Description

Beam commissioning of the recirculation loop of Compact ERL has been underway at KEK site since December 2013. The injection beam has been successfully accelerated up to full energy of 20 MeV and transported to the movable Faraday cup, located in the area just before where it merges with the injection beam. There was no significant beam loss thanks to the orbit tuning and optics matching. The orbit tuning of the deceleration beam (second pass in the main linac) is performed with reference to the BPM signal at the burst operation rather than on the normal screen monitor. The electron beam was successfully decelerated near the injection energy and was led to the main dump in a period of a few weeks. To minimize the dump electron energy, the orbit length of the recirculation loop is controlled with making a bump at the top of the second arc section. Comparing the input power with the reflection power of the main linac, we confirmed that the energy recovery was succeeded. In this paper, we also report the results of the recent beam commissioning, including the measurement results of linear optics and transverse emittance. (author)
