用UCN进行新引力实验的光谱仪
Spectrometer for new gravitational experiment with UCN
摘要：
本文介绍了一种新的中子弱等效原理检验装置。该装置是用于超冷中子的灵敏引力谱仪，允许精确地比较自由下落中子的动能增益与经由非静止装置（即量子调制器）转移到中子的能量量子${\hbar}Ω$。第一测试实验的结果指示允许测量等效因子$ { γ}$的收集率，其具有每天$5{\times}10^{-3}$的数量级的统计不确定性。发现了一些系统性影响，其中部分可以很容易地纠正。为了消除其他人，需要进行更详细的调查和分析。还讨论了改进该装置的可能性。
英文摘要：
We describe an experimental installation for a new test of the weak equivalence principle for neutron. The device is a sensitive gravitational spectrometer for ultra-cold neutrons allowing to precisely compare the gain in kinetic energy of free falling neutrons to quanta of energy ${\hbar}Ω$ transferred to the neutron via a non stationary device, i.e. a quantum modulator. The results of first test experiments indicate a collection rate allowing measurements of the factor of equivalence $ { γ}$ with a statistical uncertainty in the order of $5{\times}10^{-3}$ per day. A number of systematic effects were found, which partially can be easily corrected. For the elimination of others more detailed investigations and analysis are needed. Some possibilities to improve the device are also discussed.
