    "abstract": "The fields produced by a long beam with a given transverse charge\ndistribution in a homogeneous vacuum chamber are studied. Signals induced by a\ndisplaced finite-size beam on electrodes of a beam position monitor (BPM) are\ncalculated and compared to those produced by a pencil beam. The non-linearities\nand corrections to BPM signals due to a finite transverse beam size are\ncalculated for an arbitrary chamber cross section. Simple analytical\nexpressions are given for a few particular transverse distributions of the beam\ncurrent in a circular or rectangular chamber. Of particular interest is a\ngeneral proof that in an arbitrary homogeneous chamber the beam-size\ncorrections vanish for any axisymmetric beam current distribution.",
