Title: IMAGE COLLECTION DEVICE FOR RADIATION CHAMBER
Abstract:
An image collection device for a radiation chamber comprises an electron accelerator (1) and an under-beam transmission device (2) that are mounted in the radiation chamber. An image collection device is mounted outside a radiation wall (3) at one side of the radiation chamber. The image collection device comprises at least two L-shaped reflection bent pipes (4). Two adjacent L-shaped reflection bent pipes (4) are connected by means of connecting pipes (5). The bent of each adjacent L-shaped reflection bent pipe (4) is provided with a reflector (41). An opening at the front end of the upmost L-shaped reflection bent pipe (4) directly faces to the radiation chamber, and an image pickup device is disposed at the position of an opening at the back end of the bottommost L-shaped reflection bent pipe (4). An image is reflected by multiple times, image information is collected, rays are reflected by several times, and the intensity of the rays is attenuated, and therefore, the rays can be prevented from damaging the image pickup device.
