Description
Technical field
It is more particularly to a kind of to be used for high energy high current the present invention relates to a kind of beam diagnostics equipment for accelerator installation
The Faraday cup of accelerator installation.
Background technology
Faraday cup is a kind of intercept type beam diagnostics equipment commonly used in accelerator installation, and its effect is flowed into except halved tie
Row stops that interception is outer, also powerful small for measuring the stream of line.Because being faraday's design and use first, often it is referred to as
It is Faraday cup.Its structure is usually a passive electrode for cylindrical shape, when line (set of charged particle) bombardment is in electrode
On, being intercepted by electrode and collected, the electrically charged resistance that flows through of line institute forms loop, so as to the stream for measuring line is strong.
Used as a kind of intercept type beam diagnostics equipment, when line is intercepted, its energy can will be deposited on farad to Faraday cup
On interception face, and showed in the form of heat energy.For high energy high current line, Faraday cup intercepts the temperature in face quickly
Rise to it is very high, or even by intercept face material melts, to Faraday cup cause damage.In order to prevent Faraday cup from damaging, adopt
The measure for taking is the dystectic material of material selection in interception face, or the heat energy on interception face is quickly passed, or
Person reduces the beam power in unit area.
What the Faraday cup that is used mostly was taken at present is first two measure, and its structure is cylinder barrel shaped structure, material or
Person is copper, or is high melting point metal materialses tantalum or tungsten.And copper fusing point is relatively low, easily damaged directly facing high energy high current line
It is bad.For high energy high current line, general way is to form water-cooled body equipped with water cooled pipeline on copper body, then by tantalum or tungsten
Cylindrical drum is welded on water-cooled body.Although the cylindrical drum and water-cooled body of tantalum or tungsten are welded together, their contact one
As for part face contact or point contact.Because the cylindrical drum of tantalum or tungsten to be put into the cylinder shape groove of the cold body of copper water
In, there will necessarily be certain seam between the cylinder shape groove side inner surface of the cold body of cylindrical drum side external surface and copper water of tantalum or tungsten
Gap, their connection only leans on solder connection together.Even if the cylindrical drum cylinder bottom outer surface of tantalum or tungsten and the circle of the cold body of copper water
It is very smooth that cylindrical groove cylinder bottom inner surface is processed, but also can only be that the face contact of part or point are contacted between them, can not
It can be complete face contact.Because being the face contact or point contact of part so that the effect of heat transfer is had a greatly reduced quality, the effect of water-cooled
It is really limited.
The stream that Faraday cup is used for measuring line is powerful small, and this is accomplished by insulating the miscellaneous part of Faraday cup and equipment
Come so that because the current signal can completely that line is produced is gone out by cable transmission.Line bombardment can be produced on interception face
Raw secondary electron overflows, and influences the precision of measurement, in order to suppress secondary electron, it is necessary in Faraday cup line porch plus one
High-field electrode come suppress secondary electron overflow.It is also desirable to electrode, Faraday cup, water inlet pipe and water outlet pipe etc. are wrapped up with baffle plate

Insulating properties can be deteriorated after line irradiation；2nd, electrode and Faraday cup Heat Conduction Material are copper, by line Long-Duration Exposure, can be made
It is member；3rd, certain charged particle is also distributed with beam current tube space, these charged particles can influence Faraday cup pair
The measurement of Bunch current, Faraday cup is surrounded by baffle plate, and baffle plate is connected with device housings and beam current tube again, such spatial distribution
Charged particle would not influence measurement of the Faraday cup to Bunch current.In order to by high-field electrode, Faraday cup, baffle plate and set
Standby miscellaneous part insulation is come, and traditional design structure is complex, is made troubles to assembling and maintenance.
Faraday cup generally carries driving equipment, when not in use by driving equipment away from beam-flow transmission line, no
The transmission of line is influenceed, is moved on beam-flow transmission line by driving equipment when in use, stop that line passes through, while surveying
Amount Bunch current size.Traditional design using Faraday cup and driving equipment as an entirety, it is whole after Faraday cup is damaged
Individual equipment can all scrap, it is impossible to recycle, while Faraday cup is fixed relative to the direction of equipment, it is unadjustable, to installation
Make troubles.

