【 摘 要 】

Compactness of linear accelerator is significant factor in achieving short construction times, low infrastructure and operation costs, and is considered as one of a key parameters for next accelerator generation particularly for high-energy physics. Operation of XFEL and design of LCLS-II accelerators as well as tests of Cornell injector and main cryomodule show the possible limitations on present technologies related to the RF power operation inside the modules. The next development steps could be either further increase of Q 0 factor of the cavities or other cooling schemes. In the present paper, modification of the helium bath cooling scheme is proposed. This will allow increasing the RF power by factor two or more. Its application for TESLA-style cryomodule is considered.
