论文摘要
我们报告了一个新型的共线激光光谱检测系统，该系统通过使用弯曲的表面镜，为荧光光子检测提供了近4π$实心角度。其他抛物线角过滤器提供被动式流浪光抑制，并且可以配置以匹配实验条件。镜面在光谱中的宽波长上具有出色的反射率，并且可以取代以进一步扩大波长的接受范围。该系统的实验是在两个共线激光光谱设置上进行的，包括使用NSCL的25/s的$^{36} $ CA对$^{36} $ CA进行的激光光谱研究。
We report on a novel detection system for collinear laser spectroscopy which provides an almost $4π$ solid angle for fluorescence photon detection by employing curved surface mirrors. Additional parabolic angular filters offer passive stray light suppression and can be configured to match the experimental conditions. The mirror surfaces have an excellent reflectivity over a broad band of wavelengths in the optical spectrum and can be substituted to expand the wavelength acceptance range even further. Experiments with this system were performed at two collinear laser spectroscopy setups, including the laser spectroscopic investigation of $^{36}$Ca using rates of 25/s at NSCL, MSU.
