Abstract
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.
