The alarm 4 is welded on one side of the top of the main control box 1 and connected to the computer 5 to monitor the range of various parameters inside the 9 cavities, such as monitoring the current and voltage of each cavity. If a parameter exceeds the safe range, the alarm 4 will sound a whistle to remind the indoor experimenter that a cavity has a fault, and transmit the fault information to the computer 5. If the fault information prompted in the computer 5 is not processed within a certain period of time, the computer 5 will send the fault information to the experimenter's mobile phone. The computer 5 is suspended and welded on the right side of the right cavity 2, which is convenient for the experimenter to operate and record the various parameters inside the 9 cavities in real time.
