Abstract
In the working process of an electron accelerator, the transport of an electron beam is invisible in an electron accelerating tube, and the transport of the electron beam is difficult to monitor in an electron accelerating tube section. In order to solve the problems, the invention provides an electron beam monitoring device, which is characterized by consisting of four probes, two flanges and a pipeline. Two sides of the pipeline is welded with the flanges; each probe consists of a receiving board, a joint, a Kovar insulation sleeve and four shaft rods; the receiving board is fixedly connected with one end of the shaft rods inserted into inside the pipeline through a bolt; the joint is sleeved on the shaft rods and fixedly welded with the outer wall of the pipeline; the Kovar insulation sleeve is sleeved on the shaft rods, one end of the Kovar insulation sleeve is welded with the joint, and the other end of the Kovar insulation sleeve is welded with the shaft rods; and the probes are uniformly and circumferentially installed on the same vertical plane of inner side of the pipeline. The device detects whether improper transport statuses such as broken stream occur during the outputting electron beams of the electron accelerator through a beam signal output by the monitoring probes, thereby providing objective basis for the diagnosis of beam statuses of the electron accelerator and contributing to improvement on the safe reliability of the electron accelerator.
Description
Technical field
The invention belongs to the electronic beam current monitoring technology, be specifically related to a kind of electron accelerator electronic beam current monitoring device.
Background technology
In the electron accelerator course of work, electronic beam current is sightless transporting of electronics accelerating tube, and to quicken the monitoring that pipeline section carries out the situation that transports of electronic beam current at electronics also be the comparison difficulty.At present, the industrial electronic irradiation accelerator is for the not enough attention of the monitoring of line, and the beam transport situation is judged in the vacuum variation that causes when generally also just transporting by electron beam is improper and the heating of vacuum pipe etc. indirectly.When electron accelerator during in big line output, be easy to can the erroneous judgement electron beam improper transport that the vacuum that causes changes and the phenomenons such as heating of vacuum pipe during by line greatly the edge electron scattering of line envelope caused.Line is improper to be transported under the state when electron accelerator is operated in, and very easily electronics accelerating tube, vacuum pipe etc. is caused major injury and destruction.
Summary of the invention
Be head it off, the invention provides a kind of electronic beam current monitoring device, this device utilizes electronic beam current to be similar to the characteristic of electric current, promptly becomes electric current when scattered electron bombards on metal.Judge by the situation of measuring electric current whether the big line of electron accelerator has electron beam to depart from the original track that transports when exporting.
Technical scheme provided by the invention is:
A kind of electron accelerator electronic beam current monitoring device is characterized in that being made up of probe, flange and pipeline.Pipeline two sides and flange welding, probe is made up of dash receiver, joint, kovar insulating case and axostylus axostyle, dash receiver is fixedlyed connected with the end of axostylus axostyle in inserting pipeline by screw, fitting sleeve on axostylus axostyle and and pipeline outer wall welding fix, the kovar insulating case is enclosed within on the axostylus axostyle, one end and joint welding, the other end and axostylus axostyle welding, popping one's head in evenly to be circumferentially is installed on the same vertical plane of insides of pipes.
Good effect of the present invention is:
Popping one's head in evenly to be circumferentially is installed on the same vertical plane of insides of pipes, can guarantee that signals that all probes are surveyed are that synchronization is conplane.The current signal that this device can provide by monitoring probe, the observation electron accelerator goes out the improper situations that transport the such as whether stream of loosing being arranged in the bundle process and occurs, for the line condition diagnosing of electron accelerator provides objective basis, help improving the security reliability that electron accelerator uses.

Embodiment
Below in conjunction with accompanying drawing, electron accelerator electronic beam current monitoring device with four probes is an example, describe the present invention in detail, as shown in the figure, pipeline 2 two sides are welded with lower flange 1 and upper flange 3 respectively, probe 4 is made up of stainless dash receiver 5, joint 7, kovar insulating case 8, axostylus axostyle 9, dash receiver 5 is installed in the end that axostylus axostyle 9 inserts in the pipeline by screw 6, joint 8 is enclosed within on the axostylus axostyle 9 and with the welding of pipeline 3 outer walls and fixes, kovar insulating case 8 is enclosed within on the axostylus axostyle 10, one end and joint 8 welding, the other end and axostylus axostyle 9 weld together.Four probes 4 are and circumferentially are placed in equably on the pipeline 2 inboard same vertical planes.Join with the beam guide pipeline at two ends, line position to be monitored respectively by upper flange 3 and lower flange 1 when using this device.On the signal output part 10 of four axostylus axostyles 9, connect ammeter, when electronic beam current passes through this beam monitoring device,, will can observe current signal on four receiver sheets 5 so if line has scattering; If line is not positioned at the center, and is partial to a certain side, the current signal of correspondence is stronger on this side dash receiver 5 so.
This electron accelerator beam monitoring device is installed on the 0.5MeV high frequency high voltage electron accelerator, and when electron accelerator output line was enhanced to big line gradually by little line, the current signal of its probe output strengthened gradually; By the application of this device, can observe electron accelerator and go out the improper situations that transport the such as whether stream that looses being arranged in the bundle process and occur, for the line condition diagnosing of electron accelerator provides objective basis.The situation that transports of monitoring line can be carried out some anticipations in advance in real time, improves the security reliability that electron accelerator uses.
