Recent advances in the study of a long pulse relativistic backward wave oscillator 长脉冲相对论性倒波振荡器的研究进展
F. Hegeler, E. Schamiloglu, S. Korovin, V. Rostov
Laser interferometry was recently used to diagnose plasma formation and evolution in the slow wave structure (SWS) of a relativistic backward wave oscillator (BWO) during the course of microwave generation. The results indicated that plasma from the cutoff neck inlet contributed to the termination of the high power microwave pulse. In an effort to mitigate this pulse shortening effect, the authors have replaced the cutoff neck with a Bragg reflector. As part of these studies, they have observed the cross-excitation instability because of the particularly shallow-ripple SWS used. They present results from recent experiments performed with the long pulse relativistic BWO, including the implementation of a hybrid-hard tube BWO at the University of New Mexico (UNM).
近年来,激光干涉测量被用于诊断相对论性倒波振荡器(BWO)微波产生过程中慢波结构(SWS)等离子体的形成和演化。结果表明,来自截止颈入口的等离子体有助于高功率微波脉冲的终止。为了减轻这种脉冲缩短效应,作者用布拉格反射器代替了截止颈。作为这些研究的一部分,他们已经观察到交叉激发不稳定性,因为使用了特别浅的波纹SWS。他们介绍了最近用长脉冲相对论BWO进行的实验结果,包括在新墨西哥大学(UNM)实现的混合硬管BWO。

Three channel pulse power system for underwater acoustic source 水声声源三通道脉冲电源系统
P. Adair, L. H. Fry, R. Williams
A three channel pulsed power system has been developed at the US Navy Coastal Systems Station in Panama City, Florida to provide power for underwater acoustic sources. In the present configuration, the system is capable of providing continuous operation at repetition rates up to 15 Hz and with energies up to 1.5 kJ per pulse per channel into a broad range of loads including spark-type underwater acoustic sources. The system includes three independent banks each of which contain two switcher-type power supplies, each capable of an energy output of 8 kJ/s at 3.2 kV. A highly flexible control system allows the construction of pulse trains with arbitrary trigger timings for each bank. High power silicon controlled rectifiers (SCRs) are used to form the pulse trains. The system is currently located on the deck of a remote controlled QST-35A US Navy target drone boat and provides power for three underwater spark gap acoustic sources (sparkers). The system was recently demonstrated at an Advanced Concept Technology Demonstration (ACTD) military exercise in Newfoundland, Canada.

This device consists of a generator solenoid (the first cascade) with internal and external diameters of 175 mm and 200 mm respectively and a length of 500 mm, and two internal cascades with diameters of 28/spl times/35 mm and 12/spl times/17 mm and a length of /spl sim/200 mm.

The MC-1 generator solenoid is powered with a current of 4-5 MA. MC-1 generator operation time (without powering time and HE-charge detonation time) is about 15 /spl mu/s, maximum liner implosion velocity is more than 6 km/s, the magnetic field derivative reaches values of /spl sim/5 10/sub 13/ Gs/s.

Plug and play solid state switching system for laser applications 即插即用固体开关系统的激光应用
A. Welleman, U. Schlapbach, E. Ramezani
Reliable, long life, and low maintenance switching of 3-5 kA (to 5 kA//spl mu/s) for repetitive short pulses (5-100 /spl mu/s) for applications such as laser switching and driving pulse shaping transformers has been limited in the past by the availability of switching system technologies. A new switching system is presented that increases peak current and di/dt capabilities and reduces dynamic energy loss. This solid state system uses a very fast triggering circuit. Since the power supply for the trigger-unit is a separate unit, the system has "plug and play" operation. The quick and strong current source gate-unit, in combination with the low inductance thyristor housing, allows very fast turn-on with low losses. Blocking voltages of 4.5 kV (3 kVdc) per device are possible, and with simple series connections, higher ratings can be achieved. The simplicity of the power supply and the integrated trigger-unit as well as the use of optimized silicon wafer geometries, leads to a more cost effective solution compared to actual solid state systems. Capabilities are discussed with respect to reliable management of pulse widths, repetition rates, voltage levels and dynamic losses.
对于重复短脉冲(5-100 /spl mu/s),如激光开关和驱动脉冲整形变压器等应用,可靠、长寿命和低维护的3-5 kA(至5 kA//spl mu/s)开关在过去受到开关系统技术可用性的限制。提出了一种新的开关系统,提高了峰值电流和di/dt能力,降低了动态能量损失。这个固态系统使用一个非常快的触发电路。由于触发单元的电源是一个单独的单元,因此系统具有“即插即用”操作。快速和强大的电流源门单元,结合低电感可控硅外壳,允许非常快速的开通和低损耗。每个设备的阻断电压可以达到4.5 kV (3 kVdc),并且通过简单的串联连接,可以实现更高的额定值。与实际的固态系统相比,电源和集成触发单元的简单性以及优化硅片几何形状的使用,使解决方案更具成本效益。讨论了脉冲宽度、重复率、电压水平和动态损耗的可靠管理能力。

