Wee accelerators?
That's taking the pi$$....
Forget about mounting your lasers on the nearest shark, what you really want is a laser plasma accelerator you can put on your kitchen table. Scientists at the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have managed to create powerful electron beams from much, much, much smaller accelerators …
the comparison with the Large Hadron Collider - «doing the sort of research the Large Hadron Collider is doing right now» is misleading if taken literally. According to the «Nature Physics» abstract, «[t]he technique relies on a single laser pulse powering a plasma structure with a tailored longitudinal density profile, to produce beams that can be tuned in the range of 100– 400 MeV with per-cent-level stability, using laser pulses of less than 40 TW». The LHC, on the other hand, is designed to reach energy levels of some 7 TeV, or about 18-70 thousand times greater. So it seems unlikely that they'll be filling in those 27 km of tunnels on the Franco-Swiss border with landfill just now....
