Problems solved by technology

This kind of electron beam ion trap that applies a constant voltage on the two electrodes and accelerates electrons by generating an electrostatic field has the following disadvantages: the energy of accelerating electrons is low, and the electron beam energy of most devices is lower than 100KeV; the device with electron beam energy higher than 100keV The volume is too large. In order to avoid the air breakdown discharge caused by the high-voltage electrostatic field, a high-voltage sulfur hexafluoride insulating gas system must be used, so that this type of device occupies 2 floors or more; when the electron beam energy is higher than 80keV , the ignition phenomenon of the high-voltage electrostatic field is very serious, which affects the stable operation of the system; the thermal electrons emitted by the cathode material are non-polarized electron beams, that is, the electron spin direction is randomly distributed, and the polarized electron beam and ion cannot be carried out. crash study
