摘要：

Utilizing electron beams delivered by the new S-DALINAC with energies of 32.8 and 38.4 MeV, the pulse structure, charge per pulse and energy resolution were studied and found to meet or almost reach the requirements needed. Despite the low intensity of this FEL experiment, spectra of spontaneous emission could be recorded for the first and third harmonic. An accumulation of intensity up to twelve times compared to a single photon pulse could clearly be identified as at least twelve round trips within the cavity. A length region with distinct amplification of the spontaneous emission intensity could be established unequivocally.
