转换电子能谱是研究原子核结构的有用工具,但由于重核能级密度高而产生的复杂光谱,使得从单核测量中提取最有用的信息变得困难。这项工作报告了将与各种锗探测器阵列同时使用的迷你橙色光谱仪ICOBLE改造成改进的FINTERNACTION EPOLE BALL(FIRBLE)光谱仪,以改进E0跃迁和转换电子系数的测量。采用了FreeCAD、COMSOL和Geant4模拟相结合的方法,对光谱仪中使用的磁铁滤光片的几何结构进行了优化,以显著提高目标能量范围为200keV-1 MeV的电子收集效率。六个橙色的迷你硅(锂)探测器阵列将被六个新的、更厚的硅(锂)探测器取代。实验测试表明,对于单磁滤光片和探测器对,在207Bi中,482keV K电子线的绝对效率从2.8%提高到5.3%。
Conversion electron spectroscopy is a valuable tool in nuclear structure studies, but the complex spectra resulting from the high density of levels in the spectra of heavy nuclei make it difficult to extract the most beneficial information from singles measurements. This work reports on the transformation of ICEBall, which was a mini-orange spectrometer that was used in coincidence with various Germanium detector arrays, to the improved fInternal conveRsion Electron Ball (fIREBall) spectrometer for the improved measurements of E0 transitions and conversion electron coefficients. A combination of FreeCAD, COMSOL, and Geant4 simulations were implemented to optimize the geometries for the magnet filters used in the spectrometer to significantly improve the efficiency of electron collection in the energy range of interest 200 keV-1 MeV. The array of six mini-orange Si(Li) detectors are to be replaced with six new, thicker Si(Li) detectors. Experimental tests reported here show a peak improvement in absolute efficiency from 2.8% to 5.3% for the 482 keV K electron line in207Bi for a single magnet filter and detector pair.
