Atom Trap Trace Analysis of Ca Isotopes
Tóm tắt
In our experiment we aim at the detection of the rarest, naturally occuring calcium isotope
$$^{41}$$
Ca by means of atom trap trace analysis. On basis of single-atom detection of
$$^{46}$$
Ca our present sensitivity for
$$^{41}$$
Ca is estimated to be 1 atom per hour at an abundance of 10
$$^{-12}$$
. To reach a sensitivity at the level of natural abundance, which is 10
$$^{-14}$$
, we need to reduce atomic beam losses. To achieve this, optical compression of the atomic beam is a promising option. We use Monte Carlo Simulations to demonstrate that optical compression of the atomic beam increases throughput of the atomic beam as well as isotope selectivity.
