We report on a simple oven-loaded magneto-optical trap (MOT) apparatus forthe creation of both molecular Bose-Einstein condensates (mBEC) and degenerateFermi gases (DFGs) of lithium. The apparatus does not require a Zeeman sloweror a 2D MOT nor does it require any separation or differential pumping betweenthe effusive atom source and the science chamber. The result is an exceedinglysimple, inexpensive, and compact vacuum system ideal for miniaturization. Wediscuss our work in the context of other realizations of quantum degenerategases by evaporation in optical dipole traps and illustrate that our apparatusmeets the key requirements of atom number and trap lifetime. We alsodemonstrate with this system the production of a mBEC, and we use it to observethe pairing gap of a strongly interacting two-component DFG in the BEC-BCScrossover regime.