Described high energy high-current accelerator Faraday cup, described circular platform type intercept the material in face for dystectic 1~
2mm thick tantalum plate.The material of the vertex of a cone is dystectic tantalum or tungsten.
Beneficial effects of the present invention：Taken into full account following measures, that is, intercept face the dystectic material of material selection, general
The beam power that heat energy on interception face is quickly passed, reduced in unit area, is circle by Faraday cup structure design
Cone barrel structure.Interception face is made as taper cone barrel using the thick tantalums of 1~2mm, is sleeved on the water-cooled with cone-shaped groove
On body and weld together.Why taper barrel structure is designed as, because Faraday cup is intercepting line or measurement line
When flowing strong, the axis of taper cone barrel and the transmission direction of line overlap, in addition to the vertex of a cone and beam transfer direction are vertical, taper cone barrel
Inner surface all has certain angle with beam transfer direction, and the contact area in face is intercepted so as to increase line and Faraday cup,
Reduce the power of unit area line.
The size of taper cone barrel cone angle is relevant with the beam power for blocking the unit area that section material can bear, unit area
Beam power is bigger, it is desirable to which circular cone cone angle is smaller, to increase the area in interception face, so as to cause circular cone axial length more long.Band
The difficulty come is exactly that tapered interior surface (including intercepting the inner surface of face taper cone barrel and the inner surface of water-cooled body cone-shaped groove) adds
Work is very difficult, if the precision of processing is not high, it is difficult to ensure that being face and face after interception face taper cone barrel and heat carrier weld together
Contact.The difficulty brought is the processing of conical top simultaneously, because centrum axial length is more long, cone angle is smaller, along with knife
The limitation of tool, the conical top for processing is not a point, but a slight cambered surface.For particle density into Gauss point
For the line of cloth, the beam power of unit area is maximum at beam center, and small cambered surface is in beam center approximate and line again
Direction is vertical, so as to 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, Faraday cup interception face is divided into circular platform type intercepts face
With vertex of a cone two parts.It is the conical tube that the thick tantalums of 1~2mm make that circular platform type intercepts face, and conical tube top is opening.Because
The particle density of line is into Gaussian Profile, and the unit area beam power at line edge is smaller, so opening taper cone barrel bottom
Angle becomes the big axial length to reduce taper cone barrel.The vertex of a cone is the small cylinder that a tantalum makes, and one is machined in the axial direction
Individual conical recess, its inner surface can intercept face smooth interior surfaces transition with circular platform type, form a complete tapered interior surface.Cause
For the vertex of a cone is shorter, processing conical recess is easier, and the groove top for processing is a point.2nd, water-cooled body conical recess top
An opening for cylinder is done in portion, and it is sized to be slightly smaller than the vertex of a cone.Circular platform type is intercepted into face and the welding of water-cooled body first when the 3, welding.
Circular platform type interception surface cover is entered in the conical recess of the cold body of copper water and they are compressed into shaping guarantee again they it using mould
Between be face contact, and put weld in a vacuum furnace together with the mould that compresses.Remove mould after being welded and circular platform type is blocked
Section vertex of a cone part is repaired, to ensure that its inner surface can form a complete and smooth circular cone with vertex of a cone groove inner surface
Surface.4th, in the vertex of a cone being packed into the cylinder shape groove at the top of the cold body of copper water by the technique of cold set or hot jacket, vertex of a cone diaphragm seal and
Weld together with water-cooled body after the vertex of a cone is compressed, the vertex of a cone is sealed in water-cooled body.
Improvement more than, there is following beneficial effect：Faraday cup intercepts face and water-cooled body for face contacts, effectively
Increase water-cooled effect；Face cone top easy processing is intercepted, and the vertex of a cone for processing is a point；The subtended angle for boring bottom is effective
