In order for sources of coherent high brightness and intensity THz and X-Rayradiation to be accepted by university or industrial R&D laboratories, trulycompact, high current and efficient particle accelerators are required. Thedemand for compactness and efficiency can be satisfied by superconducting RFenergy recovery linear accelerators (SRF ERL) allowing effectively minimisingthe footprint and maximising the efficiency of the system. However such set-upsare affected by regenerative beam-break up (BBU) instabilities which limit thebeam current and may terminate the beam transport as well as energyrecuperation. In this paper we suggest and discuss a SRF ERL with asymmetricconfiguration of resonantly coupled accelerating and decelerating cavities. Inthis type of SRF ERL an electron bunch is passing through accelerating anddecelerating cavities once and, as we show in this case, the regenerative BBUinstability can be minimised allowing high currents to be achieved. We studythe BBU start current in such an asymmetric ERL via analytical and numericalmodels and discuss the properties of such a system.
