  The electron energy of the HESR electron cooler shall be variable from 450 keV to 4.5 MeV. Furthermore, the design shall not exclude a further upgrade to 8 MeV. Operation of the HESR in a collider mode, which requires electron cooling of both protons and antiprotons traveling in opposite directions, is an interesting option. The status of the technical design of the HESR electron cooling system will be presented.

  The FEMTO source at the SLS (Swiss Light Source) employs laser/e-beam 'slicing' to produce sub-picosecond x-ray pulses for time resolved pump/probe experiments. The final design of the source, the status of construction and commissioning as well as the first experimental results will be presented.
