    "abstract": "The successful commissioning and operation of the PEP-II asymmetric e+e-\ncollider motivated further studies to increase luminosity. In this paper, we\ndiscuss a modification of the PEP-II lattice to reduce the vertical beta\nfunction at the Interaction Point (IP) from the design value of 1.5cm to 1.0cm.\nThis could potentially reduce the colliding beam size, increase particle\ndensity at the IP and the probability of beam-beam interactions. In this paper,\nwe outline the optics modifications, discuss tracking simulations, and overview\nmachine implementation.",
