 note = {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 Free-Electron Laser (FEL) project
with a competitive funding. The purpose of this project is
to build a mid-infrared FEL based on the cERL, and to use
that FEL as a light source for creating the processing database required for industrial lasers. The FEL system is a single-pass FEL composed of two 3-m undulators and a
matching section between them. The FEL was constructed
from October 2019 to May 2020. The commissioning was
completed successfully, and the target power of the project
was almost achieved.},
