The Carbon Nanotube Accelerator
(CNT) has central protons inside
the nanotube, as well as exterior
carbon and gold ions (for coating).

Then, the AC electric field of
7x10^17 W/cm2 is applied to the
nanotube. Protons are expelled
viollently along the parallel direction.

When the electric field of 1x10^22 W/cm2
is used, it has relativistic electrons and
protons, as is shown in Comp. Physics
Communications in Elsevier Publisher (2019).
