Abstract
Provided is a ray collimating device used for a standing wave electron linear accelerator. A 24V DC power supply is connected with a power conversion module through a power line. The power conversion module converts voltage and then is connected with a red diode through a power line. Two laser fixing supports are respectively fixed above a side of a shielding device ray window of the standing wave electron linear accelerator and on the left of the shielding device ray window, wherein the central position of the fixing support above a side of the ray window and the central position of the ray window are on a vertical line. The central position of the fixing support on the left of the ray window and the central position of the ray window are on a horizontal line. The red diode is fixed in the hole of the laser fixing support. The device uses design of red light visible band laser semiconductor, and red light line laser calibration is characterized by high precision, external contract measurement, and is rapid, thereby preferably solving problems of calibration bias of central axis points of a measured object and a ray emission beam, and greatly saving calibration time.
