Title (EN) ELECTRIC PULSED POWER VACUUM PRESS
(FR) PRESSE A VIDE A COURANT ELECTRIQUE PULSE
Abstract:
(EN) An electric pulsed power vacuum press assembly (10) is provided for delivering high-power, short-duration electrical pulses to a selected sample (11) which is simultaneously subjected to mechanical compression. A hydraulic press (14) provides mechanical compressive force to a press insert member (12) containing the sample (11). Pulsed electrical power is delivered by a power supply assembly (16) and vacuum by a vacuum assembly (18). The electrical pulsed power is delivered through the sample (11) along an electrical pathway (49) characterized by very low inductance and resistance. The preferred electrical pathway (49) exclusively utilizes parallel plate conductor portions and coaxial line portions. The assembly (10) is adapted to provide very high short duration temperatures and is used for purposes such as synthetic diamond production.
(FR) L'invention se rapporte à un ensemble presse à vide à courant électrique pulsé (10), qui fournit des impulsions électriques de courte durée et de puissance élevée à un échantillon sélectionné (11), lequel est simultanément soumis à une compression mécanique. Une presse hydraulique (14) applique une force compressive mécanique à un élément de presse rapporté (12) contenant l'échantillon (11). Le courant électrique pulsé est fourni par une unité d'alimentation (16) et le vide est produit par une unité (18) prévue à cet effet. Le courant électrique pulsé est appliqué à travers l'échantillon (11) le long d'une voie électrique (49) se caractérisant par une inductance et une résistance très basses. La voie électrique préférée (49) utilise exclusivement des parties conductrices à plaques parallèles et des parties de lignes coaxiales. L'ensemble (10) est destiné à fournir des températures très élevées de courte durée et est conçu notamment pour la production de diamant synthétique.
