SlimCS is the conceptual design of a compact fusion DEMO plant assuming technologies foreseeable in 2020s-2030s. Considering continuity of blanket technology from the Japanese proposal on ITER-TBM, the prime option of blanket is water-cooled solid breeder with Li$$_{2}$$TiO$$_{3}$$ and Be (or Be$$_{12}$$Ti). A reduced-activation ferritic-martensitic steel and pressurized water are chosen as the structural material and coolant, respectively. Toroidal coils produce the peak magnetic field above 16 T using the RHQT processed Nb$$_{3}$$Al conductors. The structure and materials of the conducting shell and divertor are also presented.
