Reduction in weight and power consumption of a gamma-ray spectrometer for space use

热设计优化已被证明是非常有效的，以减少重量和功耗的空间使用的γ射线谱仪。与月球探测卫星“月亮女神”上的制冷机相比，制冷机的重量功耗分别降低了1/3和1/10。“此外，更小、噪音更小的冷却器可以预期地降低颤噪噪声，这将大大有助于提高光谱仪的能量分辨率。

Optimization of thermal design has been verified to be extremely effective to reduce weight and power consumption of a gamma-ray spectrometer for space use. As a result of this research, the power consumption of weight of the cryocooler have been reduced to 1/3 and 1/10 respectively, compared to that aboard the lunar exploration satellite "Kaguya." Furthermore, a smaller and less noisy cooler leads to the expected reduction in microphonic noise, which will greatly contribute to the improvement in energy resolution of spectrometers.
