Dynamic aperture of low beta lattices at Tevatron collider

A comparative study of the dynamic aperture for several Tevatron lattices is presented with emphasis on the new low beta insertions. The results of tracking calculations indicate that the phase I ( beta * approximately=50 cm at both B0 and D0) lattice will have about twice the acceptance of the present machine. However, the predicted acceptance for phase II ( beta * approximately=25 cm) is 40% below that of the present machine.<
