Is 40,000 joules of energy enough for Nuclear fusion?

In summary, the conversation discusses the possibility of using the OMEGA laser at the LLE in Rochester to concentrate two particles and force them to fuse with 40,000 joules of energy. However, the challenge lies in containing the energy in a small enough volume, as the deuterium-tritium fusion reaction requires a temperature of 141 million K.

Is -4 enough to make the sky blue?

You've certainly not given enough information for anyone to make sense out of your question.

Fusion of what? Hydrogen? What does 40,000 joules represent? The average thermal kinetic energy of the particles?

yeah, sorry about that. I was just wondering if the LLE in rochester could use their OMEGA laser to concentrate two particles and force them to fuse. the OMEGA laser can direct 40,000 joules of energy though a colaboration of 60 lasers.

Urban: yes.

The problem is getting that energy into a very small volume and keeping it there.

The deuterium-tritium (D-T) fusion reaction requires the lowest temperature to ignite -- 141 million K, which is 12.1 KeV or 1.94 x 10-15 joules per nuclei..
 

1. Is 40,000 joules of energy enough for Nuclear fusion?

The short answer is no, 40,000 joules of energy is not enough for nuclear fusion to occur. Nuclear fusion requires much higher energy levels, on the order of millions of joules, to overcome the strong electrostatic repulsion between atomic nuclei and create the necessary conditions for fusion to take place.

2. How much energy is needed for Nuclear fusion to occur?

The amount of energy needed for nuclear fusion to occur depends on the specific elements involved. Generally, it takes several million joules of energy to overcome the repulsive forces and initiate fusion. For example, the fusion of two hydrogen nuclei to form helium requires about 3.2 million joules of energy.

3. Why is so much energy needed for Nuclear fusion?

Nuclear fusion is a process in which the nuclei of two atoms combine to form a larger nucleus. This process releases a large amount of energy, but also requires a significant amount of energy to overcome the strong repulsive forces between atomic nuclei. This energy is needed to bring the nuclei close enough together for the strong nuclear force to take over and bind them together.

4. Can nuclear fusion occur with less than 40,000 joules of energy?

No, nuclear fusion requires much higher energy levels than 40,000 joules to occur. This amount of energy is not enough to overcome the repulsive forces between atomic nuclei, and therefore fusion would not be possible at this energy level.

5. What are some real-life examples of nuclear fusion?

Nuclear fusion reactions occur naturally in stars, including our own sun. In addition, scientists are working on replicating nuclear fusion on Earth for potential use as a clean and abundant source of energy. One example of this is the International Thermonuclear Experimental Reactor (ITER) project, which aims to create a fusion reaction that releases more energy than it consumes.
