Current measurement by Faraday effect on GEPOPU.

The design of an optical current sensor to be used in a pulsed power generator is presented. The current sensor is based on the polarization rotation by the Faraday effect. GEPOPU is a pulsed power generator, 110 kA, 120 ns double transit time, 1.

Fast plasma discharge capillary design as a high power throughput soft x-ray emission source.

We present the experimental details and results from a low energy but high repetition rate compact plasma capillary source for extreme ultraviolet and soft x-ray research and applications. Two lengths of capillary are mounted in two versions of a closely related design. The discharge operates in 1.

Simple holographic polarogram.

A new technique capable of obtaining quantitative values of the rotation angle of the polarization vector by using holography is presented. This is a two-stage holographic process; during the recording stage a hologram of the object of interest is obtained. The reference beam is composed of two beams that form a small angle between them and keep their polarization states at right angles to each other.

Eight-frame holographic interferometry system for transient plasma diagnostics.

A multiframe technique that uses Fresnel holography is described. Splitting of the initial pulse by means of 50/50 beam splitters provides two sets of eight consecutive pulses with approximately the same energy but with different angles. Each interferogram is recorded separately.

Archival and wide exposure latitude process for holography.

A high diffraction efficiency and wide exposure latitude holographic processing method, capable of producing archival quality holograms is presented. It consists of a solution stage physical development on CPA-1, followed by a fixing stage. Holograms thus obtained have a wide exposure latitude and high diffraction efficiency.
