Superconducting RF cavities are broadly employed for charged particle accelerators nowadays and usually cooled down to 2K by liquid helium to become superconducting. A cryoplant with trained personnel is required to provide liquid helium for cooling which makes usage of SRF technology not-user friendly for industry. A new approach is possible which substitute liquid helium cooling by conduction cooling. In this case SRF cavity is connected by thermal links to a commercially available cryo-cooler. COMSOL Multiphysics^® simulation software was used to find stable operation regimes for such system. Required level of thermal resistance was found in order to get a stable operation of the cavity which was experimentally confirmed.
