There are various beam intercepting devices between the interaction point and the beam dumps of the SLC. Of these, the adjustable collimators, a fixed collimator, and the tune-up dumps are expected to intercept enough of the beam to warrant calculating the fluxes inside the interaction hall from them. The fluences of neutrons and photons in the interaction hall from these sources. Whether the beam has passed the interaction point or not is considered important in choosing a source term, primarily for photons. Neutron calculations are done only for giant resonance neutrons.

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.
