N1 - Funding Information:
We are grateful to G. N. Kulipanov, V. A. Soifer, and N. A. Vinokurov for sustaining this work and useful discussions. We would like to especially note the great contribution by V. S. Cherkassky, Yu. Yu. Choporova, and A. K. Nikitin in our previous investigations of vortex beams and plasmons, the results of which enabled us to interpret the findings of this work. Successful implementation of this study would have been impossible without the use of high-power terahertz radiation, and we are grateful to Ya. V. Getmanov, Ya. I. Gorbachev, D. A. Skorokhod, and O. A. Shevchenko, who ensured in our experiments the reliable operation of the Novosibirsk Free Electron Laser, which is a part of the Shared Research Facility Siberian Synchrotron and Terahertz Radiation Center." This work was funded by the Russian Science Foundation, grant 19-12-00103.

N2 - Surface plasmon polaritons (SPPs) carrying an orbital angular momentum were first obtained at a cylindrical brass-ZnS-air interface due to the diffraction of perfect vortex beams at the front end of a cylinder. The beams with a wavelength of 141 µm resulted from the transformation of a Gaussian beam of a free electron laser using a binary axicon and a lens. The propagation of rotating plasmons along an axisymmetric surface over a distance of 70 mm and their diffraction at the rear end of a cylindrical transmission line with conservation of the topological charge of the diffracted free wave were demonstrated.
