Stable operation of a fully energy-recovered 1-mA-class electron beam at a compact energy-recovery linac

Hiroshi Sakai, Dai Arakawa, T. Furuya, K. Haga et autres

A compact energy-recovery linac (cERL) has been under development at KEK to drive key accelerator technologies, demonstrate energy recovery under various conditions, and support beam applications. cERL began beam operations in 2013 to create stable, low-emittance, energy-recovered beams. The project focused on …

Stable beam operation of approximately 1 mA beam under highly efficient energy recovery conditions at compact energy-recovery linac

Hiroshi Sakai, Dai Arakawa, T. Furuya, K. Haga et autres

A compact energy-recovery linac (cERL) has been un-der construction at KEK since 2009 to develop key technologies for the energy-recovery linac. The cERL began operating in 2013 to create a high-current beam with a low-emittance beam with stable continuous wave (CW) superconducting …

Reconstruction and beam-transport study of the cERL dump line for high-power IR-FEL operation

Norio Nakamura, Yasunori Tanimoto, Nao Higashi, Kentaro Harada et autres

Abstract Infrared (IR) SASE-FEL emission was successfully generated for macro pulses of about 1 μs with the maximum repetition rate of 5 Hz at the cERL. In the future, high-power FEL operation will be planned to increase electron bunches drastically with energy …

Construction and commissioning of mid-infrared self-amplified spontaneous emission free-electron laser at compact energy recovery linac

Y. Honda, Masahiro Adachi, Shu Eguchi, Masafumi Fukuda et autres

The mid-infrared range is an important spectrum range where materials exhibit a characteristic response corresponding to their molecular structure. A free-electron laser (FEL) is a promising candidate for a high-power light source with wavelength tunability to investigate the nonlinear response of materials. …
