The Shanghai Laser Electron Gamma Source(SLEGS, located in BL03SSID) beamline at the Shanghai Synchrotron Radiation Facility(SSRF) is a Laser Compton Scattering(LCS) gamma source used for the investigation of nuclear structure, which is in extensive demand in fields such as nuclear astrophysics, nuclear cluster structure, polarization physics, and nuclear energy. The beamline is based on the inverse Compton scattering of 10640 nm photons on 3.5 GeV electrons and a gamma source with variable energy by changing the scattering angle from 20° to 160°. γ rays of 0.25-21.1 MeV can be extracted by the scheme consisting of the interaction chamber, coarse collimator, fine collimator, and attenuator. The maximum photon flux for 180° is approximately 10~7 photons/s at the target at 21.7 MeV, with a 3-mm-diameter beam. The beamline was equipped with four types of spectrometers for experiments in( γ,γ'),( γ,n),( γ,p), and( γ,α). At present, Nuclear Resonance Fluorescence(NRF) spectrometry, Flat-Efficiency neutron Detector(FED) spectrometry, neutron Time-Of-Flight(TOF) spectrometry, and Light-Charged Particle(LCP) spectrometry methods have been developed.

上斜肌麻痹是临床常见的一种垂直旋转性斜视类型,分型较多,不论哪种类型的上斜肌麻痹,Bielschowsky试验在其诊断中均有重要作用,往往被认为是诊断和鉴别诊断的重要标准。但Bielschowsky试验对于诊断上斜肌麻痹的敏感度和特异度并非100%,这是因为Bielschowsky试验的产生机制并非单纯的眼外肌运动不平衡,还涉及前庭和中枢的反射通路,因而累及到相应部位的病变,都有可能产生Bielschowsky试验阳性的结果。而一些前庭和中枢的病变亦有可能引发斜视,所以Bielschowsky试验阳性和上斜肌麻痹并非一一对应关系,正确解读Bielschowsky试验在上斜肌麻痹中的作用对于临床工作的开展与相应疾病的治疗具有重要意义。
