Abstract: An example method includes directing gas, via one or more first valves, from within an inner electrode to an acceleration region between the inner electrode and an outer electrode that substantially surrounds the inner electrode, directing gas, via two or more second valves, from outside the outer electrode to the acceleration region, and applying, via a power supply, a voltage between the inner electrode and the outer electrode, thereby converting at least a portion of the directed gas into a plasma having a substantially annular cross section, the plasma flowing axially within the acceleration region toward a first end of the inner electrode and a first end of the outer electrode and, thereafter, establishing a Z-pinch plasma that flows between the first end of the outer electrode and the first end of the inner electrode. Related plasma confinement systems and methods are also disclosed herein.

Abstract: A fusible target is embedded in a high Z liner, ohmically heated and then shock wave heated by implosion of an enveloping high Z liner. The target is adiabatically heated by compression, fusibly ignited and charged-particle heated as it is being ignited. A shock front forms as the liner implodes which shock front detaches from the more slowly moving liner, collides with the outer surface of the target, accelerates inward, rapidly heating the target, adiabatically compressing the target and liner and amplifying the current to converge the liner mass toward a central axis thereby compressing the target to a fusion condition when it begins to ignite and produce charged particles. The charged particles are trapped in a large magnetic field surrounding the target. The energy of the charged particles is deposited into the target to further heat the target to produce an energy gain.

Abstract: A high voltage pulse power generating circuit capable of providing energy recovery is disclosed. The energy efficient pulse generating circuit source comprises a high voltage charge storing element which is periodically discharged into a compressor circuit. An energy recovery circuit coupled to the compressor circuit reverses the polarity of energy dissipated by the pulse power generating circuit and transfers the waste energy back to the power source. In a preferred embodiment, the pulse power generating circuit of the present invention utilizes an SCR switch for periodically discharging the charge storing element. This embodiment of the present invention provides pulses consistently and will not provide even a single missed pulse.

Abstract: A digital signal processor including a digital FIR filter and memory for storing filter coefficients operates at a reduced power level by using array multipliers that calculate partial products only when the partial products in a preceding row of the array have stabilized. The dynamic CMOS adder arrays in each multiplier are triggered to perform their evaluations only after predetermined time periods have elapsed, which are sufficient to permit the preceding row to stabilize. Coefficients are addressed from the memory using low-power addressing circuits, such as a Gray code counter or a one-bit wide circular shift register, so that the overall digital signal processor consumes a reduced amount of power during memory addressing.

Abstract: A configuration of two opposed electrodes with conical depressions and symmetry around an axis along which there is an applied steady magnetic field, is supplied with a pulsed voltage and current to create an azimuthally very uniform pre-ionization cylinder of a working gas as a precursor to stable and accurate compression of the working gas into a Z-pinch plasma photon source or plasma target for laser-pumped photon sources. A further compound hollow electrode configuration permits the generation of a cool, dense, core plasma surrounded and compressed by a hot liner plasma. Modulation of the radial density profile within this core can provide optical guiding for a laser-pumped recombination laser.

Abstract: A high energy photon source. A pair of plasma pinch electrodes are located in a vacuum chamber. The chamber contains a working gas which includes a noble buffer gas and an active gas chosen to provide a desired spectral line. A pulse power source provides electrical pulses at voltages high enough to create electrical discharges between the electrodes to produce very high temperature, high density plasma pinches in the working gas providing radiation at the spectral line of the source or active gas. Preferably the electrodes are configured co-axially with the anode on the axis. The anode is preferably hollow and the active gas is introduced through the anode. This permits an optimization of the spectral line source and a separate optimization of the buffer gas. Preferred embodiments present optimization of capacitance values, anode length and shape and preferred active gas delivery systems are disclosed. Preferred embodiments also include a pulse power system comprising a charging capacitor and a magnetic compression circuit comprising a pulse transformer. A heat pipe cooling system is described for cooling the central anode.
