Description
Technical field
The utility model relates to the irradiation devices in a kind of radiation processing technology field, but the irradiation devices that especially a kind of double source is drawn.
Background technology
Painted and the environmental contaminants radiation treatment of irradiation such as irradiation processing is that gamma-rays that the X ray that utilizes high-power electron beam, electron beam to practice shooting to produce or radionuclide are emitted carries out that macromolecular material preparation, food storage are fresh-keeping, medical supplies radiosterilization, medicine radiation sterilization, the maintenance of commodity irradiation, crystal and pearl etc.Irradiation processing industry is considered to a kind of economic benefit height, energy savings is saved manpower, non-harmful new process systems, be widely used in every field such as agricultural, industry, health care, its role in national economy and people's lives is remarkable day by day.
General application accelerator produces the electron beam of certain energy, these accelerators comprise: row ripple or wave ekctrinl inear accelerator, the high direct voltage accelerator contains: electrostatic accelerator, insulating core transformer type accelerator, multivoltage accelerator, electrocurtain accelerator, dynamitron accelerator etc.Electron beam extraction irradiation devices as shown in Figure 1, comprise electron linear accelerator 1, be installed in the scanning magnet 3 on the electron linear accelerator 1 and the scan box 4 of triangle by flange 2, be installed in the titanium window 10 that goes out to restraint the position on the scan box 4 over against electron linear accelerator, and be installed in the chilled(cooling) water return (CWR) 9 that scan box 4 bottoms are used to cool off titanium window 10, wherein chilled(cooling) water return (CWR) 9 is by cooling water inlet 8, coolant outlet 12 external cooling water systems; During work, the scan mode of scanning magnet 3 is bilateral scanning, i.e. the positive and negative half period that respectively accounts for of sweep current.The irradiation devices of this kind structure carry out irradiation processing after directly electron beam 5 being drawn through scan box 4 devices such as grade usually, utilize electron beam to carry out irradiation processing and have advantages such as power is big, efficient is high, security performance is good, but, can only be used for the little or thin article object of volume because the penetration depth of electron beam is less.For the impartible greatly again article object of volume, as the log desinsection, effect is bad.Simultaneously traditional titanium window formula irradiation devices scan box is very high to the stability requirement of scanning magnet, if scanning magnet 3 breaks down at work, even the moment that the time is very short, electron beam 5 causes severe impairment can for titanium window 10, even damages the whole system that comprises electron linear accelerator 1 and scan box 4.
When carrying out radiation treatment for the impartible greatly again article object of volume, usually use X ray extraction irradiation devices, X ray extraction irradiation devices structure as shown in Figure 2, comprise electron linear accelerator 1, be installed in scan box 4 on the electron linear accelerator 1, be installed in out the target 7 of intrafascicular heart position by flange 2, and be installed in the chilled(cooling) water return (CWR) 9 that scan box 4 bottoms are used for cooled target 7, wherein chilled(cooling) water return (CWR) 9 is by cooling water inlet 8, coolant outlet 12 external cooling water systems.Utilize the electron beam target practice generation X ray of electron linear accelerator 1 output to carry out irradiation processing.X ray has the big advantage of penetration depth, can carry out irradiation processing to the bulky items object, but because it is to be practiced shooting by electron beam to convert, its efficient of electron beam irradiation is lower relatively.
In existing accelerator irradiation device, or just electron beam is drawn and is carried out irradiation, or just electron beam is practiced shooting and produced X ray and carry out irradiation, and their irradiation object has certain limitation.
The utility model content
(1) technical problem that will solve
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of irradiation devices that can draw electron beam and two kinds of irradiation bombs of X ray simultaneously are provided.
(2) technical scheme
For achieving the above object, the utility model adopts following technical scheme:
But the irradiation devices that double source described in the utility model is drawn comprise electron linear accelerator, are installed in scan box on the electron linear accelerator by flange, on scan box, scanning magnet is installed, it is characterized in that being provided with on the scan box target and titanium window near the position of electron linear accelerator.
Wherein said target is arranged on the dead ahead of the electron beam that electron linear accelerator produces.
Wherein said titanium window is positioned at the left side or the right side of target.
Wherein said target is arranged on the skin parallel with the titanium window, is outer target structure; Perhaps being arranged on titanium window inside, is interior target structure.
Also be provided with the cooling water channel that is used for cooled target and titanium window on the wherein said scan box.
(3) beneficial effect
But the advantage and the good effect of the irradiation devices that double source described in the utility model is drawn are: the utility model structure comprises electron linear accelerator, scan box, target and titanium window, the function of integrated existing electron beam extraction irradiation devices and X ray extraction irradiation devices is in one, when scanning magnet was worked, accelerator irradiation device was drawn electronic beam current; When scanning magnet is not worked, then draw X ray.Be that device of the present utility model can be drawn electron beam and two kinds of irradiation bombs of X ray, with the processing request of the irradiated material object that satisfies different volumes.But utilize irradiation devices that double source described in the utility model draws to enlarge range of application increasing hardly under the condition of cost, if break down in drawing the mode of electron beam owing to scanning magnet simultaneously, be that scanning magnet is not when working, then electron beam is practiced shooting along forward direction and is produced X ray, can not produce infringement to the titanium window, the security performance height of system, but help improving the life-span and the utilance of the irradiation devices that the utility model double source draws.
