Development of a piezoelectric pulsed drop jet device for the preparation of nuclear targets

A piezoelectric pulsed drop jet device has been developed to produce deposits for nuclear measurements. Details are given concerning the construction and performance of the drop generator, the construction of a positioning mechanism and the developement of a steering system (based on a TRS 80 microcomputer). The complete system can produce rectangular and circular deposits of various dimensions and thicknesses. 235 U acetate deposits have been prepared in thicknesses varying from 10 μg/cm 2 to 2 mg/cm 2 and their quality is evaluated.
