An electrostatic storage ring for polar molecules is proposed, includi
ng an analysis of the ring dynamics, loading, and losses for experimen
tally practical parameters. It is shown that storage lifetimes on the
order of 10(3)-10(4) s can be expected for methyl fluoride under reaso
nable operating conditions. A design for the storage ring is presented
along with potential applications to molecular beam steering, molecul
ar collision physics, and surface deposition and lithography. Other ap
proaches to molecular storage are also briefly discussed. (C) 1997 Ame
