Coupler is proposed for superconducting QWR cavities being under consideration now as option for planned Nuclotron-based Ion Collider fAcility (NICA) injector upgrade. The goal was to develop power coupler operating at 162 MHz and feeding SC cavity with about 20 kW RF power. It provides Qext tuning range (1.5-3)E5 by inner conductor movement. Conservative design with two identical disk ceramic windows was chosen. Electrodynamic, thermal and mechanical simulations were carried out.
