    "abstract": "We analyze the stop-band due to crab cavities for horizontal tunes that are\neither close to integers or close to half integers. The latter case is relevant\nfor today\u0027s electron/positron colliders. We compare this stop-band to that\ncreated by dispersion in an accelerating cavity and show that a single typical\ncrab cavity creates larger stop-bands than a typical dispersion at an\naccelerating cavity.\n  We furthermore analyze whether it is beneficial to place the crab cavity at a\nposition where the dispersion and its slope vanish. We find that this choice is\nworth while if the horizontal tune is close to a half integer, but not if it is\nclose to an integer. Furthermore we find that stop-bands can be avoided when\nthe horizontal tune is located at a favorable side of the integer or the half\ninteger.\n  While we are here concerned with the installation of a single crab cavity in\na storage ring, we show that the stop-bands can be weakened, although not\neliminated, significantly when two crab cavities per ring are chosen suitably.",
