A report is made of experiments done in collaboration at Fermilab to measure large momentum transfer anti-pp and pp elastic scattering dsigma/dt's at 100 and 200 GeV/c. For the case of anti-pp scattering the intent was heightened by the 1980 discovery of a dip at 50 GeV/c near = t = 1.4 (GeV/c)/sup 2/; it was wondered if this structure would persist to 100 and 200 Gev/c. For pp, measurements by others seemed to indicate that the corresponding dip is present at 200 but not at 100 GeV/c; it was desired to confirm this. The experiments were done using a two arm magnetic spectrometer. Because of the relative scarcity of elastics it was necessary to have an adequately selective experimental trigger to dispose of most undesired events before recording information on magnetic tape. Scintillation counter hodoscopes were used in the implementation of this trigger. Results provide evidence that the anti-pp dip is present at both 100 and 200 GeV/c and that the pp dip may have an energy threshold below 100 GeV/c. pp data taken at 200 GeV/c agreed well with previous pp data at this energy.
