	Transverse-to-longitudinal phase space exchange techniques have open new possibilities toward shaping the temporal distribution of electron bunches. Recently, the combination of such exchange methods with structured, e.g. field-emission, cathodes was suggested as the backbone of compact coherent short-wavelength sources [W. S. Graves, {\em et al.}, ArXiv:1202.0318 (2012)]. In this paper, we present the design and numerical investigation of a proof-of-principle experiment to produce coherent optical transition radiation using a ~4-MeV electron bunch. The optically-modulated bunch is produced from a structured cathode combined with a transverse-to-longitudinal phase space exchanger. The current status of the experiment are also summarized.

Transverse-to-longitudinal phase space exchange techniques have open new possibilities toward shaping the temporal distribution of electron bunches. Recently, the combination of such exchange methods with structured, e.g. field-emission, cathodes was suggested as the backbone of compact coherent short-wavelength sources [W. S. Graves, {\em et al.}, ArXiv:1202.0318 (2012)]. In this paper, we present the design and numerical investigation of a proof-of-principle experiment to produce coherent optical transition radiation using a ~4-MeV electron bunch. The optically-modulated bunch is produced from a structured cathode combined with a transverse-to-longitudinal phase space exchanger. The current status of the experiment are also summarized.
