Description
The Dresden Advanced Light Infrastructure (DALI), a 50 MeV superconducting linac currently under development at Helmholtz-Zentrum Dresden-Rossendorf, aims to deliver from one of its sources high-brightness, few cycle THz radiation through superradiant emission in a dedicated undulator. Efficient superradiant generation requires electron bunches with a form factor matched to the desired wavelengths between 0.1 and 3 THz. Achieving such short bunches at the design charge of 1 nC, however, is constrained by space charge forces and coherent synchrotron radiation in the magnetic chicane used for compression. This work discusses the design of the superradiant THz beamline with emphasis on the attainable compression performance and the resulting impact on the THz output. Quantitative tradeoffs between compression strength, bunch quality, and expected radiation yield are discussed to guide the optimization of the DALI THz source.
