  High luminosity THz and X-ray radiation are vital for many branches of science and industry (for example biochemistry and material science) and to achieve it a high electron bunch current is needed. Another requirement to such radiators is high wall plug efficiency. The efficiency is usually very low and the electron beam energy recovery is the most attractive way to improve it. This is normally done using SCRF ERL systems but the bunch current limitations for these systems are more dramatic when compared with a conventional LINACs. Increase of the bunch current in conventional ERLs above some threshold value (normally around 100 mA) leads to beam instabilities development and beam transportation termination. This naturally limits the instruments' luminosity. Here we suggest and discuss the novel concept and specific designs which can enable a SCRF ERL system capable of generating picosecond electron bunches with up to 1A current. The aim of the project is to demonstrate the operation of dual axis asymmetric ERL and its application in research and industry. A preliminary market research of such devices has been recently conducted and results will be also presented.
