Abstract
A cluster ion synthesis process utilizing a containerless environment to grow in a succession of steps cluster ions of large mass and well defined distribution. The cluster ion growth proceeds in a continuous manner in a plurality of growth chambers which have virtually unlimited storage times and capacities.
Claims10
A method of producing cluster ions which comprises:
- a) generating a neutral gas,
- b) introducing said neutral gas into a first container which contains a first cluster ion of n nuclei (n.gtoreq.1), said neutral gas reacting with first cluster ion to form a second larger cluster ion,
- c) transferring said second cluster ion to a second container,
- d) reacting said neutral gas with said second cluster ion to form a third larger cluster ion,
- e) transferring said third cluster ion to a third container, said transferring and reacting steps are repeated a plurality of times to produce cluster ions of a specific size and energy.
