Dania HefleyRon Noll Physical Science29 January 2018 Particle Accelerators There are more than 300,000 particle accelerators that are currently operating in the world.
What are particle accelerators, what are the used for, what do they even do? Particle accelerators have made such a great contribution to many fields of sciences. It’s hard to imagine where we would be in science without them. Who knew that particle accelerators are a step to time travel. A particle accelerator, or and particle collider are machines that take electrons and protons to higher energy levels. The machine crushes the subatomic particles. Particle accelerators are used to discover unknown things about the universe. Not only do particle accelerators accelerate the particles but it also makes the larger.The machine works with charged particles that are accelerated nearly to light speed.
As the particles get closer to light speed the accelerator gives them more energy to increase the particle’s kinetic energy and allow them to move faster.Particle accelerators have a wide variety of uses. Some scientist use the accelerators to study the origins of the universe and the subatomic structure of the world. Particle accelerators have helped advance research in many different fields. It’s very impressive the things the particle accelerator has done for evidence. Especially helping cancer patients with radiation therapy and tumor destroying beams.
Accelerators also help kill bacteria to prevent foodborne illnesses. Surprisingly particle accelerators have created better diaper parties and shrink wrap. It might be surprising to think but there might actually be a particle accelerator in your very own house. The CRT T.
V’s or even a computer monitor have cathode ray tubes that take the electrons and are sped up and change directions by using electromagnets. In a vacuum. Then what shows up on your screen are the smashed up particles that are turned into phosphorus molecules. CTR Particle accelerators have two beams that run around a tunnel in opposite directions.
Each beam travels in its own tube. Two things that all particle accelerators have even the ones in your living room are cathode ray tubes which are also known as vacuum tubes. These tubes shoot an electron beam at a fluorescent screen. The electrons collide with phosphor molecules and create the light we see on the screen.
Big scale particle accelerators are very similar just bigger and faster. There are actually two kinds of particle accelerators, linear also known as LINAC and circular. Linear accelerators propel particles in a straight beam and can also produce proton beams. Linear accelerators increase the kinetic energy of the subatomic particles by putting charged particles along a linear beamline. These accelerators are used for fixed target experiments. Linear accelerators are used a lot in medicinal sciences. They can generate x-rays and high energy electrons for medicine.
This accelerator creates radiation therapy for cancer patients. Its primary use in medicine is helping patients with cancer diseases. Circular accelerators move the particles in a circle until they have enough energy. This accelerator can be used for colliding beam experiments and fixed target experiments. The particle track is bent using dipole magnets.
An advantage to circular accelerators is that the parts can be used to further accelerate the particles because the particle passes a given point multiple times. A disadvantage of the circular accelerators is that the particles produce synchrotron radiation. Both of these accelerators accelerate the particles with an electric-field wave. This machine has made such a great contribution to science. Particle accelerators have become an essential tool for the discovery of particle and nuclear physics. It has also helped ask and answer basic questions about the universe.
Most importantly it has achieved the understanding of the fundamental particles and physics. Overall particle accelerators have made advances in so many fields.Something that would have never occurred to me is the theory that the Large Hadron Collider which is the biggest particle accelerator in the world might actually be able to be used as a time machine. This theory was created by Thomas Weiler and Chui Man Ho who have very strongly stressed that this is only a theory.
They have also stressed that if this theory were to be proven real that it would only be able to send particles and matter back in time and not human beings. This theory does not actually violate any of the “Law of Physics” so it could very well be proven to be real. The outstanding thing is that if this theory is right it can be used to send messages to the past and future. Space creates more powerful accelerators than the man-made ones on earth. The most energy filled cosmic ray was a proton accelerated to the energy of 300 million trillion electrons.
There has been no known source as powerful. Even though the accelerators on earth are not as powerful it is still very impressive all the things they have managed to achieve.
