Description

HZDR is planning a successor facility for the ELBE radiation source: the Dresden Advanced Light Infrastructure DALI. DALI will include a positron source, an MeV UED instrument, an optical klystron mid-IR source for 3 to 30 THz, requiring bunch lengths of 10 to 20 wavelengths, and a superradiant THz source for frequencies up to 3 THz. The bunch length for the superradiant source needs to be shorter than the radiation wavelength 100 µm, which is expected to require magnetic linearization.
Several options for the envisaged nonlinear bunch compressors will be discussed.
