Method of beam transverse profile measurement in accelerator by wire
scanner is wide spread in accelerator field. The wire scanner is used in
beam transfer lines of European Synchrotron Radiation Facility (ESRF) to
provide data for beam profiles, which is being used in emittance
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
horizontal 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 = 18 A) we get
the emittance value for the vertical plane. The value is 1.5·10-6 mrad.
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 the focus quad at (focus quad = 10.46 A) we
get the emittance value for the horizontal plane. The value is 2·10-7
mrad. And we find that the simulation gives good fitting with real
values.
