梯度法对HIRFL束流发射度的测量

Abstract

利用磁四极透镜和二次发射多丝剖面监测器测量了ＨＩＲＦＬ横向束流（￣（１２）Ｃ￣（６＋））发射度。测量中采用了多次测量和最小二乘法拟合的方法，给出了发射度及其测量误差的计算方法和测量结果。HIRFL beam￣(12)C￣(5+) emittance is measured by means of quadrupole and secondary emissionmulti-wire profile monitor.A series of measurements are performed and a weighted least squaresfit is used in the data processing.This paper will describe the method of emittance calculation andits error calculation.Some of the measurement results are also presented in the paper
