Progress in acceleration of particle is quite steady but slow, at least in my opinion. I was wondering what are the fundamental roadblocks to develop larger electric fields gradients (in any material) to accelerate and large magnetic fields to keep particle in round trajectory for storage/collision.
Electric and magnetic fields end up limiting the achievable energies in particle accelerators and I wanted to know what are the fundamental limits to them in ordinary (metals, liquids, ... ) and extra-ordinary materials (plasma, lasers, rare metals from planet Krypton ...)
I can certainly see how
materials imperfections can : 1) lead to instabilities such as discharges from sharp objects, or 2) get amplified and give rise to alterations of the materials due to a too strong magnetic field, that would start messing up the lattice structure of a metallic magnet (or anything similar at a larger length scale)
I am sure there is much more to say ... thanks for your inputs!
