Development of a deterministic ion source based on ultracold atoms — •Cihan Sahin, Andreas Müllers, Jens Benary, and Herwig Ott — Technische Universität Kaiserslautern

A deterministic ion source using ultracold atoms can provide ions with low energy spread at high repetition rates. These properties are beneficial for experiments on ion interferometry or semiconductor doping.

In our experiment, a magneto optical trap (MOT) storing ⁸⁷Rb atoms acts as an ion source. The atoms are photoionized from the 5P_3/2 state with a 405 nm laser. Both electrons and ions are detected with channel electron multipliers (CEM). The electrons serve as triggers for the ions, which would enable us to predict and control the ions.

As a next step, the ions will be detected with a position sensitive multi channel plate (MCP) with a delay line detector (DLD) to characterize their energy spread and position resolution.

We discuss the status of the experiment and present results obtained so far.
