Surface properties of some commercially available spherical glass laser fusion pellets

IMMA and SIMS analyses may provide insight useful in understanding the variations in hollow glass spheres from shell to shell and batch. Since suitable calibration standards are not presently available for the alkali metals and boron, these results should be interpreted only as relative measurements of batch and shell variations. These instruments have yielded absolute measurements of silicon concentrations. Deuterium and tritium have been observed at very low concentrations in the glass and the experimental data are in agreement with existing solubility data.
