Description
Technical field
The present utility model relates to irradiation processing, nondestructive inspection and field of radiation therapy, particularly the beam guiding device of the ray of emitting with radiation source.
Background technology
Accelerator can produce high-power electron beam or the high-power electron beam target practice is produced X ray.Radiation treatment technology and radiotherapy are ionizing power and the bremsstrahlung effects of utilizing electron beam or X ray, make to be subjected to the photograph article to produce some biology and physical effect, thereby carry out the treatment technology of disinfection and deinsectization, change article physical characteristic or treatment tumour.Nondestructive inspection is to utilize the penetration capacity of X ray to object, surveys the internal structure of object.In the prior art, it is all very big to be used for auxilliary powerful electron accelerator volume and weight according to processing, in application process, the position is difficult to arbitrarily change, and for increasing irradiated area, generally uses the electromagnet scanning means, make electron beam expand to a capable bundle of line, draw by extraction window again.But also basic fixed is constant for the irradiation zone that scanning means produces, so require the photographed object product to pile up in strict accordance with irradiation zone.In nondestructive inspection and radiocurable application, need to change the position of accelerator or illuminated object with comparatively huge mechanical device.The shortcoming of this traditional line lead-out mode is: auxilliary according to the application of handling in, relatively stricter to the shape size requirements of photographed object product, can't satisfy volume greatly, the irradiation requirement of the irregular article of profile; At nondestructive inspection and radiotherapy, the mechanical driving device that needs is big, operation is inconvenient, cost is high.
Summary of the invention
For overcoming above-mentioned problems of the prior art, the purpose of the present utility model provides a kind of beam guiding device of electron beam, and it can change electronic beam current extraction location and direction flexibly, arbitrarily.In use, need not to change the position of accelerator or the position and the shape thereof of illuminated object.Only need that the line extraction window is moved to assigned address and get final product, make easy to operately, reduce the detection cost.
For reaching above-mentioned goal of the invention, technical scheme of the present utility model realizes as follows: a kind of beam guiding device of electron beam, it comprises electron accelerator, vacuum pump and flexible and flexible line flexible pipe, its design feature is that the two ends of described line flexible pipe are provided with introduces window and extraction window and make the sealing of line flexible pipe.The introducing window of line flexible pipe and the accelerating tube of described electron accelerator join.The extraction window of line flexible pipe can be placed on tested article part.The outer wall of line flexible pipe is provided with the coil winding that can use recirculated water cooling.The periphery of coil winding is provided with yoke.First section outer wall setting of line flexible pipe can make the vacuum pump of vacuum in the line flexible pipe and the coil power and the water-cooling system of coil winding are provided.
The present utility model has been owing to adopted said structure, can photographed object product position immobilize or the geostationary situation of accelerator position under, utilize the present utility model tested article to be shone from different angles and position, make flexible to operation.Because do not need to change the position of accelerator, make mechanical driving device simply light.That the present utility model can be applicable to is large-scale, out-of-shape or the auxilliary according on handling of specific (special) requirements object arranged, or is applied in nondestructive inspection and radiotherapy.In use be equipped with light mechanical moving device, just can finish the irradiation action flexibly, quickly and accurately.Have simple in structure, the low characteristics of detection cost.
