At the Free Electron Laser (FEL) Laboratory of Duke University, there is an S-band linac based Mark III FEL facility which can supply coherent FEL photon beam in the infrared wavelength range. To supply high quality electron beams and to have excellent pulse structure, we installed a new S-band RF GUN with the LaB6 cathode for the Mark III FEL facility in 2005. Since maximum repetition rates of macropulse and micropulse are 15 Hz and 2856 MHz, respectively, our new RF GUN can generate 17142 bunches within a 6 us long bunch train, and maximum 257130 bunches within one second. In this paper, we describe recent commissioning experiences of our newly installed S-band RF GUN and Linac for the Mark III FEL facility.
