Reaching low temperatures in dilute atomic clouds is a pivotal step in many atomic physics experiments and reaching quantum degeneracy is often achieved by employing evaporative cooling as the final cooling stage. However, this often gives one of the main contributions to the cycle time. Here, we present progress towards preparing a degenerate Fermi gas of lithium in an optical lattice in short timescales with no or minimal time required for evaporative cooling. We improve our MOT loading rates with a Zeeman slowing beam in our transversal cooling 2D MOT. This approach will help us shorten overall cycle times to less than 2 seconds. Shorter cycle times will allow for much higher data rates in our new quantum gas microscope, which will feature two modes of operation for both analogue quantum simulation and digital fermionic quantum information processing.
