The Mark III IR FEL has been upgraded by the installation of a new thermionic microwave gun. The new gun yields a reduced emittance and allows operation at a higher repetition rate and an increased electron macropulse length. The RF system of the Mark III has also been phase-locked to the RF systemof the adjacent storage ring driver for the laboratory`s short-wavelength FEL sources, making possible two-color UV-IR pump probe experiments. In this paper, the design and performance of the new gun are presented and the implications of the improvements investigated.
