Coherent electron cooling* using a plasma-cascade amplifier (PCA)** can provide significantly faster cooling of hadrons than the conventional microwave stochastic cooling due to a wide bandwidth of a pickup, a kicker, and an amplifier. The PCA creates unstable plasma oscillations by modulating the plasma frequency by varying the transverse beam size along the beam line. An alternative approach to the amplifier studied in this work is to modulate the plasma frequency by a sequence of wiggler magnets separated by weak chicanes. We present a new derivation of the amplifier spectral gain function following the initial analysis presented in ***. Numerical simulations of the gain function were also done using electron beam parameters projected for the Electron Ion Collider. The numerical results consistently show higher gains than those obtained using the analytical gain function.
