质子极化仪安装在串列加速器HI-13的R20管道上,离Q3D谱仪1.5m处,8月份用非极化质子束对本装置的对称性进行了检验。极化仪由装有气压为3×10~5Pa~4He的气体靶室、左右对称的二套双光阑系统和闪烁探测器组成。气体靶室可以升降,其窗为20μm厚的不锈钢膜,并用钖焊在靶室上。二套探测器系统与束流方向成±112°,具体尺寸见图1。电子学线路框图见图2。

The proton polarizer was mounted on the R20 tandem accelerator HI-13 at a distance of 1.5 m from the Q3D spectrometer. In August, the symmetry of the device was examined using a non-polarized proton beam. Polarimeter equipped with gas pressure of 3 × 10 ~ 5Pa ~ 4He gas target chamber, left and right symmetrical two sets of double aperture system and scintillation detector. Gas target chamber can be raised and lowered, the window is 20μm thick stainless steel membrane, and 钖 welded to the target chamber. Two sets of detector system and beam direction into ± 112 °, the specific size shown in Figure 1. Electronics circuit diagram shown in Figure 2.
