According to the positron-positron magnetic spectrometer, the integrated positron-positron magnetic spectrometer probe is adopted, and positron-positron energy spectrums with energy ranging from dozens of keV to hundreds of keV can be measured at the same time.
Description
technical field [0001] The invention relates to the technical field of magnetic spectrometers for space detection, in particular to a positive and negative electron magnetic spectrometer. Background technique [0002] A magnetic spectrometer is an instrument that uses a magnetic field to measure the momentum of charged particles or the flux of charged particles with different momentums. The working principle of the magnetic spectrometer is based on the basic physical law of uniform circular motion of charged particles around the magnetic field lines in a constant magnetic field. Under the action of a uniform magnetic field, the charged particles make a uniform circular motion (also known as Larmor motion), and their radius is proportional to the momentum of the charged particles. Magnetic spectrometers were first used in physical and chemical experiments on the ground for mass spectrometry. [0003] In 1958, the first artificial earth satellite was launched, and mankind en...
