  Crystal channeling technology has offered various opportunities in the
accelerator community with a viability of ultrahigh gradient (TV/m)
acceleration for future HEP collider. The major challenge of channeling
acceleration is that ultimate acceleration gradients might require a high power
driver in the hard x-ray regime (~ 40 keV). This x-ray energy exceeds those for
x-rays as of today, although x-ray lasers can efficiently excite solid plasma
and accelerate particles inside a crystal channel. Moreover, only disposable
crystal accelerators are possible at such high externally excited fields which
would exceed the ionization thresholds destroying the atomic structure, so
acceleration will take place only in a short time before full dissociation of
the lattice. Carbon-based nanostructures have great potential with a wide range
of flexibility and superior physical strength, which can be applied to
channeling acceleration. This paper presents a beam-driven channeling
acceleration concept with CNTs and discusses feasible experiments with the
Advanced Superconducting Test Accelerator (ASTA) in Fermilab.
