The versatility and usability of quantum simulation using ultracold atoms is often limited by the amount of data one can collect in a given time to achieve sufficiently good statistics. This is true in particular for measurements of phase diagrams or higher order correlations where many parameters are tuned simultaneously. In this new Lithium-6 experiment built at Heidelberg University this issue is addressed with the goal to reduce cycle times to below one second to make a step towards programmable quantum simulation.
In this talk, I will give an overview of the already implemented features designed to enable high cycle rates, in particular the compact vacuum system including an octagonal, nano-texture coated glass cell, versatile magnetic field coils and a 0.66 NA objective, as well as giving an outlook on the next steps including the optical dipole trap setup at 532 and 1064nm.
A very compact setup using a 2D-MOT allows to shrink the size of the vacuum apparatus to less than 50cm. The optical setup to manipulate the system has been designed in a modular way to easily update or exchange individual parts. From this we expect an increase in stability of the setup and higher fidelities, repeatability and debuggability.
