在储存环的束流传输系统中 ,斜四极场和纵向螺线管场是引起束流线性耦合的主要原因 .由于这种耦合 ,使得束流的幅度和发射度发生交换 ,引起束流横向包络的增大 ,严重的将造成束流损失 .从Betatron运动方程出发研究了斜四极场和螺线管场存在时束流的幅度耦合效应 ,分析了斜四极场存在时束流发射度的变化 . In the storage ring beam transmission system, the oblique quadrupole field and the longitudinal solenoid field are the main reasons for the linear coupling of the beam, because of this coupling, the amplitude and the emittance of the beam are exchanged, causing the lateral The enlarging of the envelope will seriously cause the loss of the beam.Starting from the Betatron equation of motion, the amplitude coupling effect of the beam in the presence of oblique quadrupole and solenoid fields is analyzed, and the beam emission in the presence of oblique quadrupole Degree of change.
