MuSIC@Indiana: an effective tool for accurate measurement of fusion with low-intensity radioactive beams
摘要:
介绍了多采样电离室MuSIC@Indiana的设计、结构和特性。该探测器提供了有效和准确的测量近势垒能量的聚变截面。在E $_{lab}$ = 50-60 MeV下,检测器对$^{17,18}$ O、$^{19}$ F、$^{23}$ Na、$^{24,26}$ Mg、$^{27}$ Al和$^{28}$ Si的低强度束的响应。MuSIC@Indiana是通过使用CH $_{4}$气体测量11 $<$ E $_{cm}$ $<$ 20 MeV的$^{18}$ O+ $^{12}$ C聚变激发函数而委托的。一个简单、有效的分析清楚地区分了质子捕获和两体散射事件与碳上的聚变。使用MuSIC@Indiana,实现了对单个入射光束能量的激发函数上的15个点的测量。所得的激发函数与文献数据吻合较好
英文摘要:
The design, construction, and characterization of the Multi-Sampling Ionization Chamber, MuSIC@Indiana, are described. This detector provides efficient and accurate measurement of the fusion cross-section at near-barrier energies. The response of the detector to low-intensity beams of $^{17,18}$O, $^{19}$F, $^{23}$Na, $^{24,26}$Mg, $^{27}$Al, and $^{28}$Si at E$_{lab}$ = 50-60 MeV was examined. MuSIC@Indiana was commissioned by measuring the $^{18}$O+$^{12}$C fusion excitation function for 11 $<$ E$_{cm}$ $<$ 20 MeV using CH$_{4}$ gas. A simple, effective analysis cleanly distinguishes proton capture and two-body scattering events from fusion on carbon. With MuSIC@Indiana, measurement of 15 points on the excitation function for a single incident beam energy is achieved. The resulting excitation function is shown to be in good agreement with literature data
