Description

Crystals behave like a non-equilibrium medium (e.g. plasma), but at a relatively low temperature, if heated by a high-power driving source. The warm dense matter contains many more ions (n0 ~ 10^19 – 10^23 cm^-3) available for plasma acceleration than gaseous plasmas, and can possibly support electric fields of up to 30 TV/m of plasma oscillation [1 - 4]. Atomic lattice spaces in solid crystals are known to consist of 10 – 100 V/Å potential barriers capable of guiding and collimating high energy particles with continuously focused acceleration/deceleration by the exceptionally high electromagnetic fields. Nanostructured crystals (e.g. carbon nanotube) with dimensional flexibilities can accept a few orders of magnitude larger phase-space volume of channeled particles than natural crystals. Our PIC simulation results [5, 6] obtained from two plasma acceleration codes, VORPAL and EPOCH, indicate that in the linear regime (nb ≤ n0) the beam-driven and laser-driven electrons channeled in a 100 micrometer long effective nanotube gain 10 MeV (G = 1 – 10 TeV/m). Experimental tests, including slit-mask beam modulation and pump-probe electron diffraction, are designed in Fermilab and NIU to identify a wakefield effect in a photo-excited crystal.
