Why don't we put particle accelerators in a Jet?

In summary, the idea of using a jet aircraft to increase the velocity of particles in an accelerator is impractical due to the low mass of the particles compared to the jet and the non-linear addition of velocities at high speeds. It would be more effective to mount a particle accelerator on a spacecraft with an ion engine, but even this would require substantial distance and fuel to achieve high speeds. The concept of attaching a gun to a snail or a person to increase their velocity is flawed as it goes against the laws of motion.

the velocity of the jet will add to the velocity of the particles , so they will be have greater velocity right?

But then the thing we are colliding them with would also be on a jet...

Besides, how could you fit a particle accelerator on a jet? And, have you calculated what % increase in velocity doing all this would net you? The particles are going very fast. Jet speed is virtually nothing compared to them. Might as well put a gun on a snail to increase the bullet's velocity.

lol makes sense now , i though i had a genius idea

The speed of a jet aircraft (less than one km/sec) isn't even a rounding error compared with the speed of particles in an accelerator (300,000 km/sec). It would make more sense to increase the effectiveness of an anti-tank gun by mounting it on the back of a tortoise.

The LHC main tunnel is 17 miles in circumference and the helium-4 cooling its magnets weighs 96 tons alone. The magnets themselves weigh over 43,000 tons. I'd like to see that thing fly.

The secret is we must create very fast and powerful jet planes. Good luck!

Velocities don't add linearly at high speed like they do at low speed. So even if you could put a particle accelerator on a plane, it wouldn't accomplish anything.

I think OP was not talking about a collider (going in circles and ending in a cancelling collision) but rather an open ended one so the great velocity of the particles would be a reaction engine.

I think this analogy is backwards in that the Jet is the Snail and the Bullet is The Particles. Attaching a gun to a snail and firing it most likely would accelerate the snail! :biggrin: The great difference is that the bullet has substantial mass relative to the snail. In the case of the Jet, the particles have many orders of magnitude lower mass than the Jet - ineffective in a planet's gravity and atmosphere.

However, once in Open Space, this changes. While the link is not exactly a particle accelerator on the scale of LHC, it is instructive. Here - http://www.nasa.gov/centers/glenn/about/fs21grc.html. These so-called Ion Engines can attain astounding end speeds (probably what fueled OPs idea) but the acceleration is slow to build due to the low mass of the ejecta. They require no counter-acting forces and great distances within which to build up to the speed of the ejecting ions.

Thus an Ion Engine propelled rocket can not launch from the ground. It would just sit on the pad. Some other form of power is required to achieve escape velocity against the mighty pull of Earth's gravity. Assuming there could be a reasonable power source for using a typical particle accelerator used for colliding experiments in an open-ended fashion, it could potentially achieve very high speeds, given enough room to build it up, and enough fuel to continually power it versus the added mass of the power source and it's fuel.

Back to the Snail and the Gun, like most chemical engines, the gun has explosive power - very substantial pressure and mass released in a sudden burst. This creates rapid acceleration for a short term but very low velocities relative to accelerators. Our chemical rockets behave much like this with the exception of not throwing some great mass, depending totally on a sustained reaction.

If you notice that the acceleration from the gun behaves on the snail almost instantaneously, while a chemical rocket lifts very slowly at first from the pad, gathering speed over time, and then continue in that direction at some far "distance down the line" we come to particle acceleration engines and you can see how these would be impractical on planet bound Jets traveling very short distances against great forces.

And attaching it to a person would accelerate the person too (and whatever that person manages to stay attached too). You can't get around Newton's laws here. If the bullet is going to change momentum that which pushes on it must change momentum. But on a moving object, snail or otherwise, the bullet will have a velocity before being fired that will result is a slightly faster initial velocity with respect to the ground.

1. Why don't we put particle accelerators in a Jet?

Putting a particle accelerator in a jet would be extremely difficult and impractical. Particle accelerators are large and complex machines that require a lot of energy and precise control. A jet would not have the necessary space or stability to accommodate such a device.

2. Would a particle accelerator in a Jet make it more powerful?

No, a particle accelerator in a jet would not make it more powerful. Particle accelerators are used to accelerate subatomic particles to high speeds, but this does not translate to increased power for a jet. In fact, the added weight and complexity of a particle accelerator would likely decrease the jet's performance.

3. Could a particle accelerator in a Jet be used as a weapon?

No, a particle accelerator in a jet would not be a practical or effective weapon. Particle accelerators are used for scientific research and have no practical use as a weapon. Additionally, the technology and infrastructure required to operate a particle accelerator would make it impossible to use in a jet for military purposes.

4. Would a particle accelerator in a Jet be dangerous for passengers?

Yes, a particle accelerator in a jet would be extremely dangerous for passengers. Particle accelerators produce high levels of radiation and require strict safety protocols to operate. Placing one in a jet would expose passengers to dangerous levels of radiation and could have serious health consequences.

5. Could a particle accelerator in a Jet be used for space travel?

No, a particle accelerator in a jet would not be suitable for space travel. Spacecraft require a specific type of propulsion system that allows them to travel in the vacuum of space. Particle accelerators are not designed for this purpose and would not be able to provide the necessary thrust for space travel.
