【摘要】 在JLab的A大厅上的小角度GDH实验中,采用了Fumili拟合方法对位于高分辨谱仪上的量能器进行刻度．因为实验过程中硬件条件的变化以及大量的运动学数据的存在,对该实验数据分批进行了刻度．刻度结果表明,此刻度修正是合适的．在散射电子动量为1GeV的时候,量能器对该粒子的分辨率为0．06GeV．更多还原

【Abstract】 The Fumili minimization method was used in the calibration for the calorimeter counter on HRS at Hall-A in Jefferson Jlab(JLab)for the data of small angle GDH experiment.Due to a large set of kinematics and changes in hardware settings,different calibrations were needed for the calorimeter detector.The resolution of the calorimeter for the scattering electron was about 0,06GeV when its momentum was at 1.0GeV.更多还原
