This experiment consisted of two io
This experiment consisted of two ionization chambers mounted 60 deg apart on the equator of the GREB 3 satellite along with a sun aspect sensor and telemetry antennas. These detectors were designed to measure solar X rays in the 2 to 8-A and 8 to 20-A bands and were mounted behind permanent magnets to shield them from penetration by energetic protons (less than 1 MeV) and electrons (less than 1 MeV) in the Van Allen radiation belts. Each magnet and its aluminum retaining cover effectively limited the detector look cone to an angular diameter of approximately 60 deg. The spectral sensitivity of the X-ray detectors was determined by their aluminum windows and nitrogen gas filler. The solar aspect sensor was a vacuum photocell behind a specially designed aperture and was designed to measure the angle between the sun and the satellite's equatorial plane. Data handling was essentially the same as that used for the GREB 1 X-ray experiment. Current from the ionization chambers was measured by a feedback-stabilized electrometer amplifier. Data were then telemetered to the ground using real-time FM/AM telemetry and were recorded by NASA minitrack stations on magnetic tape. The failure of the GREB 3 satellite to separate from Injun 1 resulted in a complicated tumbling motion of the composite satellite, which made it generally impossible to identify unambiguously an X-ray response from one or the other ion chamber. Therefore, no data from the 2 to 8-A detector were obtained. Data from the 8 to 20-A detector, however, were obtained from favorable ion chamber-aspect sensor geometry configurations (69 observations) and from close coincidences between the 8 to 20-A detector and solar aspect sensor responses (32 observations). The ion chambers also suffered from three types of energetic particle interference: (1) inner-zone protons with E>1 MeV, (2) high-energy solar protons associated with solar proton events, and (3) high-energy outer-zone electrons (the strongest source of particle contamination). Data were obtained for the period June 29 to November 26, 1961.

该实验由两个电离室组成，两个电离室以60度的距离安装在GREB 3卫星的赤道上，同时还配备了太阳纵横比传感器和遥测天线。这些探测器设计用于测量2至8A和8至20A波段的太阳X射线，并安装在永磁体后面，以防止它们被高能质子（小于1 MeV）和电子（小于1 MeV）穿透。 ）放在Van Allen辐射带中。每个磁铁及其铝制护盖均有效地将检测器视锥限制在大约60度的角直径内。X射线探测器的光谱灵敏度由其铝窗和氮气填充物确定。太阳高宽比传感器是一个经过特殊设计的孔径后面的真空光电管，旨在测量太阳与卫星之间的夹角。赤道平面。数据处理与GREB 1 X射线实验所使用的基本相同。通过反馈稳定的静电计放大器测量来自电离室的电流。然后，使用实时FM / AM遥测技术将数据遥测到地面，并由NASA微型跟踪站记录在磁带上。GREB 3卫星无法与Injun 1分离，导致复合卫星发生复杂的翻滚运动，这使得通常无法明确地识别来自一个离子室或另一个离子室的X射线响应。因此，没有获得来自2至8A检测器的数据。但是，来自8至20A检测器的数据 从有利的离子室角度传感器几何配置（69个观测值）以及8至20A检测器与太阳角度传感器响应（32个观测值）之间的重合获得了结果。离子室还遭受三种类型的高能粒子干扰：（1）E> 1 MeV的内区质子；（2）与太阳质子事件相关的高能太阳能质子；（3）高能外区电子（最强的颗粒污染源）。获得了1961年6月29日至11月26日的数据。（3）高能外区电子（最强的粒子污染源）。获得了1961年6月29日至11月26日的数据。（3）高能外区电子（最强的粒子污染源）。获得了1961年6月29日至11月26日的数据。
