MULTIPLE-POWER MULTIPLE-DOSAGE ACCELERATOR, RAPID EXAMINATION SYSTEM HAVING THE ACCELERATOR AND CORRESPONDING RAPID EXAMINATION METHOD

摘要

A multiple-power multiple-dosage accelerator, comprising: an electron gun that provides a first electron gun voltage and a second electron voltage; an accelerating tube that generates, according to the first electron gun voltage, a first X-ray having a first dosage and a first power, and generates, according to the second electron gun voltage, a second voltage and a second power, the first dosage being a dosage that a human body can receive and a dosage that far smaller than the second dosage; the first x-ray is used for examining a first area where personnel are, and the second x-ray is used for examining a second area where goods are. Additionally provided are a method for using the multiple-power multiple-dosage accelerator for sub-area inspection, and a ray detection system.
