- Abstract:
- A simple measurement method of DC electron beam trajectory was designed.With this measurement method,some experimental studies of trajectory of electron beam confined by permanent magnet (PM) were researched.Some experiment data of PM ring which can restrain the electron beam at 60~80 keV were gotten.The results show that the measurement method is convenient and effective,the results are comparatively accurate,PM have an evident focusing effect on electron beam,and this effect has a certain regularity.It laid a foundation for future farther study on magnetically-confined electron beam by means of permanent magnets.
