TRIUMF宇称实验中光束偏振剖面的监测
A Monitor of Beam Polarization Profiles for the TRIUMF Parity Experiment
摘要:
TRIUMF实验E497是在pp散射中的宇称违反的研究,在该能量下,分析能力中的主导项预计将消失,从而测量弱相互作用风味守恒项的独特组合。希望在统计误差和系统误差方面都达到2 × 10 ^-8的灵敏度水平。主要的系统误差取决于横向偏振分量,并且至少取决于横向偏振的一阶矩。描述了一种新型的偏振仪,它测量偏振的两个横向分量作为位置的函数的轮廓。
英文摘要:
TRIUMF experiment E497 is a study of parity violation in pp scattering at an energy where the leading term in the analyzing power is expected to vanish, thus measuring a unique combination of weak-interaction flavour conserving terms. It is desired to reach a level of sensitivity of 2x10^-8 in both statistical and systematic errors. The leading systematic errors depend on transverse polarization components and, at least, the first moment of transverse polarization. A novel polarimeter that measures profiles of both transverse components of polarization as a function of position is described.
