Strongly amplified X-ray laser observed in the recent transient collisional excitation (TCE) experiments pumped by a single short pulse suggests that with the help of low level prepulse producing lowly ionized preplasma it is also possible to obtain high gain in the TCE scheme. The TCE Ne-like Ge 19.6nm X-ray laser pumped by low level prepulse were studid with our code series. Time evolution of plasma status shows that the position of peak gain drifts outward and the gain region is widened as time goes on, which is similar to the QSS scheme.
