A general semiconductor spectrometer for detecting cosmic radiation

摘要

A useful model is the semiconductor spectrometer used to detect cosmic radiation from particles,It can be used in kubesat type ultra small spacecraft. Essence: the spectrometer comprises three printed circuit boards (1) and a digital signal processing circuit board (2)An end face (6) mounted between the two walls. Each of the three printed circuit boards (1) comprises a semiconductor detector (5),Equipped with passive protection device (3),The node of amplifier and signal generator,Close to the detector (5). In this case, the detectors (5) of all three boards (1) are located in sosno. The digital signal processing board (2) is provided with a micro controller,Flash device and driver chip with external interface. On the side of the first printed circuit board (1), the spectrometer is closed with a cover,There is a charged particle flux hole. Technical results: by arranging the detector and amplifying circuit on the same board and forming a signal, the spectral measurement performance of the detector was improved,This eliminates the possibility of using unshielded cables when connecting detectors,Therefore,Spectrometers are allowed to be used on very small spacecraft. 2 ZP。 F-L，Three liters.
