Embodiment Construction

[0023] The present invention will be described in detail below with reference to the drawings and embodiments.

[0024] See figure 1 , The present invention provides a system principle diagram for radiation safety interlocking of the electron beam energy threshold based on the monitoring of the internal microwave power of the accelerator tube. The microwave power signal is collected from the accelerator tube, and the microwave power signal is demodulated into amplitude and phase signals. Calculate the required microwave power and amplitude of the electron energy threshold according to the efficiency of the accelerator tube. The comparison acceleration tube Weber gave the relationship between amplitude and threshold amplitude. When the microwave power amplitude of the accelerator tube is less than the threshold amplitude, the microwave source power switch is turned on; otherwise, the microwave source power switch is turned off.

[0025] See figure 2 , The present invention provi...

Abstract

The invention discloses a radiation safety interlock system device for on-line monitoring of an electron energy threshold in an electron linear accelerator. The device comprises a microwave acquisition system, a microwave amplitude-phase monitoring system, a quick comparison circuit and a microwave source control system. According to the device, the electron energy threshold in the electron accelerator can be monitored online in real time and fed back in real time, when the electron energy exceeds a certain threshold, the accelerator system is subjected to radiation safety interlock, so that an effect of radiation safety protection is achieved. The device has the advantages of absolute threshold control, real-time online monitoring, no influence on accelerator operation, and fast system reaction time up to 100 ns.

Description

Technical field [0001] The invention relates to a radiation safety interlock system device based on online monitoring of a linear accelerator electronic energy threshold. Background technique [0002] With the continuous progress and development of the fourth-generation light source technology free electron laser technology, high-energy linear electron accelerators have once again become active on the stage of history. For linear electron accelerators used in free electron laser devices, the X-rays, gamma rays, neutrons and other high-energy particle beams they produce have a positive correlation with the energy of the electron beams in the accelerator. In order to reduce the radioactive pollution of the linear electron accelerator to the nearby environment and the personal injury to the scientific research personnel, it is an effective method to control the electron beam energy in the linear accelerator below a certain threshold. [0003] For linear electron accelerators used in ...
