Embodiment
Below from principle of the present invention, the present invention is elaborated.
The present invention adopts low remanence ratio magnetic core to replace the high remanence ratio magnetic core previously usually adopted, and low remanence ratio magnetic core can by saturation induction density B within the pulse spacing
sautomatically reset to residual magnetic flux density B
rnamely the incremental magnetic induction Δ B of magnetic core can reuse under multiple pulse, so only need magnetic core Flux consumption to be greater than the weber integration of individual pulse, magnetic core all can not be saturated under continuous multiple impulse action, which greatly improves the magnetic core utilization ratio that multiple-pulse exports IVA induction cavity.
The key that multiple-pulse IVA induction cavity involved in the present invention is implemented is, low remanence ratio magnetic core (can usually be less than 1 μ s) within extremely short pulse spacing Rapid reset is to initial magnetization state (residual magnetic flux density Br).In fact, magnetic core self-resetting capability depends primarily on the pulse permeability of energized circuit connected mode and core material.When magnetic core is in the pulsed field magnetization stage, stored energy in magnetic core; When excitation terminates, magnetic core coil is equivalent to current source, and in magnetic core, stored energy needs to be discharged by external circuit.Magnetic core stored energy discharges completely, and exciting current gets back to the time of null value, is exactly the moment of magnetic core Self-resetting to remanent magnetism Br.Therefore, external circuit load impedance is higher, and the bucking voltage amplitude at magnetic core two ends is larger, and the speed that magnetic core releases energy is faster, and the time returning to remanent magnetism needs is shorter; When simultaneously magnetic core pulse permeability is less, magnetic core coil hinders the ability of curent change more weak, then exciting current return to zero time shorter, the magnetic core Self-resetting time is also shorter.The core material suitable by optimum choice and magnetic core technique for coiling, and field circuit reasonable in design, the self-recoverage time of core material can be less than 1 μ s.At present, the low remanence ratio magnetic core Self-resetting shortest time of bibliographical information is less than 500ns.Therefore, the induction cavity mentioned by the present invention can realize.
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are elaborated.
As shown in Figure 1 and Figure 2, of the present invention bursting exports multipulse megavolt level induction cavity, comprises cavity 1, is positioned at cavity and the coaxially arranged inner core 7 of cavity, magnetic core 6, cathode 3 and High-Voltage Insulation pile 2.Inner core, cathode and High-Voltage Insulation heap are axially arranged successively along cavity, and magnetic core is arranged around inner core.Region between High-Voltage Insulation heap outer wall and induction cavity inwall is induction cavity primary area 10, and the region in High-Voltage Insulation heap is induction cavity secondary region 11.

r/ B
s<0.12, incremental magnetic induction Δ B=B
s-B
r=1.1T, core material duty ratio k ≈ 0.7.Eight (external diameter is about 970mm) magnet rings are used, magnetic core net sectional area S in induction cavity
o=770cm
2, the Flux swing that magnetic core can provide is about 85mVS.
Three pulses are exported for induction cavity.Prime multipulse generator produces 3 amplitudes and is about 1MV, and pulsewidth is about the electric pulse of 60ns, and the pulse spacing is 1 μ s.Fig. 3 is by 3 pulses of the generation of prime multiple-pulse generator, successively feed-in induction cavity.Fig. 4 be time scale amplify after individual pulse and weber integration, can find out that the weber integration of individual pulse is about 80mVS, be less than the Flux consumption of induction cavity inner magnetic core, therefore magnetic core can not be saturated within each pulse duration.
For above magnetic core parameter, set up induction cavity Three dimensional transient electromagnetic model, calculate induction cavity and export pulse, as shown in Figure 5.Induction cavity exports the electric pulse that 3 amplitudes are about 920kV, and compared to feed-in pulse, induction cavity exports pulse and approximately postpones 25ns, and pulse front edge slows down slightly, and amplitude reduces slightly, and it is identical with the feed-in pulse spacing that induction cavity exports the pulse spacing, is 1 μ s.
According to traditional high remanence ratio magnetic core, can only reset to magnetic core before first pulse arrives, cannot reset in the pulse spacing, this Flux consumption requiring magnetic core to provide is 3 × 80=240mVS.For high remanence ratio Amorphous Cores, residual magnetic flux density B
r≈ 1.0T, saturation induction density B
s=1.25T, incremental magnetic induction Δ B=B
s+ B
r=2.25T.Can calculate, need the net sectional area S=1500cm of magnetic core
2, compared with the induction cavity proposed with the present invention, core cross section is long-pending to be increased more than one times, and this will cause induction cavity physical dimension to enlarge markedly.As can be seen here, the induction cavity of the low remanence ratio magnetic core of employing proposed by the invention, has obvious advantage in multiple-pulse operation of bursting.

Further, the shape of cross section of radial projection of the present invention is arc-shaped, and the advantage of this shape reduces the outer peripheral electric field strength of metal grading ring, avoids field emission and the electrical breakdown caused thus.
Further, the inner surface of metal grading ring of the present invention is the arc surface to inwardly projecting.The advantage of this shape is protection insulation subring, stops the bombardment of the sheaths duplet insulation subring of induction cavity secondary emission.
In addition, induction cavity primary area of the present invention adopts liquid medium insulation, and induction cavity secondary region of the present invention is vacuum.The advantage of this structure is: elementary employing fluid insulation improves the power density of induction cavity, and secondary employing vacuum insulation is convenient to drive magnetic insulation transmission line and vacuum intense current electron-beam diodes.
Further, feed-in pulse of the present invention reaches cathode through angle transmission line 5, feed-in pulse, according to the principle of " etc. the transmission times such as transfer impedance ", is divided into four tunnels and arrives cathode excircles, realize feed-in pulse current and be uniformly distributed with magnetic core evenly excitatory by angle transmission line.
