We present progress on developing a new setup for producing a Fermi gas of 6Li 87Rb. Our next-generation ultracold bialkali polar molecule apparatus features a compact vacuum design and rapid cycling time. By incorporating a short-range lithium Zeeman slower into the 2D magneto-optical traps (MOT) for two species in series, we achieve an atomic loading rate of 1 × 1010 atoms/s for 6Li and 6 × 108 atoms/s for 87Rb, promising an excellent starting point for the rapid production of double-degenerate lithium-rubidium atomic mixtures. Additionally, we discuss theoretical predictions and experimental proposals for stimulated Raman adiabatic passage (STIRAP) of LiRb molecules to the vibrational ground state, a critical step in preparing a deeply degenerate Fermi gas of LiRb molecules.
