During the BEPC-II linac upgrade, five wire scanners have been installed in the common transport line, which makes a fast emittance measurement possible. In this paper, we will show the primary results of BEPC-II linac emittance measurement using multi-wire scanner method. The least squares method will be used for data analysis. A comparison of the results with the ones obtained by quad scan method will also be given.

Wire scanners are diagnostic devices to measure the beam profile. Resent years, BEPCII adopts wire scanner measurement system for accurate beam size and emittance measurements. Beam emittance measurements can be performed with no adverse impact on beam and no interruption to normal machine operation. The BEPCII wire scanner system includes sets of four scanners in linac by which the linac output emittance is determined. In order to make the measurement procedure automated and easily accessible to all operators, wire scanner measurement software is developed. The software can obtain real-time signal data from the Experimental Physics and Industrial Control System(EPICS) and emittance calculation, phase chart and optics envelope display will be done. In this paper we describe the construction, performance and uses of BEPCII wire scanners measurement system and software.
