Abstract

The invention discloses a medium-energy proton detector, which comprises a probe and an electronics part, and is characterized in that the probe is used for outputting charge pulses of medium-energy protons to the electronics part; wherein the detection energy range of the medium-energy protons is 20 KeV to 5 MeV; and the electronics part is used for processing the received charge pulse and obtaining the energy of the medium-energy protons by analyzing the amplitude of the pulse signal. According to the detector, the detection range of the medium-energy protons can be as low as 20 KeV, the medium-energy protons are connected up to the detection energy sections of the high-energy protons and partially coincide down with the detection energy sections of the plasmas, so that all-energy-spectrum seamless measurement, fine energy spectrum measurement and high-direction resolution measurement can be achieved, and therefore energy transmission and distribution state changes of space particlesare monitored. The detector is of great significance to research of magnetic tail ground energy transportation and global radiation environment modeling, and can perform early warning on solar protonevents.

Description

technical field [0001] The invention relates to the field of aerospace, in particular to a space-borne medium-energy proton detector. Background technique [0002] Medium-energy proton detectors (energy range 20KeV~5MeV) are easily polluted by other particles and sunlight due to the extremely low deposition energy of the measured particles in the sensor (the lower limit of deposition energy is 10KeV), and it is difficult to realize them. on board. [0003] The current similar loads are mainly high-energy particle detectors, including high-energy proton, electron, and heavy ion detectors. , the current particle radiation detectors are generally at 10 5 unit / s, it is very easy to reach saturation in space environment events such as magnetic storms and solar proton events. [0004] There are many reasons that restrict the development of this type of load to low-energy detection. In addition to the selection of sensors and front-end circuits, it also includes the design of no...
