Experimental and theoretical studies of the isochronous synchrotron radiation ring, so far, suggest nonlinear effect resulted from higher order dispersion and chromaticity declines the "complete" isochronous system [1]. In addition, we have recently found that path-length deviation originated from the betatron motion is a much seriouse obstacle to preserve the bunch length [2]. However, It has been found out that a careful lattice design for the path-length cancellation seems to be very promissing, at least for a wavelength region of THz. Tolerance of the path length along a turn of the ring may be within our reach. A concept to preserve bunch form-factor (or very short bunch) by using quasi-dispersion-free arcs having proper betatron phase advances in order to produce coherent THz radiation from every bending section. Furthermore, its extension toward prebunched-FEL and SASE-FEL will be also discussed.
