The emittance calculated with two different methods, one with thin-lens approximation and the other one without this approximation. The results are compared and analyzed. To analyze the measurement error, quadrupole calibration is need. Two aspects about quadrupole analysis are made. The first one is thin-lens approximation error and the second one is quadrupole¿s converged or diverged ability in reality. PB - JACoW Publishing CP - Geneva, Switzerland ER -
