The invention discloses a main radial probe signal calibration system and method for a cyclotron. The main radial probe signal calibration system comprises a main radial probe body, a main radial probe control cabinet, a radio frequency unit body, a radio frequency unit control cabinet and a main control computer. The main radial probe unit can transmit a probe to different radiuses of the cyclotron; a beam current is blocked by using the probe to form a current signal; and then the main radial probe control cabinet is used for measuring the current signal. The radio frequency unit can generate a high-frequency electromagnetic field to cause the interference on the measurement of the intensity of the beam current. The main control computer is used for realizing the control of the main radial probe unit and the radio frequency unit and running a calibration program and provides user interface, processing and storage functions and the like.
Description
technical field [0001] The invention relates to a signal calibration system and method, in particular to a main radial probe signal calibration system and method for a cyclotron. Background technique [0002] The beam current intensity is an important performance parameter of a cyclotron. Accurate measurement of beam current intensity is of great significance for the debugging of cyclotron performance, optimization of key parameters, and detection of operating status. [0003] For the measurement of cyclotron beam current intensity, the noise sources mainly include: high-frequency electromagnetic field interference introduced by radio frequency unit, environmental noise introduced by transmission line, power supply system interference, temperature fluctuation and noise introduced by vibration, etc. Among them, the high-frequency electromagnetic field interference introduced by the radio frequency unit is far greater than the influence of other interference, and it is diffic...
