【摘要】 本文报道了利用多丝束流剖面仪测量从等时性回旋加速器中引出束流的轴向性能,包括束流的中心位置、相对于磁场中心平面的夹角及束流在轴向的发射度。同时也测量了束流引出区环形补偿线圈中的励磁电流变化对引出束流性能的影响。测量结果表明,环形线圈电流变化对束流轴向发射度的影响较大,而对束流中心在轴向几何位置的影响较小。更多还原

【Abstract】 The measurements of vertical behaviour of the beam extracted from AVF cyclotron with a SEM multiwire beam profile monitor are reported. The influence of circular trim coil current variation on vertical beam behaviour is also determined experimentally. The results -show that the variation of trim coil current has greater influence on the vertical beam emittance than. on the beam center displacement in the vertical direction.更多还原
