Novel HPGe-BGO pair spectrometer enhances detecting high-energy γ -rays, suggesting improved applications.
We report on a novel design for a HPGe-BGO pair spectrometer with the aim to enhance the performance of existing HPGe detectors for high-energy γ -rays. In addition, the BGO shield as a standalone detector allows for a use with the selective detection of positron annihilation. The compact geometry was optimized to use it with ELIADE, the HPGe array at VEGA (ELI-NP). We present the design, results from two commissioning runs with high-energy γ -rays and an outlook to future applications.
