[QUOTE]Today the Linear Collider Collaboration published its five-volume [URL="http://ilcdoc.linearcollider.org/record/41121/files/ILCTDR-VOLUME_1.pdf"]Technical Design Report[/URL] for the International Linear Collider (ILC) - a proposed 31-kilometre electron-positron collider that will both complement and advance beyond the physics of the Large Hadron Collider.
The Technical Design Report presents the latest, most technologically advanced and most thoroughly scrutinised design for the ILC.

Here come the doomsday theories.
Why linear I wonder, a ring collide enables you to make more laps to gain more speed. Though there seems to be able to turn particles I would have though a gradual rather then a sharp turn is better. I'm just thinking the magnetic field required to turn a particle in a small radius travelling at <0.999c is ridiculous

Seem I'm wrong, they can't loop then around continuously
Nintendo should license the designs for Super Mario Kart tracks. Add an exclusive power-up to accelerate to nearly the speed of light.

Causing you to crash violently into the wall because you'll have literally no time at all to react to any turns whatsoever making for a very tragic and frustrating game AND funeral for the poor chap who has to use the power-up.

It's been a while, but I think a linear accelerator enables them to find stuff they couldn't before. Can't remember whether it's simply about energy or something else.
For a second I thought they were going to build a football field off to the side for fun.

Looks a bit like a Mass Relay
Come on CERN, the boson is cool and all, but a Relay would be much cooler

The whole "particle that determines mass" thing always did remind me of eezo.
Biotics, make it happen science.
Can't wait for accelerators that can break the Greisen–Zatsepin–Kuzmin limit :v:.

CERN probably should have consulted you first I guess.

You realise Facepunch is a site where only post-docs who know best post? All those silly particle physicists and engineers at Geneva are amateurs, top lel.

The higgs boson doesn't determine mass, it's an extra excitation in the higgs field. The interaction of particles with the higgs field is what creates mass (supposedly; We don't really know very much about the subject right now).

I don't understand why they haven't accepted my idea for a scribble shaped particle collider. Between that and my government Rhombus rumpus building to replace the Pentagon it's my best idea.
[QUOTE=Yahnich;41007291]because out of the simple relation a = mv²/r we can see our acceleration and speed are limited by the radius of the circle the particle traverses due to the centripetal force (this is an oversimplification, there's also the magnetic fields etc that have to be accounted for but that's the basic gist)
a linear particle accelerator only has to account for the lorentz force and the speed and acceleration are only limited by the magnetic/electric field[/QUOTE]
More importantly, [url=https://en.wikipedia.org/wiki/Synchrotron_radiation]charged particles radiate energy when they are accelerated[/url].
This means that in a synchrotron it's necessary to add energy to maintain speed, unlike in a linear accelerator.

I'd suspect a Newtonian physical equation wouldn't stand up here but I'll pass over that.
It's a bit more complex than simply moving a particle through an electric field here to accelerate it. We're talking energies in the GeV and upwards range. Assuming an electron, you can't just place two screens for the particle to travel though then apply a few hundred giga-volts to it, such a voltage is unfathomable. Even if you have hundreds or thousands of these screens to pass the particle though along the length of the accelerator it's still ridiculous. The advantage of a circular accelerator is you can make thousand, tens of thousands, hundreds of thousands or more passes over and over again.
There has to be more than that

Looking it up it seems Linear particle accelerators work better for heavier particles

Capacitors don't work like that, the particle would be returned to its original velocity after passing the system because the potentials balance each other in the distance in both ways.
A better way to accelerate particles is to use dynamic field (from (micro)waves). That way large voltages can be avoided and it's easier to control the speed of the electrons.

I don't know where you pulled capacitors from.
Anyway, you turn the grids on and off

I see what you mean now though.
