Consideration of laser-driven plasma-based electron/positron accelerators with a 2 TeV center-of-mass energy is presented, employing a multistaging scheme consisting of successive multi-GeV laser wakefield accelerators operated at the plasma density range of 10(15)-10(18) cm(-3) in the quasilinear regime. A total accelerator length is determined by an operating plasma density and a coupling distance allowed for both laser and beam focusing systems. We investigate beam dynamics and synchrotron radiation due to the betatron oscillation of the beam in laser-plasma acceleration, characterizing the beam qualities such as energy spread and transverse emittance. According to the criteria on the beam qualities for applications and available laser sources, the operating plasma density will be optimized. We note that in the low density operation the required wall-plug power for the laser driver will be much reduced in comparison with the high-density options.
