Abstract
In the electron accelerator production and application industries, low loss is required in an electron transmission process and a long service life of an electron accelerating tube is required. In order to solve the problems, the utility model provides a disk-shaped electrode plate electron accelerating tube device of an electron accelerator. The device consists of flanges, electrode plates and insulating rings, wherein the electrode plates and the insulating rings are bonded one by one at intervals; the insulating rings are arranged at two ends; and the flanges are bonded on the insulating rings at the two ends respectively. The device is characterized in that: the electrode plates are disk-shaped; and in order to improve the bonding power between the electrode plates and the insulating rings, rounding chamfers are formed between the two side faces and the annular faces of the insulating rings. Through the device, the electrode plate structure of an electron accelerating tube is changed; the insulating rings of the electron accelerating tube are effectively prevented from being directly bombarded by electrons; the internal vacuum degree of the electron accelerating tube is improved; the beam current transmission efficiency is improved; and the service life of the electron accelerating tube is prolonged.
Description
Technical field
The utility model belongs to the electron accelerator technology, is specifically related to a kind of butterfly electrode slice electronics accelerating tube of electron accelerator.
Background technology
The electronic beam current transport process of electron accelerator, electronics accelerating tube inside is high vacuum, electronics accelerating tube external electric pole piece is connected with the resistor of certain resistance between any two, when there is voltage difference in the accelerating tube two ends, can form uniform electric field in accelerating tube inside, electron beam obtains quickening under this effect of electric field, realizes transporting of electron beam.At present, being used for to the equipment that the electron accelerator electronic beam current transports mainly is plate electronics accelerating tube.Electrode slice is plate shaped, when switching between two electrode slices, can form a flat field in accelerating tube inside, and line directly transports in accelerating tube, and therefore in the electron beam transport process, electronics can collide and the generation scattering with the residual gas molecule in the accelerating tube.The electronics accelerating tube of this flat pole sheet, because the insulating material between the electrode slice often is subjected to the bombardment of scattered electron, make the insulating material of electronics accelerating tube shorten useful life, the vacuum degree in the accelerating tube reduces, and has increased the loss of electron beam in transport process.
Summary of the invention
Vacuum is high more in the electronics accelerating tube of electron accelerator, then helps transporting of electronic beam current more; The useful life of electronics accelerating tube insulating material is long more, and then the useful life of electronics accelerating tube is long more.In electron accelerator production and application industry, it is little all to require electronics to lose in transmission course, and will grow the useful life of electronics accelerating tube.Be head it off, the utility model provides a kind of electronics accelerating tube with the disk-shaped electrode sheet, this device has changed the power on structure of pole piece of electronics accelerating tube, having shielded scattered electron directly bombards on the insulating material of accelerating tube, prolonged its useful life, and the material outgassing of having avoided the electron bombard insulating material to cause helps the raising of electronics accelerating tube internal vacuum, has reduced the loss of electron beam in transport process.
The technical scheme that the utility model provides is:
A kind of butterfly electrode slice electronics accelerating tube of electron accelerator is made up of flange, electrode slice, dead ring, the alternate one by one bonding of electrode slice and dead ring, and two ends are dead ring, flange is bonded in respectively on the dead ring at two ends, it is characterized in that electrode slice is a butterfly; Be to improve the cohesive force of electrode slice and dead ring, between the two sides of dead ring and ring surface, all be processed with chamfering.
Good effect of the present utility model is:
The butterfly structure of the electrode slice of electronics accelerating tube has shielded electron beam and has collided the scattered electron that causes in inner transport process of high vacuum electronics accelerating tube and residual gas molecule, has protected dead ring, has prolonged the useful life of accelerating tube; The material outgassing of having avoided scattered electron bombardment dead ring to cause helps the raising of electronics accelerating tube internal vacuum, has reduced the loss of electronic beam current in transport process.The chamfer design at dead ring two ends helps improving bond quality, guarantees the air-tightness of bonding part.

Embodiment
Below in conjunction with accompanying drawing, describe embodiment of the present utility model in detail, as shown in the figure, electrode slice 2 is butterfly structures made from stainless steel material, and alternate one by one bonding with dead ring 3, two ends are dead ring, and upper flange 1 and lower flange 4 are bonded in respectively on the dead ring at two ends, all are processed with chamfering between the two sides of dead ring 3 and ring surface.The butterfly structure of electrode slice 2, having shielded scattered electron directly bombards on the dead ring 3 of accelerating tube, prolonged its useful life, and the material outgassing of having avoided electron bombard dead ring 3 to cause, help the raising of electronics accelerating tube internal vacuum, reduced the loss of electron beam in transport process.Chamfering on the dead ring 3 can guarantee the air-tightness of electronics accelerating tube so that the carrying out of bonding process improved bond quality.
When using this accelerating tube, be connected with the pipeline that lower flange 4 and electronics add device by upper flange 1.When switching between two electrode slices, form a flat field in the inner meeting of accelerating tube, line directly transports in accelerating tube, under same line output condition, its vacuum degree can reach 10-5Pa, vacuum degree 10-4Pa than original plate electronics accelerating tube has improved an order of magnitude, in the line output procedure, its fluctuations of vacuum of electronics accelerating tube of butterfly electrode slice is less, the side has proved that the venting rate of material has reduced, and helps the raising of beam transport efficient and the prolongation in electronics accelerating tube useful life.
