Ultra-bright electron beams can be produced by near-threshold photo ionization of a laser-cooled atom cloud inside a magneto-optical trap. Such laser-cooled sources have orders of magnitude lower emittance compared to photo-emission sources because of their low initial temperature. The application we have in mind is single-shot ultrafast electron diffraction, but these sources are also interesting as injectors for X-FELs in the low-charge, low-emittance regime. At Eindhoven University of Technology a laser-cooled electron source has been constructed and electron pulses have been produced using both nanosecond and sub-picosecond photo-ionization laser pulses. In both cases thermal emittances have been measured corresponding to an effective source temperature of
