Abstract[English]
A method of fabricating one or more glass cells includes drawing one or more glass capillaries from a source of glass material. The method includes performing a first conditioning of one or more inner surfaces of the one or more capillaries. The method includes sealing one or more first ends of the one or more capillaries using thermal energy. The method includes performing a second conditioning of the one or more inner surfaces after the sealing. The method includes purifying the one or more capillaries to increase a purity of a gas used to fill the one or more capillaries. The method includes filling the one or more capillaries using the gas after the purifying. The method includes pressurizing the one or more capillaries to a given pressure. The method includes sealing one or more second ends of the one or more capillaries using thermal energy.[French]
L'invention concerne un procédé de fabrication d'une ou plusieurs cellules en verre, comprenant l'étirage d'un ou plusieurs capillaires en verre à partir d'une source de matériau de verre. Le procédé comprend la réalisation d'un premier conditionnement d'une ou plusieurs surfaces internes dudit ou desdits capillaires. Le procédé comprend le scellement étanche d'une ou plusieurs premières extrémités dudit ou desdits capillaires à l'aide d'énergie thermique. Le procédé comprend la réalisation d'un second conditionnement de ladite ou desdites surfaces internes après le scellement étanche. Le procédé comprend la purification dudit ou desdits capillaires pour augmenter une pureté d'un gaz utilisé pour remplir ledit ou lesdits capillaires. Le procédé comprend le remplissage dudit ou desdits capillaires à l'aide du gaz après la purification. Le procédé comprend la mise sous pression dudit ou desdits capillaires à une pression donnée. Le procédé comprend le scellement étanche d'une ou plusieurs secondes extrémités dudit ou desdits capillaires à l'aide d'énergie thermique.
