Abstract
During the BEPC-II (Beijing Electron and Positron Collider-II) linac upgrade in the summer of 2012, five wire scanners have been installed in the common transport line which connects the linac and the beam transport lines for electrons and positrons. Up to now, four of the five wire scanners could be routinely used for beam size measurement, which makes a fast emittance measurement possible. In this paper, we will show the primary results of BEPC-II linac emittance measurement using the multiple wire scanner method. The least squares method will be used for data analysis.
