Beam emittance measurement for european synchrotron radiation facility

The wire scanner is used in beam transport lines of european synchrotron radiation facility (ESRF) to provide data for beam profiles, which is being used in emitance measurements. The beam energy in the first transport line is 200 MeV and the peak current is 25 mA. The purpose of the scanner is to provide horizonal and vertical beam profiles. This work will discuss the operation of the wire scanner, and the first results of the scanner in ESRF. By changing the value of focus quad at (de focus quad=18A) we get this value to emittance value for the vertical plane. The value is 1.5 x 10-6 m.rad. When we used this value to simulate our result we find that, the simulation gives good fitting with real values of vertical plane. Also by changing the value of de focus quad at (foucs quad = 10.46A) we get the emittance value for the horizontal plane. The vlaue is 2 x 10-7 mrad . And we find that, the simulation gives good fitting with real values
