As a fundamental theorem in free-electron lasers, the Madey theorem reveals the relationship between the spontaneous radiation and the stimulated radiation. In this paper, this problem is studied for transition-radiation free-electron lasers. The results show that there is a formula corresponding to the first part of Madey's theorem; the former is more complicated while the second part remains the same. The results obtained are used to simplify the small-signal gain calculation.
