The design of a next generation of colliders is already under way to replace the LHC using a fundamentally different approach.

Besides the differences in design, it will smash mater and antimatter together creating a much bigger bang for the buck.

There are competing projects

Just a few weeks ago a major development occur towards these devices

Nice story on the future of colliders beyond the LHC

They have no idea what they'll find in the LHC and they already plan to build something bigger? I wish they waited and didn't try to rush into building another collider so soon.

The LHC took about 20 years from the first plans until now but the main experiments of the LEP were only about 15 years ago.
So that is onlynrmal to think already about the next step.

I think it is good idea to start planning next one, while the experiances of building this one are still fresh in their minds, and the people who built it are still around to suggest improvements for next time.

Then they can add the improvements from the 'operations' side in 5 year or so time.

From the first accelerators there have always been plans for the next one and even the one after that.. Thats how it works. It does indeed take 20 years to plan and build these things, so you gotta start yesterday.

What is the equivalent energy in TeV to the 10^20 cosmic rays observed?

100 000 000 TeV is 10e20 eV, so they're just a bit more powerful than the LHC...

Wow, so they mean it when they say cosmic rays "are much more powerful". I didn't think the difference is that high. Thanks for the clarification.

As I understand it the LHC and hadron colliders in general are 'discovery' machines that use brute force to generate new heavy particles but have large uncertainties as to how much energy went into creating the observed tracks hence the need for very large data sets so statistics can be applied. A linear collider using leptons (Electrons +/or Positrons) that can have the collision energy finely controlled and known gives greater precision in the measurement of the particles properties.

So they make big messy collisions in the LHC and hope to find something by sifting through the debris. When they do find something it will take another machine with scalpel like precision to completely explore the fine detail of it's properties.

This is the group that is trying to build it;

PS a good lecture on the ILC;

The new set of collider like the linear doesn't sound too bad, but the theoretical collider in the "far future" sounds scary and a bit risky.

Don't worry too much stephen this is all well u know, lets just say I cant see funds being commited until the LHC produces something else to explore then we will once again understand the forces involved to go to the next level, its much slower and "safer" if u like, especially compared to the SSC which was i feel was only given the green light to blow the LHC out of the water:
