The Compact Energy Recovery Linac (cERL) is under construction at KEK for the future 3-GeV ERL project. During the past year, we have finished key devices, such as a 500-kV DC photocathode electron gun and superconducting (SC) cryomodules for the injector and for the main linac. We installed these devices into a shielding room of the cERL, and carried out high-voltage or high-power tests successfully. In the April of 2013, the 5-MeV injector of the cERL was completed. During April to June in 2013, we commissioned the cERL-injector successfully, and carried out beam tuning and studies. We will present the construction and commissioning of the cERL injector, together with the construction status of a return loop.

In order to demonstrate required accelerator technologies in the 3 GeV ERL light source, cERL, which is now under construction, is starting the commissioning of an injector part from the April of 2013. Along with the operation, the quantum beam obtained from cERL is providing to user experiments. In 2014-15, the construction of beamlines for advanced researches using x- and gamma-rays and terahertz (THz) beam will be starting. Due to an inverse Compton scattering (ICS) of laser pulses on relativistic electron bunches in a ring of the cERL, ultra-short x-ray is produced. The 100 fs x-ray beam from cERL, which is generated by the ICS using high-power and ultra-short laser pulses, is significantly benefit for researches in the field of ultrafast science. On the other hand, high-flux x- and gamma-rays, which is generated by the ICS using an optical build-up cavity and high-frequency laser pulses, is an ideal light source for x-ray imaging and nuclear resonance fluorescence. Furthermore, the coherent synchrotron radiation (CSR) from electronic bunch in cERL can be used as a novel light source for researches of physical properties, because it has high intensity in a THz region. In addition to the hard x-ray beamline, construction of the THz beamline is also being scheduled. At a poster, we will present the outline of the design of these two beamlines and expected applications.
