It's 10 Tesla magnets that are called ridiculous. The paper also requires 1000 TeV, not 100.

Current record for magnets: 45 teslas.

They need enough for 1000km of accelerator though. LHC has 10,000 superconducting magnets for 26.7km (some can temporarily go up to 7.7 Tesla).

There's more than just raw strength that goes into making magnets for a collider. It's the combination of strength, uniformity, and enclosed volume which makes things difficult.

Oh, blame my reading comprehension skills then
