Abstract :
In 1997, Huang and Ruth proposed a compact laser-electron storage ring (LESR) for electron beam cooling or X-ray generation. Because the laser-wire monitor in the ATF storage ring has worked well and demonstrated the achievement of the worldʹs smallest transverse emittance for a circulating electron beam, we have started the design of a small storage ring with about 10 m circumference and the development of basic technologies for the LESR. In this paper, we describe the design and experimental results of pulse stacking in a 42-cm long optical cavity. Since our primary purpose is to demonstrate the proof-of-principle of the LESR, we will discuss the future experimental plan at the KEK–ATF for the generation of high average-brilliance gamma-rays.
