The com­pact En­ergy Re­cov­ery Linac (cERL) has been in op­er­a­tion at KEK since 2013 to demon­strate ERL per­for­mance and de­velop ERL tech­nol­ogy. Re­cently KEK has launched an in­frared FEL pro­ject with a com­pet­i­tive fund­ing. The pur­pose of this pro­ject is to build a mid-in­frared FEL at the cERL, and to use that FEL as a light source for con­struc­tion of the pro­cess­ing data­base re­quired for in­dus­trial lasers. The FEL sys­tem is com­posed of two 3-m un­du­la­tors and a match­ing sec­tion be­tween them, and gen­er­ates light with a max­i­mum pulse en­ergy of 0.1 mi­cro-J at the wave­length of 20 mi­crons with an 81.25 MHz rep­e­ti­tion rate. The FEL is also ex­pected to be­come a proof-of-con­cept ma­chine for ERL base FELs for fu­ture EUV lith­o­g­ra­phy.
