Measurement and Correction of Chromaticity in Hefei Light Source

介绍了合肥 80 0MeV电子储存环的色品测量与校正。采用改变二极铁电流方法测量了自然色品和采用改变RF频率方法测量了校正色品 ,并对这 2种测量方法进行了理论分析和公式推导 ,还给出了自然色品。

The measurement and correction of chromaticity for Hefei light source were introduced. The natural chromaticity was obtained by detecting the variation of the betatron tune with the main dipole field strength. The correction chromaticity was obtained by detecting the variation of the betatron tune with the RF frequency. The theoretical analysis and formula for the two methods were given. The measuring results of chromaticity were presented.
