Presented are voltage measurements taken near the load region on the Z pulsed-power accelerator using an inductive voltage monitor (IVM). Specifically, the IVM was connected to, and thus monitored the voltage at, the bottom level of the accelerator

We are performing experiments with a 92-kV, 810-kA, 74.6-GW linear transformer driver (LTD) cavity. This cavity generates a ∼100 ns power pulse from DC-charged capacitors in a single step. Our experiments start with an existing 100-kV, 490-kA LTD c

In this article we present the design and test results of the most powerful, fast linear transformer driver (LTD) stage developed to date. This 1-MA LTD stage consists of 40 parallel RLC (resistor R, inductor L, and capacitor C) circuits called “br

We demonstrate that a wide variety of current-pulse shapes can be generated using a linear-transformer-driver (LTD) module that drives an internal water-insulated transmission line. The shapes are produced by varying the timing and initial charge vol

The increase in time-integrated divergence of a 1.7-MeV, 10-MA relativistic electron beam due to transport over 10 cm in a gas cell filled with 1 and 6 Torr of nitrogen was measured. The divergence was characterized by a multiple-pinhole beam samplin

The inverse triax diode is a low‐impedance, high‐power electron beam diode. A magnetically unbalanced electron flow in the outer gap, which results in an outward pinch, distinguishes this design. Particle code simulations show that this flow has

Operation of a new type of high‐power electron diode, the bidirectional voltage‐dividing (BVD) diode, has been demonstrated on a 1‐MV, 2.5‐MA, 20‐ns accelerator. This diode consists of a forward‐ and an inverse‐triaxial diode in series.

We describe a method for the induction of different polymorphic forms of actin filament paracrystals. This polymorphism is probably based on differences in the stagger and/or polarity of adjacent filaments in single-layered paracrystals and by superp

Fibrinogen molecules sprayed on mica, dried in vacuo and shadowed with platinum appear as trinodular rods. We describe here the flotation technique of negative staining by which we were able to visualize individual fibrinogen molecules. The fibrinoge
