Focal Plane Polarimeter Trigger (Physics)

将在麻省理工学院/贝茨直线加速器设施建造一个焦平面偏振仪，供威廉和玛丽学院中能核物理组使用。具体来说，该旋光计将用于“100光谱仪(OHIPS)”，用于测量电子散射后的反冲质子极化。首次开放与干扰效应对应的反应矩阵元素进行研究。第一次测量将是对质子磁结构函数的新确定。这将提供对确定中子电荷形状因数的反应机制的测试。这个新设施还计划进行许多其他实验。

A focal plane polarimeter will be constructed for use by the William & Mary College Intermediate Energy Nuclear Physics Group at the MIT/Bates linear accelerator facility. Specifically, the polarimeter will be used in the "100 Spectrometer (OHIPS)" for measurement of recoil proton polarization following electron scattering. Reaction matrix elements corresponding to interference effects will be opened to study for the first time. The first measurement will be a new determination of the magnetic structure function of the proton. This will provide a test of the reaction mechanism through which the neutron charge form factor will be determined. Many other experiments are planned for this new facility.
