A particle accelerator is a machine that accelerates particles, such as a proton or electron, to extremely high energies. These particles are accelerated to about the speed of light and the only difference between a weak particle accelerator and a strong one is that the stronger particle accelerator’s particles will have more kinetic energy. All particle accelerators have the same 3 basic parts, a source of ions, a tube pumped to a vacuum where the particles can travel, and a way of speeding up the particles. The use of particle accelerators are good and can help scientist better understand the universe and subatomic particle relations.
Particle accelerators are good because they allow scientist to find new elements, how subatomic particles act, and give us a structured understanding of the universe. Particle accelerators are used to study the nature of matter and energy. These machines accelerate ions through an electric field where the ion collides with another particle or stationary object. Scientist then study these collisions attempting to explain interactions in the subatomic world.
Another reason that particle accelerators are good is because there are many different applications of particle accelerators in many different fields. Particle accelerators are used much more often than many people believe. A computer screen or television is really just a simplified particle accelerators and the collision of the particles results in a pixel on the screen. There are also many different uses in the medical field, one form of cancer treatment is the use of a particle beam and hospitals use this to treat patients with far fewer side effects that traditional treatment options. Another medical tool that is used very often is an X-Ray...

Nuclear energy is used today for energy supply and about 15% of the world’s energy comes from nuclear power plants some forms of medicine such as nuclear medicine rely solely on nuclear technology. This technology was developed through the process of creating the first atomic bomb and would not exist if not for the advancements made during the Manhattan project.
Physicists found out that among the pieces of a split atom were newly produced neutrons. These might encounter other uranium nuclei, cause them to split, and start a chain reaction. If the chain reaction was limited to a moderate pace, a new source of energy could be the result. The chain reaction could release energy rapidly and with explosive force. Leo Szilard, Eugene Wigner, and Edward Teller, Hungarian-born physicists, were frightened by the possibility that Germany might produce an atomic bomb.

After the United States developed the atomic at the end of World War II, interest in nuclear technology increased exponentially. People soon realized that nuclear technology could be used for electricity, as another alternative to fossil fuels. Today, nuclear power has its place in the world, but there is still a lot of controversy over the use of nuclear energy. Things such as the containment of radiation and few nuclear power plant accidents have given nuclear power a bad image. However, nuclear power is a reliable source of energy because it has no carbon emissions, energy is available at any time, little fuel is needed for a lot of energy, and as time goes on, it is becoming safer and safer.

Antimatter rockets were proposed in the early 1950s by a German scientist, Eugen Sanger. This rocket would have a speed of about 3×〖10〗^7 m/s . It would produce “energetic gamma rays” which causes to travel about the speed of light (Mallove, 49).
From scientific breakthroughs that revolutionized our understanding of the world to practical inventions that changed the way we live, scientific and technological developments in the 20th century have profoundly altered nearly every aspect of our lives. We usually think of these changes as wholly positive, but when you look at the destruction caused after the first two atomic bombs were dropped on Japan in 1945, this view tends to be distorted. As we can see by this horrific event, technology can be used to improve lives, but also destroy them.
Operating the largest machine in the world won’t be essay. The collider has two functions, it is to accelerate particles to high speeds in a beam that is about 2mm wide and then to direct the beams to the heart of the collider, where the head-on collision takes place. The particles that the Hadron collider accelerates are protons and lead nuclei; these have positive charges and so can be steered by magnets. These super magnets (9,300 in total) are used to control and steer the particles as they make their way around the 27km loop of the Large Hadron Collider. The Hadron Collider actually has two beams which travel opposite to each other so two sets of protons can travel towards each other. At the heart of the collider, the two beams meet for a brief moment, and that’s where the things go bang! This is where the explosion takes place and where the scientist, can try to find new elements.
The year 2012 was not only memorable to physicists for its breakthroughs, which include the galaxy motion cluster, neutrino-based communication or the method to see through opaque materials. But it is memorable because 2012 was the year that the physicists working in the Large Hadron Collider announced the detection of the Higgs boson particle.
We stand at the base of a new age. We are just now beginning to learn the intricate details of life, both macroscopic and microscopic. Ultimately these discoveries will benefit all of mankind. Never before have we enjoyed such a golden age for science and discovery. The scientific horizon looks fruitful. One such fruit is the discovery and application of a thing called antimatter. During the next few decades our ability to produce, accumulate, and contain large quantities of antimatter should become feasible, leaving us just to research possible uses for this promising, radically new, form of energy.
...h cesium ions and then to focus it into a fast moving beam. The ions that are produced become negative, which helps prevents the confusion of Carbon-14 with Nitrogen-14 since Nitrogen does not have a negative ion. The first magnet is used to select ions with an atomic mass of fourteen. The ions then enter the accelerator. As they travel to the terminal, they are accelerated to an incredible speed so when they collide with the gas molecules, all of the molecular ions are broken up and most of the carbon ions have four electrons removed, turning them into Carbon3+ ions. The second magnet selects ions with the speed expected for the Carbon-14 ion and a filter makes sure their momentum is also right. Finally, the filtered Carbon-14 ions enter the detector where their speed and energy are checked so that the number of Carbon-14 ions in the sample can be counted (Oxford).
The Industrial Revolution sparked a need for large sources of energy. Human and animal labor could not provide the power necessary to power industrial machinery, railroads, and ships. The steam engine and later the internal combustion engine provided the bulk of the energy required by the industrial age. Today most nations are still heavily reliant on energy that comes from combustion. Usually coal, petrolium, and natural gas are used. Some hydroelectric, wind power, and nuclear fission sources are used, but in the US they accounted for less than 20% of the total energy consumption in 1997 (1). Many experts are worried that natural resources such as coal and petrolium are being depleted faster than they are being replenished, which could result in an energy crisis. Nuclear fission produces highly radioactive waste that is expensive to dispose of properly. Nuclear fusion reactors would produce much less radioactive waste and would be more efficient than nuclear fission, but to date there have been no nuclear fusion reactors that have generated usable energy output. Why is fusion power, which could be very beneficial, so hard to come by?
In conclusion, gamma rays, I have learned, are dangerous but sometimes useful. There has been a great deal of research put into studying gamma rays and gamma ray radiation. Gamma rays have a tremendous amount of energy and their wave lengths are very small. I would have never thought there was something like gamma rays that could cause cancers.
