OPTIMIZING THE CAPTURE PROCESS IN OPTICAL TRAPS

We present techniques for the most efficient capture of atoms in a mod ified vapor-cell magneto-optical trap. We explain how changing the siz e and power of the trapping beams affects the capture rate of the trap . We calculate the requirement of wall coatings designed to minimize t he interaction of an alkali vapor with the wall and explain how this a ffects trapping efficiency. Finally, we present measurements of the pe rformance of a ''Dryfilm'' coated cell.
