Title:

A Recipe to Make Zeolite Ion Source for Plasma Diagnostics Beam

Date of publication:

Sep. 2005

Key words:

alkali ion source, zeolite, substitution reaction, plasma diagnostics

Abstract:

A mathematical model is presented to describe the replacement process to make zeolite containing a particular species of alkali ions for the beam source. The fraction of the alkali ions trapped in zeolite lattice can be expressed as a function of the times of substitution reaction in a concise recursion formula. The formula is used for a simple estimation of efficiency for making alkali zeolite in terms of time and cost. A rough comparison between the model and a trial is presented.
