Abstract

The production of ultralow emittance electron beams in single-bunch-mode operation of accelerator test facility was reported. Gamma rays produced by Compton scattering were detected by a scintillation detector. The horizontal beam size was measured using a screen monitor in a high dispersion region in the extraction line. At the zero intensity limit, the horizontal emittance and vertical emittance were 1.1× 10-9rad m and less than 1.1× 10-11 rad m. At high intensity, strong effects of intrabeam scattering were observed.
