    "abstract": "We demonstrate a combination of an isotopically purified atom beam and a\nmagneto-optical trap which enables the single atom detection of all stable\nisotopes of calcium (40, 42, 43, 44, 46 and 48). These isotopes range in\nabundance from 96.9 % (40Ca) to 0.004 (46Ca). The trap is loaded from an atomic\nbeam which is decelerated in a Zeeman slower and subsequently deflected over an\nangle of 30 degrees by optical molasses. The isotope selectivity of the Zeeman\nslower and the deflection stage is investigated experimentally and compared\nwith Monte Carlo simulations.",
