Particle accelerators are awesome. The Large Hadron Collider is amazing. However, what will we be using 100 years from now in terms of what particle accelerators do?

 

Mainly 1.) what would they do? What could they create or achieve?

 

2.) How big would it be?

 

3.) Whats a good name to call it?

One option for advanced particle accelerators would be a Wakefield Accelerator, with the main advantage being much higher acceleration over the same length compared to a conventional one. The link explains it in more detail.

 

Now my personal favourite would be a Circumsolar Particle Accelerator, but a 100 years seems too early for such a device. The Book Death’s End introduced this idea to me.

 

1. Such an accelerator might be used to for the unification of forces. One with a radius of 1 AU might operate at 4.5*10^11 GeV, as compared to the LHC’s 7 TeV.

 

2. In terms of scale such a device would be overwhelming: If you were to put it in an orbit just past Earth it would have a diameter of > 300*10^6 kilometres. Keep in mind that it would most certainly not be built as a solid ring.

 

3. Circumsolar Particle Accelerator seems just fine. It’s so big it deserves a long name. If you aim for flashiness call it Halo Veritas or something along that line.

Particle accelerators IN SPACE are the next big thing. As this paper apparently discusses, beyond 100 TeV, space-based particle accelerators become more practical than ground-based ones. As the timeline discusses, the 100-TeV Future Circular Collider will last until 2075, so the 2070s seem like a good bet on when to start building something in space. When you take into account much cheaper launch tech, it'll probably be a project on the scale of the ISS, with construction running into the 2090s before it's turned on.

 

As discussed here, it would likely take the form of a series of magnets in geostationary orbit. No need for fancy tubes since space is already a vacuum and it's easy to maintain cryonic temps out there.

 

A few hundred years further on, you could get a similar setup out in the asteroid belt, with a lot of magnets planted on little asteroids. A few hundred years after that? Well. Interstellar comets are a lot more common than you'd think. Stick magnets on a few million of those in a giant circle a couple light years across, give them some decent AI so they can figure out where the next comet even is, and you're golden.

 

Space is good for particle accelerators, because you can dispense with the tubes and just keep the stuff that matters.

 

There are also portable laser particle accelerators that are also very powerful, those are eventually going to be common in university labs.

A tube around the Earth in low orbit, called HALO (Hadron Accelerator in Low Orbit) :D


“If the genius of invention were to reveal to-morrow the secret of immortality, of eternal beauty and youth, for which all humanity is aching, the same inexorable agents which prevent a mass from changing suddenly its velocity would likewise resist the force of the new knowledge until time gradually modifies human thought.”

No tube, just magnets. There's already a vacuum. And LEO is too crowded with stuff.
