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.

Optics design and simulation of the beam dynamics are under consideration for the beam commissioning of the compact ERL circular loop scheduled for December. The beam optics from the electron source to dump is optimized by start-to-end simulation to include the effects of space charge and CSR wake, in which the simulation code of 'General Particle Tracer, GPT' and 'elegant' are utilized in the injector and circulator, respectively. The beam loss caused by field emission of the main superconductive accelerator is also evaluated toward the beam commissioning. The compact ERL is planned to be utilized as a user experiment machine in the near future. The optics is also designed for laser-Compton X-ray source and the bunch compression simulation is performed for CSR source in the THz region. In this presentation, we introduced the current status of the optics design.
