[en] Luminosities and time structure for anti p p and pp colliders were examined at the DPF Snowmass meeting, and the results are summarized here as input for the design of detector components and systems. For bunched beams, the need to separate the beam orbits before the next bunch meeting gives a spacing between bunch collisions of about 800 nsec for anti p p and 100 nsec for pp. For the beam emittance assumed, as many as 25 interactions per bunch collision should be possible giving luminosities of up to 3 x 10³² and 2.5 x 10³³ cm^-2sec^-1 for anti p p and pp, respectively. Unbunched pp beams give a better duty cycle, but require greater beam intensities for a given luminosity. Synchrotron radiation will damp the beams at these high energies and may allow one to maintain constant luminosity during a run
