粒子分光术传感器将搭载在2005年日本发射的第一次月球使命的SELENE航天器上，它将测量高能宇宙射线粒子，以便为今后人类活动测量月球周围的辐射环境，并研究它们在太阳系中的加速和传播。PS传感器由4个探测器组成：高能同位素探测器（HID）、低能重离子粒子探测器（LPD-HE）、低能质子粒子探测器（LPD-p）和低能电子粒子探测器（LPD-e）。这些是使用/spl Delta/E /spl times/ E方法的Si固定探测器，其分别覆盖质子的能量范围从100 keV到60 MeV，电子的能量范围从30 keV到几MeV，以及重离子的能量范围从3 MeV/n到400 MeV/n。我们使用了一种新型的B/sup +/掺杂Si（Li）探测器，其厚度为1 ~ 6 mm，每个传感器具有高能量分辨率。利用PS传感器可以对He ~（3+）重离子的同位素进行识别。
The PS (particle spectroscopy) sensor, that will be onboard the SELENE spacecraft for the first Japanese lunar mission to be launched in 2005, will measure the high energy cosmic ray particles to measure a radiation environment around the moon for human activities in the future and to study their acceleration and propagation in the solar system. The PS sensor consists of 4 detectors: high energy isotope detector (HID), low energy particle detector for heavy ions (LPD-HE), low energy particle detector for proton (LPD-p) and low energy particle detector for electron (LPD-e). These are Si stuck detectors using the /spl Delta/E /spl times/ E method that cover the energy range from 100 keV to 60 MeV for proton, from 30 keV to a few MeV for electron and from 3 MeV/n to 400 MeV/n for heavy ions, respectively. We use a new type B/sup +/ doped Si(Li) detector of which thickness is from 1 to 6 mm with high energy resolution for each sensor. We can identify the isotopes for heavy ions from He to Xe by the PS sensor.
