Alternating pulses current - chronopotentiometric stripping analysis (APC-CPSA) is a new method as a variant of chronopotentiometric stripping analysis (CPSA). During the stripping step an alternating pulse current with a high frequency in a square wave mode is imposed on the electrode system. Thus, tau and sensitivity of APC-CPSA is increased a lot. The tau, E similar to t equation and its reciprocal derivative equation for APC-CPSA are derived and verified by the experimental results.

Tibet serves as an important ecological security barrier for China. It has the largest national nature reserves in China, spanning372,000 km2and accounting for 30.94%of the land. Although the national nature reserve has provided ecological benefits, it has also resulted in serious conflicts between nature conservation and human development. Especially in the modernization period since the 21st century, Tibet has played an unprecedented important role in balancing protection and development. In this study, Selincuo, a key region explored during the Second Tibetan Plateau Scientific Expedition, was selected as a case study for discussion.

Real-time monitoring of the 14-MeV D-T fusion neutron yield is urgently required for the triton burnup study on the Experimental Advanced Superconducting Tokamak (EAST). In this study, we developed an optimal design of a fast-neutron detector based on the scintillating fiber (Sci-Fi) to provide D-T neutron yield through Geant4simulation. The effect on the detection performance is concerned when changing the number of the Sci-Fis embedded in the probe head, minimum distance between the fibers, length of the fibers, or substrate material of the probe head. The maximum number of scintillation photons generated by the n/γ source particles and output by the light guide within an event (event:the entire simulation process for one source particle) was used to quantify the n/γ resolution of the detector as the main basis. And the intrinsic detection efficiency was used as another evaluation criterion. The results demonstrate that the optimal design scheme is to use a 5 cm probe head whose substrate material is pure aluminum, in which 463 Sci-Fis with the same length of 5 cm are embedded, and the minimum distance between the centers of the two fibers is 2 mm. The optimized detector exhibits clear directionality in the simulation, which is in line with the expectation and experimental data provided in the literature. This study presents the variation trends of the performance of the SciFi detector when its main parameters change, which is beneficial for the targeted design and optimization of the Sci-Fi detector used in a specific radiation environment.
