Embodiment 1
[0040] This embodiment discloses a space particle detector, such as figure 2 As shown, it includes: one or more particle detectors 100 , a signal conditioning unit 200 , a data processing unit 300 and a power supply unit 400 . in,
[0041] The signal conditioning unit 200 is connected with one or more particle detectors 100 and the data processing unit 300 respectively; the power supply unit 400 is connected with one or more particle detectors 100 , the signal conditioning unit 200 and the data processing unit 300 respectively.
[0042] The particle detector 100 is used to convert particles incident thereon into charge pulse signals.
[0043] The signal conditioning unit 200 converts the charge pulse signal transmitted by one or more particle detectors 100 into an event data frame that can be used for cumulative counting after amplifying, shaping and other processing, and completes the event data frame within a given time and according to the instructions of the data proces...
Embodiment 2
[0063] This embodiment discloses an on-board data collection and processing method for a space particle detector, including: a particle event accumulative storage process and a particle event statistical reading process.
[0064] The particle event accumulation storage process is only completed within the gate opening time, specifically excluding:
[0065] (1) The particle sensor generates a particle event according to the particles incident on it;
[0066] (2) After amplifying the sub-module, a bell-shaped voltage pulse signal is formed;
[0067] (3) If the amplitude of the bell-shaped voltage pulse signal is higher than the preset amplitude threshold voltage, the trigger generates a trigger signal and provides it to the control module;
[0068] (4) After the control module receives the trigger signal, it generates a timing control signal to control the peak detection sub-module, thereby determining the peak position of the bell-shaped voltage pulse, and completing the sampl...
Embodiment 3
[0084] This embodiment is a medium-energy electronic detector that has been successfully applied to a navigation satellite IGSO (Inclined Geosynchronous Satellite Orbit) test. The instrument can simultaneously measure medium-energy electrons incident from 9 different directions, and each direction can measure 8 exponentially distributed energy levels ranging from 50keV to 600keV.
[0085] The main circuit function modules of the navigation satellite IGSO experimental neutral energy electronic detector can also refer to figure 2 , can be divided into a probe sensor (particle sensor 100 ), a signal conditioning unit 200 , a data processing unit 300 , and a power supply unit 400 .
[0086] The probe sensor includes 9 sensor units, each unit corresponds to an electron incident direction, and the 9 sensor units can cover a range of 180° opening angle. The sensor is used to form a charge pulse signal from the incident medium-energy electrons.
