This paper addresses the voltage droop compensation associated with long pulses generated by solid-stated based high-voltage Marx topologies. In particular a novel design scheme for voltage droop compensation in solid-state based bipolar Marx generators, using low-cost circuitry design and control, is described. The compensation consists of adding one auxiliary PWM stage to the existing Marx st...

Marx generators have been traditionally relegated as pulse-charging supplies for a variety of applications including the generation of High Power Microwaves, or RF energy. Compact models have served as suitable trigger generators for larger systems. However, recent work has demonstrated the compact Marx generators for directly generating RF energy. This paper discusses two compact Marx generato...

Slide 1 Marx was very critical of Malthus. He said that an abstract law of population did not exist for men (Marx, 1974). All historical modes of production have their own special laws of population which are valid only within their limits. Marx discussed the law of population, applicable to capitalist mode of production in chapter XXV of Capital, entitled, “The General Law of Capitalist Accumu...

1. The Problem. Marx is undeniably a fierce critic of a capitalist organization of economic activity. By what standards does Marx assess capitalism and find it objectionable? In many passages it seems that Marx's critique is based upon notions of justice and fairness which in his opinion capitalism flagrantly fails to satisfy. In the "Communist Manifesto," contrasting the phenomenon of exploita...

For Marx, work is the fundamental and central activity in human life and, potentially at least, a fulŽlling and liberating activity. Although this view is implicit throughout Marx’s work, there is little explicit explanation or defence of it. The fullest treatment is in the account of ‘estranged labour ’ [entfremdete Arbeit] in the Economic and Philosophical Manuscripts;1 but, even there, Marx ...

This paper has four related themes. It demonstrates that Marx’s Communism in its first or Socialist phase would recognize the essential inequality of labour on grounds of efficiency and growth. It offers an explanation for the apparent paradox that Marx and Engels championed a fully-fledged control system notwithstanding appreciation of the allocation functions of a competitive market system. I...

SLAC National Accelerator Laboratory (SLAC) has initiated a program to design and build a Marx-topology modulator to produce a relatively compact, low-cost, high availability klystron modulator for the International Linear Collider (ILC). Building upon the success of the P1 Marx, the SLAC P2 Marx is a second-generation modulator whose design further emphasizes the qualities of modularity and hi...

Marx modulators operated by solid-state switches (e.g. MOSFET, IGBT) offer an alternative to traditional high voltage (HV) modulators for rf power sources. They have the merits of compact size, high-energy efficiency, high reliability, pulse width control and cost reduction. However, Marx modulators need a complex voltage compensation circuit if they are employed in long pulse applications such...
