  We report on the production of a rubidium Bose-Einstein condensate in a
simplified vacuum apparatus. Magneto-optical traps with large numbers and
ultra-high vacuum for moderately long conservative trap lifetimes of 16 seconds
are sequentially obtained with light induced rapid atomic vapor pressure
modulation. Subsequent evaporative cooling is carried out in two stages in a
hybrid magnetic quadrupole plus optical dipole trap. High evaporation
efficiencies are observed in both stages and $^{87}$Rb BECs with more than
10$^5$ atoms can be reliably produced with total evaporation time of only 9.5
seconds.
