Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, technical scheme and beneficial effect are further illustrated.
The novel operation method of the high power klystron with anode of the present invention, comprises the following steps, and its electrical equipment connects figure referring to accompanying drawing 1:
The cathode power 1 using high power klystron controls beam electronic current；
The cathode power 1 adopting high power klystron is powered to the anode 6 of high power klystron in bias pressure mode: arranges anode between anode 6 and cathode power 1 to cathode resistor 2, arranges anode resistance to earth 4 between anode and ground.
The present invention also provides for the anode supply device of a kind of high power klystron with anode, its electrical equipment connects figure with reference to Fig. 1, cathode power 1 including high power klystron, the cathode power 1 adopting high power klystron is powered to the anode 6 of high power klystron in bias pressure mode: is provided with anode between anode 6 and cathode power 1 to cathode resistor 2, is provided with anode resistance to earth 4 between anode 6 and ground.
Under the method or apparatus of the present invention, the anode of klystron and negative electrode have same power supply to power, anode voltage and cathode voltage are opened simultaneously and cut off, thus, the present invention not only need not arrange anode modulation device on hardware, simplifies structure, and also simpler in sequential, traditional method is that anode voltage declines together with cathode voltage, and then anode voltage is gradually increasing and sets up beam electronic current.After electric discharge terminates, anode voltage drops to and cathode voltage isoelectric level, turns off line, and then anode declines together with cathode voltage.Sequential relative complex, the method anode of the present invention and cathode voltage be raising and lowering simultaneously, it is not necessary to complicated sequencing contro equipment.
nullWhy inventor adopts technique scheme，Be because inventor it have been investigated that，Why when providing suitable voltage to anode, klystron still cannot work，The anode current being because klystron has its particularity: namely the anode current of klystron is made up of two parts，One is form, to anode, the electric current flowing into anode from some bombardment of the beam electronic current of emission of cathode，Another is owing to bombarding the electric current flowing out anode that the secondary caused causes，And in order to ensure the safety of klystron，Anode current needs to be limited in smaller scope，This is accomplished by above-mentioned two electric current and reaches in a basic balance，To ensure less anode current，Simultaneously，Owing to absolute balance is extremely difficult to，Therefore anode always there will be the electric current of inflow and is higher than the situation of the electric current flowed into higher than the electric current of the electric current flowed out or outflow，Thus causing the sense of current of anode to change.Inventor thinks that the above-mentioned particularity just because of klystron anode makes general power supply mode cannot meet requirement, inventor proposes technical scheme according to this thinking, adopt bias pressure mode to anode supply, so that it can make the electric current flowing out anode and inflow anode reach good balance, and this power supply mode can adapt to the change in anode current direction.
nullOwing to the cathode high voltage of klystron can reach tens of kilovolt，This just requires that cathode resistor 2 and anode resistance to earth 4 must just be had higher insulating properties by anode，And instantaneous large-current can be produced in klystron electric discharge moment，So that cathode resistor 2 and anode resistance to earth 4 moment are subject to bigger impact by anode，This is accomplished by this two resistance and has good resistance to pressure，In order to reach above-mentioned requirements，The invention provides a kind of high-voltage bleeder，This high-voltage bleeder includes being layered the specified high-power high voltage resistance of the dozens of being arranged on High-Voltage Insulation plate，And it is furnished with shorting stub，Partial ohmic on high-voltage bleeder as anode to cathode resistor 2，Partial ohmic accesses circuit as anode resistance to earth 4，The anode adjustment to cathode resistor 2 and/or the resistance of anode resistance to earth 4 is realized by shorting stub shorted section resistance，Thus cathode resistor 2 and/or anode resistance to earth 4 are set in required resistance by anode.The arranging of this high-voltage bleeder can conveniently adjust anode to the all-in resistance of cathode resistor 2 and anode resistance to earth 4 and dividing point, and anode voltage is minimum for cathode voltage, is up to earth potential.When being embodied as, it is possible to high-voltage bleeder comprises the high-power high voltage resistance that 60 rated power is 300W, and single resistance is pressure more than 2.3kV, comprise 3.3k resistance 10,1k resistance 10,3.9k resistance 40, and according to high power klystron operating point, select dividing point.
The setting of the high-voltage bleeder in the present invention, can also implement function such as: after high power klystron normal operation, shorting stub is adopted to change the quantity and the different valued resistor of conversion accessing resistance, near high power klystron operating point, finely tune the resistance of anode resistance to earth 4, the output performance of high power klystron is optimized.
In high-voltage bleeder, the High-Voltage Insulation plate as supporting construction can be epoxy plate, and resistance can divide 10 layers of three-dimensional installation, utilizes space length to realize High-Voltage Insulation, and potentiometer is pressure reaches 80kV.
In order to measure anode current, sample resistance 3 is sealed between dividing point (namely Fig. 1 Anodic is to the position between cathode resistor 2 and anode resistance to earth 4) and the anode of high power klystron, it can be such as the sample resistance of 200 Ω, the voltage at the two ends of sample resistance 3 passes through incoming measurement system after voltage-frequency conversion module 8 carries out voltage-frequency conversion and realizes the measurement of the electric current of antianode, when flowing through the controller of anode, the cathode power 1 of high power klystron rapidly switches off antianode 6 and the power supply of negative electrode 5, to ensure high power klystron safety.This voltage to frequency convert module 8 can adopt AD650JNZ chip, in order to prevent anode 6 power-up peak current from damaging this module, it is possible to be provided with 10V Zener diode at input.
In the present invention, it is possible to adopt 100kV isolating transformer 9 to voltage-frequency conversion module for power supply, it is achieved cathode high voltage and power supply grid and isolation.
In the present invention, the cathode power 1 of high power klystron is required to realize the function of fast shut-off beam electronic current, such as can select to adopt pulse step modulation power source, when being embodied as, may require that pulse step modulation power source maximum output voltage 60kV, maximum output current is more than 30A, and the time that rapidly switches off, the energy discharged by load in fast switch-off processes was less than 10J less than 10 μ s.
Fig. 2 is the discharge waveform figure of the high power klystron of the operation method adopting the present invention.Wherein Q1_Uk is cathode voltage, and Q1_Ua is anode voltage, and Q1_Ik is beam electronic current, and Q1_Ia is anode current.Anode resistance to earth is 30k Ω, and cathode voltage is-52.5kV.Anode voltage enters into steady-state discharge state after first experiencing the transient process of about 100 μ s.When cathode voltage declines, anode voltage drops to-26kV, fall is more than partial pressure value-9kV, peak anode current reaches 600mA,, for flowing into anode, namely after the beam bombardment anode of emission of cathode, discharged rapidly by anode resistance to earth in direction, then anode voltage is reduced to partial pressure value, enters stable state.Stable state anode current is less than 10mA.Adopt as can be seen from Figure 2 the operation method of the present invention or anode supply device klystron can normal operation, and duty is good, and this has also confirmed inventor's correctness to the analysis conclusion of klystron anode particularity.
To sum up, the present invention simplifies high-power microwave source to a certain extent, it is to avoid due to the anode modulation device based on nonlinear device, improves the safety and reliability of Lower Hybrid and significantly reduces cost.
