Accompanying drawing explanation
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is tunable arrangement outline drawing;
Fig. 2 is the structural representation of variable transmission diameter negative electrode；
Wherein: A is anode, B is that electron beam launches diameter adjustable cathode, and C is insulator, and D is motor, and E guides magnet.
Detailed description of the invention
As it is shown in figure 1, the present invention includes variable transmission strong current electron beam diameter negative electrode, anode, insulator are tightly connected composition vacuum chamber through vacuum.Under high voltage pulse drives, when anode and cathode is in spacingdUnder electric field intensity meet the transmitting threshold value of negative electrode, then strong current electron beam arrives anode, diode current flow under the axial magnetic field guiding magnet to produce guides.Insulator acts primarily as the effect supporting negative electrode, and its material is generally enhancing nylon.Guiding magnet to produce uniform axial magnetic field in vacuum chamber, magnetic field intensity is generally 1T.
As in figure 2 it is shown, negative electrode profile is column structure, inside is cylindrical structure, and sealing one end, one end is opening；It is followed successively by cathode shell 4, graphite cathode 5, distance piece 7 and graphite cathode 6 from outside to inside, can be seen that from position relationship the diameter of two graphite cathodes 5,6 is different.
What play Main Function in negative electrode is screw rod, and the surface at the two ends of screw rod is each provided with screw thread, and one end of screw rod arranges plus thread 3, and one end arranges left-hand thread 2.Screw rod sequentially passes through the sealing bottom surface of cathode shell 4, graphite cathode 5, distance piece 7, graphite cathode 6, plus thread 3 on screw rod and the screw-threaded engagement on graphite cathode 6, left-hand thread 2 on screw rod and the screw-threaded engagement on graphite cathode 5, screw rod is fixed on distance piece 7 by bearing, screw rod can only rotated clockwise or counterclockwise, and can not move along screw axis.In order to be able to rotate screw rod, being connected to a handle 1 with screw rod, handle 1 is arranged on the sealing bottom surface side of cathode shell 4, and handle is connected through cathode shell 4 and screw rod are fixing so that turning handle 1 just can drive screw rod to rotate.In order to be maintained in the process rotating screw rod, all parts in cathode shell 1 can not disorderly move, both fixing is carried out by screw 8 between distance piece 7 and cathode shell 4, distance piece 7 and cathode shell are connected as one, and screw 8 is connected to distance piece after cathode shell 4, graphite cathode 5.In order to ensure that graphite cathode 5 can move according to the axis of screw rod, therefore at a groove at side surface 10 of graphite cathode 5, the direction of fluting is parallel with the axis of screw rod, then again distance piece arranges a chock 11, the fluting 10 of chock 11 traverse graphite cathode 5, and the external diameter of chock 11 matches with the width of fluting 10 so that graphite cathode 5 can pass through fluting 10 and slide along chock 11.Adopting same principle, arrange a chock 13 in the side of graphite cathode 6, then arrange fluting 12 again on distance piece, graphite cathode 6 can slip in fluting 12 by chock 13.In order to ensure the displacement of graphite cathode 5, between cathode shell 4 and distance piece 7, therefore it is provided with location snap ring 9, limits the displacement of graphite cathode 5.
As shown in Figure 2, when after turning handle, screw rod is engaged with graphite cathode 5,6 respectively by screw thread, graphite cathode 5 just moves along screw rod towards the outside of cathode shell, and graphite cathode 6 is just internal mobile along screw rod towards cathode shell simultaneously, until graphite cathode 6 is fully retracted in distance piece, outside whole cathode shell, only leave graphite cathode 5.Same reason, reverse handle, and graphite cathode 5 just moves in cathode shell, and graphite cathode 6 moves outside cathode shell, until graphite cathode 5 is fully retracted in cathode shell.
When graphite cathode 5 exposes that after cathode shell, graphite cathode 6 is fully retracted in distance piece, graphite cathode 5 launches electronics, and graphite cathode 6 stops launching electronics；Same when graphite cathode 6 exposes that after cathode shell, graphite cathode 5 is fully retracted in distance piece, graphite cathode 6 launches electronics, and graphite cathode 5 stops launching electronics.Graphite cathode launches electronics to be needed to meet in Fig. 1dRequired distance.
The invention is not limited in aforesaid detailed description of the invention.The present invention expands to any new feature disclosed in this manual or any new combination, and the step of the arbitrary new method disclosed or process or any new combination.
