  It has recently been pointed out that arbitrary center-of-mass energies may
be obtained for particle collisions near the horizon of an extremal Kerr black
hole. We investigate this mechanism in cylindrical topology. In particular we
consider the center-of-mass energies of a cylindrical black hole with an
extremal rotation and charge parameter. The geodesics are first derived with a
rotating charged cylindrical black hole producing the background gravitational
field. Finally the center-of-mass is determined for this background and its
extremal limit is taken.
