摘要
First lasing at 3mm wavelength was achieved on December 4, 1996 in our FEL employing a modified EN-Tandem electrostatic accelerator as the source of energetic free electrons. A Pierce-type electron gun capable of providing a 2A beam was installed at the entrance to the accelerator and operated at 1.4A level, while the wiggler (lambda(w)=4.4cm, N-w=26) was located in the center of the accelerator, inside the positive HV terminal. The electron gun voltage was V-gun=-43kV and the terminal operating voltage V-term=1.4MV. The resonator, consisting of two parallel curved plates waveguide terminated by wave splitters at its both ends, was mounted inside the wiggler. Radiation pulses at 100.5 GHz of 2 mu sec duration and 1200W of power were obtained at intervals of 15 sec.
