Abstract

The invention provides a solar X-ray detector with a wide field angle and high energy spectrum resolution. According to the detector, a sun sensor senses that the sun enters a detection field, operation timing sequences of a peak protection circuit and a pulse height analyzer are started, solar X-rays enter a silicon drifting sensor through the detection field formed by a collimator and a diaphragm, and a high-energy electron enters the collimator and deviates from the incident direction under the action of a deflection magnet; electric charge pulses of solar X-ray photons in the silicon drifting sensor are converted, shaped and amplified to form voltage pulse signals through a pre-amplifier, a pulse shaping unit and a main amplifier, amplitude analysis is carried out on the voltage pulse signals through the peak protection circuit and the pulse height analyzer, the voltage pulse signals are sent to a computer A or a computer B of an FPGA master control circuit, the computer A or the computer B of the FPGA master control circuit receives detection data from the high-energy electron and a high-energy proton heavy ion interface circuit at the same time, energy spectrum data of the solar X-rays are processed, stored and coded, and the energy spectrum data are transmitted to a satellite platform through a computer A or a computer B of a coding telemetering interface circuit and a satellite electrical interface.

Description

technical field [0001] The invention belongs to the technical field of solar flare monitoring and space astronomical observation, and in particular relates to a solar X-ray detector with a wide field of view and high energy spectral resolution capable of monitoring disastrous space weather events such as solar flares in a geostationary orbit. Background technique [0002] The solar X-ray detector is an important device used in geostationary orbit satellites to monitor solar flares and other disastrous space weather activities, and can also be used for astronomical X-ray object detection. The solar X-ray detector classifies the level of solar flare activities according to the X-ray flux intensity released by the solar flare, and evaluates and warns of its disastrous impact; in addition, because there is a very strong charged particle radiation environment in the geostationary orbit, therefore, Solar X-ray detectors need to have extremely high detection sensitivity, energy spe...