Water treatment by pulsed streamer discharges 脉冲流光排放水处理
I. Lisitsyn, H. Nomiyama, S. Katsuki, H. Akiyama
The reliable and durable reactor for wastewater treatment by pulsed streamer discharges is designed and tested. Uniform streamer discharges were obtained in water at pulsed electric loading. The volume of these discharges exceeds 200 cm/sup 3/ and the energy delivered to the discharge reached 40-400 J depending on the applied voltage. High amplitude of the voltage pulse applied to the reactor requires improved electric insulation to prevent the flashovers along the reactor surface both in water and air. High energy deposition due to high discharge current adds the requirements to the mechanical durability of the system. Small-size reactor with the volume of approximately 1 liter withstands successfully both high electrical and mechanical stresses. The reactor is designed for research purposes, however it can be upgraded to use in high repetition-rate regime necessary for applications.

A time-dependent one-dimensional model of ablation-controlled arcs in electrothermal launchers 电热发射装置中烧蚀控制电弧的一维时变模型
Baoming Li, Hong-zhi Li
High-pressure discharges in ablative capillaries are used to couple electrically stored energy sources to hot plasma jets efficiently, for example, as plasma sources in launchers. A time-dependent quasi-one-dimensional model is developed for studying high-pressure discharges in ablative capillaries. As opposed to most of the previous work, a modified method calculating thermodynamic and transport properties of multi-component plasma under LTE conditions and a semi-empirical scaling law for the fraction of blackbody radiation that is transmitted through the ablating vapor for insulators under high heat flux conditions are utilized. With regard to the numerical code, the authors have examined the effects of the explicit two-step scheme of MacCormack and implicit continuous-fluid Eulerian scheme, respectively. The calculations show that some of the well-known experimental features of these kinds of discharges are confirmed by the numerical solutions obtained here. Numerical simulation was compared against experimental results obtained by the authors.

NO/sub x/ and SO/sub 2/ removal by pulsed power at a thermal power plant 热电厂脉冲功率去除NO/sub x/和SO/sub 2/
S. Tsukamoto, T. Namihira, D. Wang, S. Katsuki, H. Akiyama, E. Nakashima, A. Sato, Y. Uchida, M. Koike
Recently various methods involving gas discharges and electron beams have been studied for the removal of NO/sub x/ and SO/sub 2/ from flue gases. The recent development of repetitive pulsed power generators gives the pulsed streamer corona discharges a chance of success in the removal of NO/sub x/ and SO/sub 2/. Experiments for the removal of NO/sub x/ and SO/sub 2/ using actual flue gases were performed at a thermal power plant. The results showed that about 90% of NO and about 50% of SO/sub 2/ were removed at a flow rate of 0.8 l/min and a repetition rate of 7 pulses per second (pps). The removal ratio of NO varied inversely proportional to the gas flow rate. The energy efficiency of NO removal was 900 /spl mu/mol/Wh when 50% of NO was removed.

Wide-range medical ozonator with precise low-concentration ozone generation 宽范围医用臭氧发生器,精确低浓度臭氧生成
S. Buranov, V. Gorokhov, V. Karelin, P. B. Repin
Investigation results of dielectric barrier discharge with preliminary gap ionization and development of medical ozonator with O/sub 3/ output concentrations in the range from 10 to 10000 /spl mu/g/1 are presented. Thin structure of microchannels and their current characteristics are studied. Wide dynamic range is provided by variations of pulse repetition rate of discharge powering. High precision of ozone synthesis is performed at the expense of dielectric barrier discharge initiation and application of short powering pulses.
介绍了介质阻挡放电初步间隙电离的研究结果,以及O/sub - 3/输出浓度在10 ~ 10000 /spl mu/g/1范围内的医用臭氧发生器的研制。研究了微通道的薄结构及其电流特性。放电功率脉冲重复率的变化提供了宽的动态范围。臭氧合成的高精度是以介质阻挡放电的产生和短功率脉冲的应用为代价的。

Active former of monocycle high-voltage subnanosecond pulses 单周期高压亚纳秒脉冲有源发生器
V. Shpak, M. R. Oulmascoulov, S. Shunailov, M. Yalandin
Experiments have been performed to investigate the operating modes of a generator of 2/spl times/500-ps bipolar high-voltage, nanosecond pulses with the double amplitude (270 kV) close to that of the charge pulse of the RADAN-303 nanosecond driver. The generator contains an additional peaker shortening the risetime of the starting pulse and a pulse-forming line with two untriggered gas gaps operating with a total jitter of 200 ps.
实验研究了2/spl次/500-ps双极性高压纳秒脉冲发生器的工作模式,其双幅值(270 kV)接近RADAN-303纳秒驱动器的电荷脉冲。发电机包含一个额外的峰值,缩短了启动脉冲的上升时间,还有一条脉冲形成线,其中有两个未触发的气隙,总抖动为200ps。
