The spreading angle of an electrospray of Formamide with 5-10 LiCl by mass has been measured to be 18 inches in vacuum, for conditions close to minimum stable flow. A single-stage einzel lens was able to re-focus the spray, as predicted by paraxial ray theory. In addition, a time-dependent 1-D numerical model of the cone-jet-spray structure is described, and initial results presented.
