Abstract: This paper describes design of a compact infrared FEL for scientific applications. The driving rf accelerator consists of two accelerating sections providing the electron beam with the energy up to 20 MeV. Each accelerating section is powered by compact S-band klystron (frequency 2450MHz, peak power 10 MW, pulse duration 10 microseconds, average power 10 kW). Average power in the electron beam is up to 2 kW. The injector of the driving accelerator consists of a conventional thermionic gun and subharmonic bunchers providing the value of the peak current up to 30 A with programmable pulse format. The undulator is a hybrid planar one with $Nd^2Fe^{14}B$ permanent magnets. Operating wavelength range of the FEL is 3-100 microns, and average output radiation power is about of a few watts.
