چکیده
In order to develop the photo cathode gun for the Compact ERL (cERL), which is a test accelerator to establish accelerator technologies for GeV-class synchrotron light source based on ERL (Energy Recovery Linac), Gun Test Facility is constructing in KEK, AR south experimental hall. The Gun Test Facility consists of a 500 kV gun construction area, a laser system area and a gun test beamline with beam diagnostic system. Design of the gun chamber, the insulators, and the preparation chambers for the 500 kV gun were finished. Vacuum test of the gun system started at April 2010. Development of 1.3 GHz fiber laser system for 1 mA beam commissioning is almost reach the target. To evaluate performance of the DC guns, the gun test beamline is developing in the beamline area. From April 2010, beam running in the gun test beamline started using NPES3 200 kV DC photo cathode gun.

Recent Progress in the Energy Recovery Linac Project in Japan
Future synchrotron light source using a 5-GeV energy recovery linac (ERL) is under proposal by our Japanese collaboration team, and we are conducting R&D efforts for that. We are developing high-brightness DC photocathode guns, two types of cryomodules for both injector and main superconducting (SC) linacs, and 1.3 GHz high CW-power rf sources. We are also constructing the Compact ERL (cERL) fo...

Cornell University is planning to build an Energy Recovery Linac (ERL) X-ray facility. For an ERL, it is well known that the x-ray beam brightness for the users is mainly determined by the initial electron beam emittance provided by the injector To address technical challenges of producing very low emittance beams at high average current as required for an ERL, Cornell University has proposed a...

We are currently working on a compac...
متن کاملSimulations of Xfelo for the Kek Erl
Following the recent development of high-brightness electron guns and high-reflectivity X-ray crystal optics, an FEL oscillator operated in a hard X-ray wavelength region (XFELO) has been considered as a possible extension of the 3-GeV ERL light source proposed at KEK. In order to deliver a 6-GeV electron beam to the XFELO, the ERL is operated at the energy-doubling mode with a low average curr...

The HZB (previously BESSY) was the first institution in Germany to build and operate a dedicated synchrotron light source (BESSY I). About 10 years ago BESSY II, a third generation synchrotron light source, was commissioned and is very successfully running since that time. Due to its expertise in development and operation of accelerator facilities HZB is ideally suited to realize new accelerato...
