Abstract
SummaryWe present our arrangement of new apparatus for trapping Ca+and Al+ions. The apparatus consists of a compact vacuum chamber, linear quadrupole trap, one pair of Helmholtz coils, two pairs of saddle coils, and a magnetic shield. The new design respects the requirement of the large optical access for laser beam integration, a homogeneous magnetic field in the position of the ion in the trapping area, and an ultra-high vacuum regime to avoid interactions between residual gas and ions. The new apparatus is designed in a way so that all important subparts can be changed easily and allow us to minimize the time when the inner parts are exposed to the air during a component exchange. All parts of the arrangement, including the quadrupole trap, have been designed and developed by the Institute of Scientific Instruments in Brno, Czech Republic.
