Abstract:
A resilient multi-layer container (10) is configured to receive a quantity of hyperpolarized gas and includes a wall with at least two layers (41,44), a first layer with a surface which minimizes contact-induced spin-relaxation and second layer which, e.g., is substantially impermeable to oxygen. The container is especially suitable for collecting and transporting 3 He. The resilient container can be formed of material layers which are concurrently responsive to pressure such as polymers, deuterated polymers, or metallic films. The container can include a capillary stem (26s) and/or a port or valve isolation means (31i) to inhibit the flow of gas from the main volume of the container during transport. The resilient container can be configured to directly deliver the hyperpolarized noble gas to a target interface by deflating or collapsing the inflated resilient container.
