Abstract
The invention discloses a center electrode and an accelerating tube applying the same. The center electrode is composed of two mutually symmetrical V-shaped electrodes and the center electrode is in a shape of double V-discs. Two V-shaped corrosion resistant plates are located on the same horizontal line and an open mouth is formed between the two V-shaped corrosion resistant plates. The center electrode and the accelerating tube applying the same solve the problems that the accelerating tube is low in anti-pressure level and the axial electric field distribution is extremely not uniform in the prior art. The double-V-shaped center electrode is installed between two adjacent alumina ceramics loops so as to enable the accelerating tube to acquire a better and uniform axial electric field distribution. The anti-pressure level of the accelerating tube is improved and a secondary electron emission can be avoided. The interior electro-discharge can be brought about to affect the normal working of the accelerating tube.
Description
Technical field
The present invention relates to a kind of target and used the accelerating tube of this target, belonged to the accelerator art field.
Background technology
Accelerating tube is an important critical component of accelerator, and its tube wall is comprised of the alumina ceramic ring that welds.
In not adding the accelerating tube of target, axially Potential distribution is extremely inhomogeneous.Near the average field intensity of the whole accelerating tube of electric field ratio electrode is much bigger, especially near electron gun.In order to improve the withstand voltage level of accelerating tube, change the inhomogeneous state of axial electric field distributed pole, its main path is that accelerating tube is taked enforceable even measure.
Summary of the invention
Technical problem to be solved by this invention provides a kind of target and uses the accelerating tube of this target, and axial electric field distributes to make accelerating tube can obtain preferably uniformly, has improved the withstand voltage level of accelerating tube.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of target is comprised of two symmetrical V-type electrodes, is two V dish formulas, and described two V-type corrosion resistant plates are positioned at the same level line, and are provided with opening between the two.
Aforesaid a kind of target is characterized in that: two mutually close ports of described two V-type electrodes all are equipped with the aluminium ring.
Aforesaid a kind of target is characterized in that: described V-type electrode is the magnetism-free stainless steel material, and thickness is 1mm-2mm.
A kind of accelerating tube of using such as target as described in any one among the claim 1-3, comprise a plurality of alumina ceramic rings that are welded, between described adjacent two alumina ceramic rings target is installed, described target is connected with dispatch from foreign news agency pole piece on the described alumina ceramic ring.
The invention has the beneficial effects as follows: double V-shaped target has the function of improving the whole field uniformity of accelerating tube, can play shielding action to a certain degree, makes the electronics of dispersing be unlikely to bombard on the inwall of alumina ceramic ring; By double V-shaped target is installed between adjacent two alumina ceramic rings, axial electric field distributes to make accelerating tube can obtain preferably uniformly, improved the withstand voltage level of accelerating tube, avoided occuring secondary, caused internal discharge and affect accelerating tube normal operation.
