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.
