    "abstract": "We study the properties of a Rb magneto-optic trap loaded from a commercial\ngetter source which provides a large flux of atoms for the trap along with the\ncapability of rapid turn-off necessary for obtaining long trap lifetimes. We\nhave studied the trap loading at two different values of background pressure to\ndetermine the cross-section for Rb--N$_2$ collisions to be 3.5(4)x10^{-14} cm^2\nand that for Rb--Rb collisions to be of order 3x10^{-13} cm^2. At a background\npressure of 1.3x10^{-9} torr, we load more than 10^8 atoms into the trap with a\ntime constant of 3.3 s. The 1/e lifetime of trapped atoms is 13 s limited only\nby background collisions.",
