We construct a new aperiodic symplectic plug and hence new smooth counterexamples to
the Hamiltonian Seifert conjecture in ℝ2n
for n ≥ 3. In other words, we describe an alternative procedure, to those of V.L. Ginzburg
[Gi1, Gi2] and M. Herman [Her], for producing smooth Hamiltonian flows, on symplectic manifolds of
dimension at least six, which have compact regular level sets that contain no periodic orbits.
The plug described here is a modification of those built by Ginzburg. In particular, we use
a different "trap" which makes the necessary embeddings of this plug much easier to construct.
