National lab user facilities are federally sponsored research facilities available for external use to advance scientific or technical knowledge under the following conditions:
- Open - The facility is open to all interested potential users without regard to nationality or institutional affiliation.
- Competitive - Allocation of facility resources is determined by merit review of the proposed work.
- Free - User fees are not charged for non-proprietary work if the user intends to publish the research results in the open literature. Full cost recovery is required for proprietary work.
- Accessible - The facility provides resources sufficient for users to conduct work safely and efficiently.
- Collaborative - The facility supports a formal user organization to represent the users and facilitate sharing of information, forming collaborations, and organizing research efforts among users.
- Unique - The facility capability does not compete with an available private sector capability.
