To study ultrafast processes at the sub-picosec-ond level, novel methods based on coherent harmonic generation technologies have been proposed to generate ultrashort radiation pulses in existing ring-based light sources. Using the High Energy Photon Source as an example, we numerically test the feasibility of imple-menting one coherent harmonic generation technology, i.e., the echo-enabled harmonic generation (EEHG) scheme, in a diffraction-limited storage ring (DLSR). Two different EEHG element layouts are considered, and the effect of the EEHG process on the electron beam quality is also ana-lyzed. Studies suggest that soft X-ray pulses, with pulse lengths of a few femtoseconds and peak powers of up to 1 MW, can be generated by using the EEHG scheme, while causing little perturbation to the regular operation of a DLSR.
