The direct measurement of the energetic neutral atoms originating from the heliospheric termination shock and beyond as well as neutral interstellar gas penetrating into the heliosphere requires a very sensitive neutral particle imaging instrument in the energy range of 10-1000 eV. We present the development of the prototype of the low energy sensor for the Interstellar Boundary Explorer (IBEX) mission: IBEX-Lo is a neutral particle mass spectrometer dedicated to the measurement of energetic neutral atoms in this energy range. The response of the sensor to incident neutral hydrogen, helium, and oxygen atoms is discussed as well as the properties of the sensor's ion optics, the neutral-to-negative conversion surfaces, and other instrumental parameters.
直接测量源自日球层终端激波及更远区域的高能中性原子以及穿透日球层的中性星际气体，需要一台在10 - 1000电子伏特能量范围内非常灵敏的中性粒子成像仪器。我们展示了用于星际边界探测器（IBEX）任务的低能传感器原型的研制情况：IBEX - Lo是一台专门用于测量该能量范围内高能中性原子的中性粒子质谱仪。讨论了该传感器对入射中性氢、氦和氧原子的响应，以及传感器的离子光学特性、中性到负离子转换表面和其他仪器参数。
