INERTIAL CONFINEMENT FUSION
1. Introduction / Beginnings
In the 1940s during the development of nuclear explosives, the
inertial confinement approach to fusion was born. Weapons
researchers determined that by use of high energy sources, such as the
fission reaction, light nuclei could be fused, thus creating intense fusion
energy. Scientists in the controlled fusion camp also realized that tight
compression of fuel pellets could increase the fusion reaction rate
which is proportional to fuel density. (Robert A. Gross, Fusion
Energy, New York: John Wiley and Sons, 295)
Scientists were, at this stage, trying to discover a mechanism which
could compress a light-nucleus fuel. The invention of high power lasers
encouraged the inertial-confinement camp. The radiation from the
laser heats a fuel pellet, and as the plasma from the pellet rapidly expands,
a momentum reaction sends compressive waves inward,
converging on the pellet's core. The energy in the core causes the ignition
of the pellet. The common desire is to obtain a thermonuclear
energy yield that exceeds the energy which is required
to heat and compress the solid before the pellet explodes;
hence the name inertial confinement. Some of the early research in this
subject was done by Nuckolls and Kidder of the Livermore Laboratory,
and Bosov and Krokhin of the Kurchatov Institute in the
USSR. (Gross, 295)
Since these great efforts, the scientific community has considered
inertial-confinement fusion to be the top alternate method for controlled
thermonuclear fusion. The most probable containment, of
course, is magnetic confinement fusion. Tokamak Fusion Test
Reactor (TFTR) in Princeton, New Jersey is argueably the premier

...died; however, the heavy-ion accelerators show much promise in its
short time of consideration. Laser light coupling and laser efficiencies have
been a problem for laser-driven designs. Ion-driven devices
have problems of their own, particularly in focusing to the required power
density. (Dean, 75) The HYBALL-II project as well as other ICF
projects today have easily surpassed the yields of the early ICF
reactors (SOLASE). In the big picture, however, one should keep in mind
that magnetic-confinement devices show much more promise at
this point.

Introduction Fusion centers are easily described by their names. They are a collaboration between several different agencies that combine to form one united Criminal Justice front against terrorism. All agencies, such as the FBI, Department of Homeland Security (DHS) and local police, work together to analyze and gather potential information on threats and possible terrorist attacks against the United States. They also serve as a sort of hub to pass out information needed to other agencies. The creation of Fusion Centers helps make local law enforcement more capable in responding to and fighting terror threats.
Albert Einstein predicted that mass could be converted into energy early in the century and was confirmed experimentally by John D. Cockcroft and Ernest Walton in 1932. In 1939, Otto Hahn and Fritz Strassmann discovered that neutrons striking the element uranium caused the atoms to split apart. Physicists found out that among the pieces of a split atom were newly produced neutrons. These might encounter other uranium nuclei, caused them to split, and start a chain reaction. If the chain reaction were 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.
The Trinity Project was a project conducted to test the effects of a nuclear weapon. The Trinity nuclear device was detonated on a 100-foot tower on the Alamogordo Bombing Range in south-central New Mexico at 0530 hours on 16 July 1945. (Rohrer, 1995-2003). This project was organized by the Manhattan Engineer District (MED). This organization worked diligently planning and coordinating all of the logistics for the groundbreaking event. From 1945-1946 over 1000 personnel either worked or visited the test site. The United States was trying to gain nuclear proliferation throughout the world so this project was necessary for our enemies to see the devastation of a nuclear blast.
Second, the potential amount of energy produced by fusion can greatly outweigh the fission. Initially, there are some disadvantages to fusion. The time and money required to develop technology needed to initiate, contain, and sustain a profitable fusion reaction is costly, but the development is still in its early stages and will continue to advance through the next century. Fission readily creates a chain reaction which must be slowed through use of a moderator to avoid core meltdown, while fusion can only be accomplished at temperatures similar to the centre of stars, about 100 million degrees celsius. The components used in fusion exist in the form of plasma where atoms are divided into electrons and nuclei.
In 1949, the U.S. was shocked when the U.S.S.R. was able to successfully reproduce a nuclear missile, when, the U.S. had been carefully guarding the plans for the missiles. The missiles continued to improve when, in January of 1950 a German theoretical physicist named Klaus...
Fusion centers were created under President George W. Bush after the terrorist attack on the World Trade Center in New York on September 11, 2001. The objective of the fusion centers was to form a collaborative partnership between varied representatives of the local, state, and federal government along with participants of diverse disciplines according to Arena & Arrigo (2005).The mission of the members was to gather, analyze, and share critical information relating to terrorist threat that came into the fusion centers ( Carter, 2004). The centers informed law enforcement agencies of potential terrorist threats, which could significantly impact infrastructures around the world states Johnson & Dorn (2008). Currently,
It was Italian-born physicist and Nobel winner Enrico Fermi, and his colleagues at the University of Chicago who were responsible for this success (“Nuclear”).

To power such high-energy lasers, SDI researchers had to develop a new, more powerful type of power. The Multi-megawatt, or MMW, was the main focus for power. During most of the 1980’s the SDI’s MMW Space Nuclear Power Program was the first major focus for work on the high-power open and closed cycle reactors. The work on the nuclear power systems, conducted by the Energy Department under the SDI program, was complemented by the Air Force investigations of non-nuclear power concepts.

Whilst there are clear arguments for and against nuclear energy, the future is promising; with scientists working on potential breakthroughs such as nuclear fusion, and the design of newer and better and reactors. Nuclear fusion is a reaction which causes the nuclei of atoms to collide and form a new atomic nucleus. It is essentially what heats the sun and stars and would produce no long-lived radioactive waste.22 If scientists could control the process of atomic fusion then it could become a never ending energy source for future use.
