The first project of the four turn ERL for Novosibirsk FELs (NovoFEL) was proposed at FEL'90 Conference. Later the project was modified, but the base lines kept: a four turn normal conductance linac with energy recovery, low RF cavities (180 MHz), grid controlled DC gun (Q~1 nC, tau=1 nsec, f rep = 10 kHz-50 MHz). The ERL can operate in the three modes, providing an electron beam for the three different FELs (from 300 µm up to 5 µm). Construction and commissioning four track ERL was divided on three stage: the first stage NovoFEL working in spectral range (90-240) µm, based on one track energy recovery linac (ERL) with energy 12 MeV and current 30 mA, was commissioned in 2003. The second stage of NovoFEL working in spectral range (35-80) µm, based on two track energy recovery linac with energy 22 MeV and current 7 mA, was commissioned in 2009. The third stage of NovoFEL working in spectral range (8-15) µm, based on four track energy recovery linac with energy 42 MeV and current 5 mA was commissioned in 2015.
