| Abstract: | An electron beam measurement system for TWT is built and tested. The thermal analysis of the Faraday
cup probe of the system is described. The pulse temperature and steady-state temperature of the probe have been
calculated and simulated by using ANSYS software. The probe would rise a high temperature during the pulse, but the
steady-state temperature is low. The experiment showed that the steady-state temperature of the probe was higher than the
simulation results but lower than the broken temperature. This Faraday cup probe is applicable for the electron beam
measurement system. |
