Problems of Air-Borne Contamination in Handling of Pu F₄ Powders

Abstract: Studies were made of the air-borne contamination present during the operation of reducing plutonium tetrafluoride powder to the metal. Equipment design changes were made and operation technique changes were made until the amount of contamination present during operations was well below tolerance levels.

A Proposal For Reducing Impurities in a Stabilized Pinched Discharge (open access)

A Proposal For Reducing Impurities in a Stabilized Pinched Discharge

It is proposed to reduce the initial wall hangup and consequent plasma contamination of a stabilized pinched discharge by reducing the Bz pressure difference across the current sheath to nearly zero at early times. Two methods for accomplishing this are proposed, both involving multistage programming of the Bz system.
