that neutrinos are subatomic particles with a zero charges and very little mass. There are three types of neutrinos: electron‚ muon and tau. The idea that neutrinos exist was proposed by Wolfgang Pauli. He proposed that there were more than two particles involved in an explosion‚ that along with protons and electrons‚ that a third‚ the neutron‚ was also involved. He stated that energy and

The actual definition is the emission of high energy particles or waves. This can mean many things‚ but the two most common are electromagnetic waves (photons)‚ or high energy particles released from decaying atoms. The one that I will be talking about is radioactive atoms (the green things that glow in the dark). This kind of radiation is called nuclear
