Description
Technical field
The utility model relates to a kind of beam diagnostics equipment for accelerator installation, particularly relates to a kind of Faraday cylinder for high energy high-current accelerator device.
Background technology
Faraday cylinder is a kind of intercept type beam diagnostics equipment conventional in accelerator installation, and its effect is except halved tie stream carries out stop interception, and the stream being also used for measuring line is powerful little.Because be faraday's first design and use, so be often called Faraday cylinder.Its structure is generally a cylindric passive electrode, when line (set of charged particle) bombardment is on electrode, is collected by electrode interception, and the electrically charged resistance that flows through of line institute forms loop, thus the stream recording line is strong.
Faraday cylinder is as a kind of intercept type beam diagnostics equipment, and when line is blocked, its energy can will be deposited on Faraday cylinder interception face, and shows with the form of heat energy.For high energy high current line, the temperature in Faraday cylinder interception face rises to very high very soon, even by the material melts in interception face, causes damage to Faraday cylinder.In order to prevent Faraday cylinder from damaging, the measure taked is the dystectic material of material selection in interception face, or is passed fast by the heat energy on interception face, or reduces the beam power in unit area.
What the Faraday cylinder used at present was mostly taked is first two measure, and its structure is cylinder barrel shaped structure, material or be copper, or is high melting point metal materials tantalum or tungsten.And copper fusing point is lower, directly in the face of high energy high current line is very easily damaged.For high energy high current line, general way forms water-cooled body for being equipped with water cooled pipeline on copper body, then the cylindrical drum of tantalum or tungsten is welded on water-cooled body.Although the cylindrical drum of tantalum or tungsten and water-cooled body are welded together, their contact is generally face contact or the point cantact of part.This is because will the cylindrical drum of tantalum or tungsten be put in the cylinder shape groove of copper water-cooled body, must there is certain gap between the cylindrical drum side external surface of tantalum or tungsten and the cylinder shape groove side inside surface of copper water-cooled body, their connection only links together by solder.Even if inside surface processing is very smooth at the bottom of the cylinder shape groove cylinder of outside surface and copper water-cooled body at the bottom of the cylindrical drum cylinder of tantalum or tungsten, but also can only be face contact or the point cantact of part between them, can not be face contact completely.Because be face contact or the point cantact of part, the effect of heat trnasfer is had a greatly reduced quality, the limited efficiency of water-cooled.
The stream that Faraday cylinder is used for measuring line is powerful little, and this just needs the miscellaneous part insulation of Faraday cylinder and equipment to come, and the current signal can completely produced because of line is gone out by cable transmission.Line bombardment can produce secondary electron and overflow on interception face, and the precision that impact is measured, in order to suppress secondary electron, needing to add a high-field electrode in Faraday cylinder line porch and overflowing to suppress secondary electron.Meanwhile, also need electrode, Faraday cylinder, water inlet pipe and water outlet pipe etc. to be wrapped up with baffle plate, the object done like this has following 3 points: one, protect baffle interior insulating material not by line irradiation, because insulating material can be deteriorated by insulating property after line irradiation; Two, electrode and Faraday cylinder Heat Conduction Material are copper, by line Long-Duration Exposure, can make member; Three, in beam current tube space, certain charged particle is also distributed with, these charged particles can affect the measurement of Faraday cylinder to Bunch current, Faraday cylinder is surrounded by baffle plate, baffle plate is connected with device housings and beam current tube again, and the charged particle of such space distribution would not affect the measurement of Faraday cylinder to Bunch current.In order to the insulation of the miscellaneous part of high-field electrode, Faraday cylinder, baffle plate and equipment be come, traditional project organization is comparatively complicated, makes troubles to assembling and maintenance.
Faraday cylinder is usually with driving arrangement, when not using by driving arrangement away from beam-flow transmission line, do not affect the transmission of line, moved on beam-flow transmission line by driving arrangement in use, stop that line passes through, measure Bunch current size simultaneously.By Faraday cylinder and driving arrangement integrally, after Faraday cylinder damages, whole equipment all can be scrapped, and cannot recycle in traditional design, and Faraday cylinder is fixed relative to the direction of equipment simultaneously, unadjustable, makes troubles to installation.

Described high energy high-current accelerator Faraday cylinder, the material in described circular platform type interception face is the tantalum plate that dystectic 1 ~ 2mm is thick.The material of the vertex of a cone is dystectic tantalum or tungsten.
The beneficial effects of the utility model: taken into full account following measures, namely tackle the dystectic material of material selection in face, the heat energy on interception face passed fast, the beam power reduced in unit area, be taper barrel structure by Faraday cylinder structural design.Interception face adopts the thick tantalum of 1 ~ 2mm to be made as taper cone barrel, to be sleeved on the water-cooled body with cone-shaped groove and to weld together.Why be designed to taper barrel structure, because Faraday cylinder is when tackling line or measuring Bunch current, the axis of taper cone barrel and the transmission direction of line overlap, except the vertex of a cone is vertical with beam transfer direction, taper cone barrel inside surface all has certain angle with beam transfer direction, thus increase the contact area in line and Faraday cylinder interception face, reduce the power of unit area line.
The size of taper cone barrel cone angle is relevant with the beam power blocking the unit area that section material can be born, and the beam power of unit area is larger, requires that circular cone cone angle is less, to increase the area in interception face, thus causes circular cone axial length longer.It is very difficult that the difficulty brought is exactly tapered interior surface (comprising the inside surface of interception face taper cone barrel and the inside surface of water-cooled body cone-shaped groove) processing, if the precision of processing is not high, be difficult to ensure after interception face taper cone barrel welds together with heat conductor to be face and the contacting of face.The difficulty simultaneously brought is the processing of conical top, because centrum axial length is longer, cone angle is less, adds the restriction of cutter, and the conical top processed is not a point, but the cambered surface that slight.Particle density is become to the line of Gaussian distribution, the beam power of beam center place unit area is maximum, and it is approximate vertical with beam direction again that little cambered surface is in beam center, thus cause the vertex of a cone to be easy to be damaged by line.
In order to overcome above-mentioned difficulties, we have done following improvement, and 1, to be divided in the Faraday cylinder face of tackling circular platform type to tackle face and vertex of a cone two parts.Circular platform type interception face is the conical tube of the tantalum making that 1 ~ 2mm is thick, and conical tube top is opening.Because the particle density of line becomes Gaussian distribution, the unit area beam power at line edge is less, so become by the subtended angle bottom taper cone barrel large to reduce the axial length of taper cone barrel.The vertex of a cone is the small cylinder that tantalum makes, and machined a conical recess in the axial direction, its inside surface can and circular platform type tackle face smooth interior surfaces transition, form a complete tapered interior surface.Because the vertex of a cone is shorter, processing conical recess ratio is easier to, and the groove top processed is a point.2, a columniform opening is done at water-cooled body conical recess top, and its size is slightly less than the vertex of a cone.3, first circular platform type is tackled face and the welding of water-cooled body during welding.Circular platform type being tackled surface cover to enter in the conical recess of copper water-cooled body and utilize mould their to be compressed shaping guarantee again between them is face contact, and and puts together with the mould of compression and weld in a vacuum furnace.Removes mould after welding is good and circular platform type interception face cone top portion is repaired, with ensure its inside surface can and vertex of a cone groove inside surface form a complete and smooth conical surface.4, pack in the cylinder shape groove at copper water-cooled body top by the technique of cold cover or hot jacket by the vertex of a cone, vertex of a cone diaphragm seal and the vertex of a cone compress afterwards and water-cooled body welds together, and are sealed in by the vertex of a cone in water-cooled body.
