Hi my question is simple, can we make the protons stay in a fixed position (not accelerating them) in LHC by using the powerful magnets there?
Thanks
Thanks
You would lose them in the process - slowing down means blowing up their bunch size and then they don't fit in the narrow parts of the beamline any more.Vanadium 50 said:In principle, I suppose you could run the accelerating RF in reverse, which would take a minute or two to get the protons moving slowly.
?wifirex said:And if not in a vacuum (for example if one shone a torch on it), would it be quickly be bombarded by other protons back to its original speed?
The mass of a proton is always the same.

They are the same particles, but of course there are differences when they are moving. If a moving car hits you it is the same object as a car at rest, but the result is different.wifirex said:I wanted to know if protons behave differently when they are at rest compared to when they are moving.
No.wifirex said:then wouldn't they split the kinetic energy and then both be traveling at 1/2 the speed of light?
Not by a beam, by a single collision. Yes. Again, this has a classic analog: a car at high speeds crashing into a car at rest leads to an accident as well.wifirex said:Lastly back to the LHC - can a proton at rest truly be shattered by a beam of protons?
No, it is not possible to completely stop protons from moving in the LHC. The LHC is a particle accelerator designed to accelerate protons to very high speeds, close to the speed of light. Stopping the protons completely would defeat the purpose of the LHC and its experiments.
Scientists use powerful magnets to control the movement of protons in the LHC. These magnets are strategically placed along the LHC's circular tunnel and are used to accelerate, steer, and focus the protons as they travel in opposite directions.
The LHC is used to study the fundamental building blocks of matter and the interactions between them. By keeping the protons moving at high speeds, scientists can recreate the conditions of the early universe and study the behavior of particles at these extreme energies.
Yes, it is safe to have protons moving at high speeds in the LHC. The protons are contained within a vacuum tube and the LHC is designed with multiple safety systems in place to ensure the safe operation of the machine.
Yes, the LHC is equipped with emergency stop systems that can quickly shut down the machine in case of any potential hazards. These systems are regularly tested and monitored to ensure the safety of the LHC and its operators.
